Source code architecture
The DAL source code generated by ODS is divided into three distinct areas: the data store, data structures and the data store providers. They can be compiled into the same or separate binaries.
The Data Store Providers
The data store providers are the only part of the DAL that actually communicate with databases. Each data store provider is responsible for executing stored procedures and SQL and creating and upgrading databases of a particular database (data store) type, such as SQL Server or MySQL. All providers implement the same interface, allowing the rest of the DAL to be completely database agnostic.
Data Structures
The data structures are a series of classes use to hold data from objects stored in the database. The data structures classes are used purely to pass object data around within the DAL.
The Data Store
The data store is the visible front end for the DAL and it is what your application will interact with. It contains a class for each class that you designed in ODS Design Studio. Each class provides accessors for all the properties and all the get, add, update and delete methods that you defined in ODS Design Studio.
