Application Model Overview : The Data Model

The Data Model
The Data Model provides a logical description of the data in a particular data source. The data source is a named connection to a specific database. ActiveGrid Applications use a Data Model based on the XML schema standard. The Data Model files in your application end with the .xsd suffix.
ActiveGrid’s Data Model uses complex types to represent the tables in a relational database. A complex type is a data structure that can contain multiple elements, each with its own data type. Complex types are part of the XML Schema standard. Each element in a complex type can itself be a simple type (representing a column in the table) or a complex type (representing a relationship to another complex type).
Forward and Reverse Engineering
The ActiveGrid Studio can build a Data Model for you automatically by importing schema information from a database. Alternatively, you can build a new Data Model in the ActiveGrid Studio and then export it to create tables in a database. You can also evolve the database with changes from the Data Model and, conversely, you can update the Data Model with changes from the database.
