Before you build the application, you must create a database in which to store the information for the subscribers. In this section you will install ODBC drivers for Microsoft Access, build an Access database, and create an ODBC datasource for use with the project. You need to understand ODBC datasources if you want to develop Internet applications. A thorough understanding of the subject will allow you to access any ODBC back-end data storage element. For example, if you choose to use a Microsoft SQL Server database instead of a Microsoft Access database, ODBC will be able to work with it equally well. Although Access databases are fine for demonstration purposes, they are not useful for handling high-traffic web sites with many transactions. However, the techniques you will employ to interact with an Access database are the same ones you would use for any ODBC datasource, including a SQL Server datasource.
