    This tutorial will help you get started with Microsoft Access and may solve some of your problems, but it is a very good idea to use the Help Files that come with Microsoft Access, or go to Microsoft's web site located at http://microsoft.com/office/access/default.htm

    First of all you need to understand how Microsoft Access breaks down a database. Some keywords involved in this process are: Database File, Table, Record, Field, Data-type. Here is the Hierarchy that Microsoft Access uses in breaking down a database. for further assistance.

Create a database using the Database Wizard

    click Access Database Wizards, pages, and projects and then click OK.

    If you have already opened a database or closed the dialog box that displays when Microsoft Access starts up, click New Database on the
    toolbar.

  2. On the Databases tab, double-click the icon for the kind of database you want to create.

  3. Specify a name and location for the database.

  4. Click Create to start defining your new database



Create a database without using the Database Wizard


  1. When Microsoft Access first starts up, a dialog box is automatically displayed with options to create a new database or open an existing one. If this dialog box is displayed, click Blank Access Database, and then click OK.

    If you have already opened a database or closed the dialog box that displays when Microsoft Access starts up, click New Database on the toolbar, and then double-click the Blank Database icon on the General tab.

  2. Specify a name and location for the database and click Create. (Below is the screen that shows up following this step)

Tables

A table is a collection of data about a specific topic, such as students or contacts. Using a separate table for each topic means that you store that data only once, which makes your database more efficient, and reduces data-entry errors.
