This page details out the data model that exists in the database to back the object model.
Notes
- I've written a basic CRUD test so I know that it can insert and delete trees of objects. Beyond that we'll have to work things out.
- At this point there is NO business logic implemented. If a transaction breaks some database rule, for example, trying to insert a ConsumableAmount without a ConsumableType, an Exception will be thrown.
- Collections are lazy loaded but I haven't written any unit tests to verify that they're working.
- I had some issues with the ConsumableAmount table. It's a many-to-many join table with an extra column for storing a value. JPA hates that. (You have to have the primary keys for both the ConsumableType and PhaseType BEFORE inserting the ConsumableAmount; so ConsumableAmount would've need to be handled is separate transactions.) The workaround was to add an id column; it's not pretty but it works.
- All testing has been done against FOG. Is this copacetic or should I start setting up MySQL for developing against?
- All transactions are currently handled through a single EAO object.
- The ESP-DAL (<- Data Access Layer) build uses Maven 2. A dependency graph is available at here
