Before you being to design and develop a database,you should do some planning. Consider what datayou will include and what information you want tocreate


7/65

Database structureTo use Access effectively, you first need to understandsome basic terminology. In access, a database canconsist of one table or a collection of tables.


8/65

a table is composed of columns and rows, referredto as fields and records in Access


9/65

The rowsThe rows in the table are call records.Each record is a group of related fields, such as all ofthe information regarding each member in amembership database or each customer in acustomer table.


10/65

The columnsthe columns in the table are called fields.Each filed contains a specific piece of informationwithin a record.


11/65

The primary keyWhich is assigned to a field, uniquely identifies eachrecords in a table. it tells the database program howyour records will be stored, and it prevents duplicateentries


12/65


13/65

Using the data stored in the table, you canuse Access to create the following objects:queries, forms, and reports. The databaseprogram searches for and retrievesinformation from a table or tables to answerthe question. AlI of these objects tables,

forms, and stored in single file, which is thedatabase.

ADDING RECORDS TO A TABLE


34/65


Creating and saving a table is the first step ina two-step process. The next step is topopulate or add records to the table. Whenadding or editing record in a table, you can

create a form or use datasheet view. Vieware formats used to display and work with thevarious objects. Access contains two basicview:



35/65


Design view: used to create a table, form, query, andreport.



36/65


Datasheet view: displays a row-and-column view of thedata in tables, form, and queries; the cable is calleddatasheet.

You can switch between view by clicking the view button


37/65

You can switch between view by clicking the view buttonarrow on the toolbar.

When data is entered is a cell, it is called an entry. To movefrom one cell to another, you can use the mouse to click ina cell or you can use the keyboard to navigate in a table.

You learn how to create and use a form to add records later

You learn how to create and use a form to add records laterin this lesson. You use datasheet view to enter. You usedatasheet view to enter record in the table.1. Click the first empty cell (the first name field), and type

Mary. Notice that as you enter the text, accessautomatically assign the primary key1 in the contact ID field.

2 Press tab to move from field and complete the

PRINTING A TABLE


42/65

PRINTING A TABLEYou can print the table from Datasheet view.To print the table in landscape mode ( inwhich the lines of the text are parallel to thelong dimension of the page), select pagesetup on the file menu to display the pagesetup dialog box. Click the page tab andthen click the landscape option button. Clickthe OK button to close he dialog box.

Click file on the menu bar and then clickprint to display the printDialog box, you have a choice of printing all

records or selected records.

SORTING A TABLE


44/65

SORTING A TABLE

The data in table can be sorted in ascendingor descending order. In descending order,the record are sorted from A to Z, or smallestto largest. In descending order, the recordsare sorted from Z to A, or largest to smallest.In datasheet view, click the field name thatyou want sorted; the column is highlighted.

Click the sort ascending or sort descendingbutton on the datasheet


45/65

Toolbar. You may sort on any field. The last name field is


46/65

y yhighlighted so the data will be sorted according to thatfield.

Table navigationQuite often data changes after it is entered in adatabase. For example, one of your customerschanges their address or phone number or you want toadd a new customer to the database. Access providesa navigation toolbar that makes it easy for you to movefrom record to record or locate a particular record in atable.The navigation buttons that are displayed at thebottom of a table in datasheet view. These navigationbuttons are especially useful when you are working in alarge database with hundreds or even thousand ofrecords.


47/65

MODIFYING A TABLE STRUCTURE


48/65


After you have created a table, you canmodify it by adding and deleting column(fields) and rows (records). When you deletea column or a row from the table, all the

data contained in the column or row isdeleted from the database. Delete columnor rows from a table when they are no longerneeded to store data. You can. You

add/delete rows and column in datasheetview.If necessary, click the arrow on the viewbutton and select datasheet view.

The sample tablets that you can access through theTable Wizard are an excellent tool to help you getstarted and understand the different views andfeatures in Access. These tables, however, might not

necessarily fit your needs.

DATABASE DEVELOPER


53/65

A database developer writes and modifies database. Data in adatabase can be reorganized, dispersed, and accessed in several ways.Databases are important to companies and organizations becausethey contain record or files, such as sales transactions, productcatalogs and inventories, and customer profiles.

These individuals must be good at communicating not only incomputer languages, but with people as well. They write descriptionsabout programs, prepare manuals, create help screens, and explainnew systems to users. In addition to excellent communication skills,they must have extensive experience with hardware, software, andsystems and processes.

To become a database developer, an individual should have abachelor of science degree in computer science, as well as specificcomputer certifications. Prior experience also is recommended. Thesalary for this position will vary depending on the location and sizeof the organization and an individuals experience

Forms


54/65

Forms In addition to adding and viewing records in

Datasheet view, you also can create anduse a data-entry form. A form provides aconvenient way to enter and view recordsin a table. When you create a form, youcreate a form, you are adding a new objectto the database

Entering and Editing Data in a Form


61/65

Entering data in a form is similar to entering data in a tablein Datasheet view. You use the same keys to move theinsertion point among the fields. Furthermore, the samenavigation buttons are available at the bottom of the form.To add a new record, click the new ( blank) record button.To edit an existing record, use the navigation keys to displaythe record and make the changes in the fields on the form.Complete step-by-step 13.5 to add a new record to thedatabase
