Defining data structures


For building add-ons upon existing applications, it is possible to develop using an existing database. If a new project is started, it is recommended to define data structures in Java syntax and generate an arbitrary database out of these database neutral instructions.


See samples like e.g. de.jugs.cookbook.DoCookbook. Each of these DataObject extending classes represents a table in the database. Class mkt.TableCreator is a sample for how to create tables dynamically when an empty database is found. It is extending de.must.dataobj.TableCreatorStd.
Class de.jugs.cookbook.DbScriptCreator is a sample for how to create a script to create a MySQL dialect.

However this is done, the principal is to define the database inside the application and then use it freely and expandable.

Attribute types (column types)

See Index and IndexItem for how to define indices.
