Computer-based Business Applications Word Processing

The need for writing is an everyday need. Each one of us needs to present ideas, thoughts, feelings and needs somehow or the other. Often this takes the form of the written word.(unit 3 computer based business applications word processing bcom notes) We prepare documents, letters and projects to express ourselves. Earlier, these documents were either written by hand or typed on typewriters. Both these methods were error prone. The documents needed to be retyped or rewritten each time an error was detected in it.

This was time consuming and wasteful. With the advent of the computer, this need was addressed to and a software was developed that could allow you to type and edit a document in realtime, on the computer screen. This was economical in terms of both time and resources. One could type a document, read it on screen and make the necessary changes and then take a printout on the paper. They also allowed you the facility of saving the document for future use, something that was not possible earlier.

unit 3 computer based business applications word processing bcom notes

This entire process of writing, typing, editing, saving and printing a document is called word processing. We have several software that provide us the facility of word processing, these are called the word processors, MS-Word is a word processor. It allows us to create, edit, print and save documents like reports, memos and even books for future retrieval.(unit 3 computer based business applications word processing bcom notes) MS-Word allow us to enhance and dress up our documents, and present them in a more effective manner.

MS-Word is an application software and member of MS-Office group. MS-Word is a word processing program. It is also WYSIWYG (What-you-see-Is-What-You-Get). It has several versions, like Word 95, Word 97, Word 2000, Word 2002 and MS-Word XP is the latest version. With each version, some new features are included.

Starting MS-Word: Click on the Start button, take the mouse pointer to All Programs and from All Programs menu, select Microsoft Word. The Window of MS-Word will open on the screen.

unit 3 computer based business applications word processing bcom notes

This window is divided into two parts:

1. Application window
2. Document window

Application Window: The outer window which has all the bars is known as application window. Application window has many elements. These are the following:

Title Bar: It is displayed at the top of the window. The name of the application and active file are displayed on the left hand side of the bar. On the right hand side, there are three buttons to minimize, maximize and close the window.

unit 3 computer based business applications word processing bcom notes

You can close the window by clicking the close button. Word program prompts you to save the unsaved work. If you want to save changes, click on Yes button otherwise click on Name button. If there are no changes in the document since it was last saved, the window will close without displaying any message.

Menu Bar: The menu bar has various menu option like File, Edit, View, Insert, Format, Tools, Table, Window and Help menus. On clicking a menu a list of options drops down. We call it a pull down menu or drop down menu. You may also use the Alt key in combination with the underlined letter of the menu to open the corresponding menu.

unit 3 computer based business applications word processing bcom notes

Toolbar: There are many types of toolbars available in MS Word.

Standard toolbar is placed below the menu bar. It has some File menu options like New, Open, Save, Print, etc.

Formatting toolbar has some Format menu options like Font, Font size, Bold, Italic, alignment, Colors, etc. Drawing toolbar has buttons or icons which activate tools for you to draw arrows, rectangles. circles, ovals, etc. into the document.

Status Bar: This bar is located at the bottom of the document window. It shows the status like present page number, total number of pages, line number based on cursor position, column number, spelling and grammar check status etc.(unit 3 computer based business applications word processing bcom notes) All these toolbars provide a quick way of performing operations that can be executed from the various menu.

Ruler: Ruler is the measuring tool of a document. There are two type of rulers available.

1. Horizontal ruler
2. Vertical ruler

Horizontal ruler is used to set the margins within which the text in the document is to be written. To change the left and right margins. point to a margin boundary immediately at the start or end of the white areas on the ruler.

unit 3 computer based business applications word processing bcom notes

Vertical ruler is used to set the top or bottom margin.

Scroll Bar: Word has two scroll bars-vertical and horizontal scroll bar.

Vertical scroll bar is used to move the document up or down by dragging the scroll box. You can drag the scroll box on the horizontal scroll bar left and right to see the contents on the left and right side of the page, if the page width is more than the screen width. These scroll bars are useful when the document contents are too big to fit in a single window.(unit 3 computer based business applications word processing bcom notes)

Task Pane: Task pane is the place from where you can open existing documents and create new documents. It displays the current program of applications.

Document Window: Document window is the blank white area where you type text, insert pictures, draw lines, circles, rectangles, etc. It is also known as the work area.(unit 3 computer based business applications word processing bcom notes) You can increase or decrease the work area by changing the margins on the rulers.

We can create a document, open document, save, print documents using the File menu. Suppose your teacher asked to make an assignment on the computer, you have to create a new document using the New command.(unit 3 computer based business applications word processing bcom notes)

Working in MS-Word

To prepare the document in MS-Word, We have to following five steps.

1. Typing: When you get a new document, you will see a vertica blinking line. This line is known as cursor. When you press a key pressed character is displayed where cursor is positioned. The letters numbers or symbols you type appear on the screen as the cursor move to the right. MS-Word has a special feature word wrap, that means a you type the text,(unit 3 computer based business applications word processing bcom notes) once the current line is full, extra characters move onto the next line automatically. In other word, you do not have press enter key to go to the next line.

You should press the enter key to begin a new paragraph or insen a blank line. So you can type all the data of your assignment in the similar way. After you have entered text,(unit 3 computer based business applications word processing bcom notes) you will need to edit the data But before learning to edit data, you need to know as to how to select text.

2. Editing Text: Editing text means correcting the spelling inserting or deleting some words and shifting text from one place to another in document. We will discuss Edit menu and other commands for editing the text later.(unit 3 computer based business applications word processing bcom notes)
3. Selecting Text: In MS-Word, you carr select text with the keyboard or the mouse.

Selecting Text With The Keyboard

You can select the text by using some key combinations.

(i) Word: To select a word, anywhere inside the word and double-click the mouse button.

(ii) Line: To select a line point in the selection bar area (then blank vertical bar on the left side of the document window) next to the line and click the mouse button. All the text on that line is selected.

unit 3 computer based business applications word processing bcom notes

(iii) Sentence: To select the sentence point anywhere inside the sentence. Press and hold the Ctrl key, and then click the mouse button. Release Ctrl Key. End punctuation and trailing spaces are automatically selected along with the sentence.

(iv) Paragraph: To select a paragraph point in the selection bar next to the paragraph and double-click the mouse button. The ending paragraph mark is selected along with the paragraph.

(v) Entire document: To select an entire document choose Edit, 109 Select All. Or point anywhere in the selection bar, press and hold Ctrl, click the mouse button, and then release Ctrl.

unit 3 computer based business applications word processing bcom notes

(A) Delete the text: You can delete select word, sentence, paragraph or whole document by pressing the ‘Del’ key.

(B) Replacing the text: You can replace old typed word. sentence or paragraph by new text.

(C) Check the spelling: You can check spelling of the typed text

3. Formatting: After editing, you should format the text. using the Tool menu. Formatting is setting the font of character, margins of paragraph, page size. Using formatting tool, your document is looking good. You can add the graphic according your need.
4. Saving: You have to follow the given steps to save the text permanently on the hard disk.(unit 3 computer based business applications word processing bcom notes)

(i) Click on the Save or Save As option in File menu.

(ii) A dialog box is displayed on the screen. Type the file name in File Name box.

(iii) Click on the Save button.

5. Printing a Document: By default, Word prints one copy of the entire active document. You can, however, choose to print the current page only, multiple pages, multiple copies, or selected text.(unit 3 computer based business applications word processing bcom notes) You can also print to a document rather than to a printer, or print non-document items such as Summary Info.

Moving and Copying Text

Another of Word’s power editing features is its ability to move and copy text within a document. You can, for example, quickly and easily move a table of numbers from the top of the fifth page of a business report to the bottom of the 11th page, or copy a four-line address to several different locations within the body of a letter.

(unit 3 computer based business applications word processing bcom notes)

The Clipboard: Windows provides a temporary storage are called the Clipboard for those times when you move or copy text. When selected text is cut (removed) or copied, it is placed on the Clipboard. Pasting inserts a copy of the Clipboard contents before the insertion point.

Moving Text: To move text within a document:

• Select the text to be moved.
• Choose Edit, Cut to cut the selected text from the document and place it on the Clipboard.
• Place the insertion point where you want to move the text.(unit 3 computer based business applications word processing bcom notes)
• Choose Edit, Paste (or click on the Paste button) to paste the cut text before the insertion point.

Copying Text: To copy text within a document:

• Select the text to be copied.
• Choose Edit, Copy to copy the selected text to the Clipboard

Place the insertion point where you want to copy this text. Choose Edit, Paste (or click on the Paste button) to paste the Clipboard text before the insertion point.

Text Formatting in Word: After typing and editing, we can format the text to make the document attractive. Setting the page margin, alignment of text, determination of proper size, style of font, selection of colour are including in formatting.(unit 3 computer based business applications word processing bcom notes)

Alignment

The setting of text according to left or right margin is known as Alignment. It arrange the text properly on page. There are the four type of alignment in MS-Word.

1. Centre Align: Select the text which you want to align. Now click on the Center Align tool. Text will be set on centre.
2. Left Align: Select the text which you want to align. Now click on the Left Align tool. Text will be set on left. This is a default type of alignment.
3. Right Align: Select the text which you want to align. Now click on the Right Align tool. Text will be set on right.(unit 3 computer based business applications word processing bcom notes)
4. Justification: Select the text which you want to justified. Now click on the justification tool. Word increases the spacing between words in the selected paragraph to fill each line (except the last line. which is too short) so that the text is even with both the left and right indents.

Border and Shading

We can do make border and shading around the text.

1. Borders: The task of making the border around the whole page or paragraph in word is easy task. We select text for border. Now click on Border tool on Formatting toolbar, around the text a border will make.(unit 3 computer based business applications word processing bcom notes)
2. Shading: We can make word document attractive and effective using various shades. Select the text for shading. Now click on Shade button, a drop down list will be displayed on the screen. Now click on desired colour. If you want to remove the shade, click on None in the drop down list.

LOTUS 1-2-3

Lotus 1-2-3 is an integrated electronic worksheet (spreadsheet) program developed by MITCHELL KAPOR, founder of Lotus development corporation, USA. It let you create your own worksheet and enter information. It perform all kinds of calculation and displays results on the screen.

unit 3 computer based business applications word processing bcom notes

MS-Excel

An electronic worksheet (or spreadsheet) is used to store information in the memory of a computer, ask the computer to calculate results, and display information and results on the computer screen in a desired manner.(unit 3 computer based business applications word processing bcom notes) In other words, it replaces the normal paper sheet or ledger, pencil (or pen), eraser and calculator. In such a worksheet, information is entered through the keyboard and displayed on the screen.

The information already entered in the worksheet can be changed easily. The worksheet calculates results; for instance, it can work out the total sales by multiplying the quantity sold with the unit price.(unit 3 computer based business applications word processing bcom notes) If some information is altered, the worksheet automatically recalculates the results, e.g. if the unit price is changed, it automatically recalculates and displays the new total sales figure. The information entered in the worksheet can also be printed.

Starting MS-Excel

To start Microsoft Excel, you have to follow these steps:

1. Click on the Start button in the windows environment.
2. Select All programs option from the Start menu.(unit 3 computer based business applications word processing bcom notes)

unit 3 computer based business applications word processing bcom notes

For inserting a sheet: Select a sheet (before which a new sheet has to be inserted) by clicking the sheet tab and choosing the Insert, Worksheet command.

A new worksheet is therefore and becomes the active sheet. To insert several sheets at once the user can select the number of sheets to be inserted and then choose the Insert, Worksheet command.

(v) Rename the Worksheet: To rename worksheet, you have to follow these steps:

1. Double-clicking the tab of the sheet to be renamed.
2. Type the new name (upto 31 chars) in the dialog box,
3. The new name appears on the sheet tab.

unit 3 computer based business applications word processing bcom notes

(vi) Move or copy worksheet: Sheets in the workbook can be re-arranged by moving them. Sheets can be moved within the workbook or to another workbook.

Cell Reference

Before we start performing mathematical operations on our data, we need to know the method of instructing the computer to calculate different functions. We need to put these instructions in specific cells and is known as the cell addressing method. There are different “methods to use the cell address depending on the kind of calculations that are needed.

1. Relative address,
2. Absolute address,
3. Mixed address
4. Relative Address Method: In this address system, we refer to the cells without fixing either the columns or the rows. These are refrences to cell relative to the position of the formula.(unit 3 computer based business applications word processing bcom notes) When you copy a formula that uses relative references, MS-Excel automatically adjusts the references in the pasted formula to refer to different cells relative to the position of the formula.
5. Absolute Address Method: It is also called absolute references, which are cell references that always refer to cells in a specific location. If a dollar sign precedes the letter and/or number, such as $A$1, the column and/or row reference is absolute, In this method, cell address does not change in a formula even if you copy it to other cells. For cell address fixing, we have to use $ sign before row and column number.
6. Mixed Address Method: It is combination of both relative and absolute addresses. Every cell address has two co-ordinates. One is column and other is row. Mixed address has one absolute coordinate and one relative coordinate. You can fix either the column or the row. Once you copy the formula at another place, the address changes accordingly. (unit 3 computer based business applications word processing bcom notes)The absolute value remains unchanged while the relative ones change. If you want to change only the column in any calculation, you have to use mixed address method.

FUNCTIONS

These are in-built formulas that perform calculations by using arguments. Arguments are values which we use in functions. There are many categories of functions. We will discuss them one by one.

unit 3 computer based business applications word processing bcom notes

1. Mathematical and Trignometrical Functions

These functions perform mathematical operations. Some commonly used mathematical functions are given below.

ABS (Number): It returns the absolute value of number.

EXP (Number): It returns e raised to the power of number.

FACT (Number): It returns the factorial of a number.

unit 3 computer based business applications word processing bcom notes

SECOND (Serial Number Or “Time”): It returns the second of a time value. The second is given as an integer in the range 0 to 59.

Goal Seek and Solver

The real power in Excel comes in its ability to perform multiple mathematical calculations for you. One of the tools in Excel that you can use to perform these calculations is a Data tool called What-l Analysis.(unit 3 computer based business applications word processing bcom notes) What-If analysis allows you to see the effect that different values have in formulas. Have you ever thought, “What interest rate do I need to qualify for to have a car payment of $400 on the car I want? This question can be answered using What-If Analysis.

There are three What-If analysis tools that you can use. To access these, select the Data tab, and locate the What-If Analysis command. If you click this command, a menu with three options appears.(unit 3 computer based business applications word processing bcom notes) Goal seek is useful if you know the needed result, but need to find the input value that will give you the desired result. In this example, we know the desired result (a $400 monthly payment), and are seeking the input value (the interest rate).

Goal Seek

To use Goal Seek to Determine an Interest Rate:

Select the Data tab.

unit 3 computer based business applications word processing bcom notes

Locate the Data Tools group.

Click the What-If Analysis command. A list of three options appears.

Select Goal Seek. A small dialog box appears.

Select the cell that you want to set to a specific value. In this example, we want to set B5, the Payment cell.

Insert the cursor in the next field.

Enter a value in the value field. In this example, type-$400. Since we’re making a payment that will be subtracted from our loan amount, we have to enter the payment as a negative number.

unit 3 computer based business applications word processing bcom notes

Insert the cursor in the next field.

Select the cell that you want to change. This will be the cell that tries various input values. In this example, select cell B4, which is the interest rate. Click OK.

Then, click OK again. The interest rate appears in the cell. This indicates that a 7% interest rate will give us a $400 a month payment on a $20,000 loan that is paid off over 5 years, or 60 months.

Solver

The Goal Seek command is handy for problems that involve an exact target value that depends on a single unknown value. For problems that are more complex, you should use the Solver add-in.(unit 3 computer based business applications word processing bcom notes) The Solver can handle problems that involve many variable cells and can help you find combinations of variables that maximize or minimize a target cell. It also specifies one or more constraints-conditions that must be met for the solution to be valid.

The Solver is an add-in. If the Solver button does not appear on the Data tab on the Ribbon, click the Microsoft Office Button, Excel Options, Add-Ins category, and then click the Go button. Then select the Solver Add-In check box, and click OK to install it. Click Yes to confirm that you want to install the Solver add-in.

5. Multiple Price Levels: It allows you to pre-define item rates for specific categories of customers, enabling faster and error-free invoicing and data entry.

DBMS

A database is an integrated collection of logically related records and files. It consolidates records previously stored in independent files so that it serves as a common pool of data to be accessed by many different application programs.

Definitions of DBMS: According to Holden Paule, E. “A DBMS is the tool that computer use to achieve the processing and orderly storage of data.”

Relational Database

Relational Database is a such type of database which are based on relational model.(unit 3 computer based business applications word processing bcom notes) According this model data will be stored in various tables. We need attributes for formation of tables. These attributes is known as field. Data is stores as records in every table. Record is called as Tuple.

For Example: If we store following data of student of a class, we can represented Student table following types:

Roll No.	Name	Age	Percentage	Position in Class
105	Prakash	20	82	4th
106	Suresh	19	80	3rd

If we divide table (Relation) into rows and columns, a row of table is known as a record or tuple and a column of table is known as attribute.

The total number of attributes or field is known as degree of the table. (unit 3 computer based business applications word processing bcom notes) For example-The degree of ” Student Table” is five. Total

number of row of table is Cardinality. If any table has ten rows, cardinality will be 10.

Keys: A key is a table-column used to identify some required rows from a table.(unit 3 computer based business applications word processing bcom notes)

Super Key: An Attribute (or combination of attributes) that uniquely identifies each entity in a table.

Candidate Key: A minimal super key. A candidate key may be described as a super key without the redundancies and that does not contain a subset of attributes that is itself is a super key,

Primary Key: A candidate key selected to uniquely identify all the other attributes values in any given row and cannot contain null entries. For example Roll No. can be a primary key in Student table. Primary key should be unique.

Secondary Key: An Attribute (or combination of attributes) used strictly for data retrieval purposes.

Foreign Key: An Attribute (or combination of attribute) in one table whose values must either match the primary key in another table or be null. Foreign key is used to make the relation between two tables.

Meaning of RDBMS

A relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model as introduced by E.F. Codd. Most popular commercial and open source database currently in use are based on the relational database model.

RDBMS data is structured in database tables, fields and records. Each RDBMS table consists of database table rows. Each database table row consists of one or more database table fields.(unit 3 computer based business applications word processing bcom notes)

RDBMS store the data into collection of tables, which might be related by common fields (database table columns). RDBMS also provide relational operators to manipulate the data stored into the database tables. Most RDBMS use SQL as database query language.

Microsoft Access

Microsoft Access is a powerful window based Relational Database Management System. With Microsoft Access yo can easily:

Create a wide variety of both stand-alone tables and databases Add to or edit databases by filling in the blanks.(unit 3 computer based business applications word processing bcom notes) Search for and display information in many formats.Generate printed reports and mailing labels in a variety of formats and sizes automatically perform mathematical calculations on numerical data in your database incorporate the results of calculations in printed reports and store the results for future use in applications such as balance sheets

Creating A Database

In Access, the first step is to create a database. It will contain all data-tables and other information related to an application. A Microsoft Access database can contain six types of objects.

They are:

Tables that store data

Queries that extract from one or more tables

Forms that display data from tables or queries

Reports that summarize and present data from tables and queries

Macros that help you to automate frequently used steps

Modules that store Access Basic program code, the programming language supported by MS Access

All databases in Access have an extension.(unit 3 computer based business applications word processing bcom notes) MDB. Even if you create a single table with no other objects with it, you have to create an .MDB, file.

To create a database:

Click on the New Database option in the File Menu. Or

Click on the first button in the tool bar.

The New database dialog box appears. Type in the database name. The Database Window appears.
