Defining Entities and Models
The Magentrix Online Database provides the ability to generate persistable data models that are stored and indexed into the Magentrix Cloud Database. Custom Data Models can also be created using Magentrix Active Classes to perform special or customized application logics. A Data Model is a class with properties that can be used as holding container for data. Moreover, you can use the Data Model to specify Metadata, used to describe the properties of the Models that was not easily achievable by other means. Magentrix implements most Data Annotations supported by Microsoft, and the following Annotations can be used to further customize the Data Model's Metadata in order to control the presentation and data validation aspects of your Models.
