Objects within a particular group in the VDB can be thought of as a table of data. Although group data is not stored as an actual table, it can help to understand groups within the VDB using a table such as the one below:

This example table contains a heading row and three rows of data. You can think of each data row as an object in the VDB group. Therefore, in this example there are three objects in the group. Each object consists of attributes which are represented by the columns in the table. The heading row names the attributes. In this example the attributes of each object are “ename” (for the Employee Name), “phone,” “department,” and “title.”

In addition to general data groups like the one described in this example, Info*Engine maintains several context groups whose attributes and values are available to all webjects. The context groups contain special information such as the HTTP protocol and HTML form data attributes and values that are retrieved by Info*Engine. For more information, see Context Groups.
