Databases

Databases come in many different flavors and serve many purposes. The information they contain is limited only to the imaginations of the people who design them. Not surprisingly, therefore, applications which use databases are equally diverse.

In general, however, the idea behind web-based applications is to enable users access to the most up-to-date information available at a given moment, in a form that is most useful to them. Sometimes this means the users themselves are allowed to add or update records in the database. More often it means that users are given the opportunity to browse the contents of the database based on their own search criteria.

In this page we take a look at a sample guestbook to show how easily such applications can be created using RADpage. The following list shows some of the records from that guestbook. If you like, you can click the underlined link next to any record to Edit its contents.

Alternatively, you can click any of the highlighted component handles surrounding the table headers ("Guest_Name", "Email", etc.). Doing so will display the contents of that field in the RADpage window and you can change the column heading or formatting attributes of that field.

The database table is constructed using two main components dbdisplay (outer brown handles) and dbformat (inner brown handles). dbdisplay controls the database query. For example you can change the number of records to display. The dbformat controls how the table is formatted. For example you can change the table's background color.
