Lesson 7

Databound Controls Conclusion

This module discussed how easy it is to add, remove, and modify data using the Recordset and data bound Design Time Controls within the context of database web applications.
Using these tools you can add functionality to your Web site simply by dropping them into a page, setting a few properties, and adding event handlers. You can also access the Data Environment object by using script. This allows you to customize and create smaller pages that could also have a custom interface.

Key concepts

  1. Recordset objects and Design Time Controls have built-in methods that can add functionality to your Web site without having to use SQL statements. These methods allow you to insert, modify, and delete records in a database.
  2. Although most scripting languages have some form of data conversion capability, it's important to make sure that the database and scripting data types match.
  3. Instead of using Visual InterDev's Design Time Controls, you can write your own script to add functionality to your Web site. This is particularly helpful when you want to create a custom interface.

Glossary

This module introduced you to the following terms:
  1. data type: A variable or field attribute that specifies the kind of data it can hold.
  2. floating point data type: A single precision number containing a sign bit and a 23-bit mantissa.
  3. subtype: The different data types represented by the variant type.
  4. variant: The data type for all variables that aren\'t explicitly declared as a specific type.
  5. PageObject: A script object that lets you treat active server pages as an object.
In the next module you will learn how to script with databases.
