Maven 0.3.5 Beta
Category : Technology/Maven0dot3dot5.txt
Maven now has the ability to create tables, delete tables, and add new table columns (for SQLite3, PostgreSQL 8.x and MySQL 5 databases).
It can also now delete and modify table columns (only for PostgreSQL 8.x and MySQL 5 because you can't delete table columns in SQLite).
Three more steps, and I'll be able to get Maven to where I want it to be :
1) create databases from scratch, 2) allow drag and drop of data and table structures between the three supported databases, and 3) to support a broadening of the things we can specify on the table structures - e.g., foreign keys, default values, and especially various types of constraints.
Then Maven will start to get useful.
If I can do that, then I can keep Luca focused solely on accounting (and take away all those database management functions) because the user can use Maven to move the data across any of the supported databases.
Also, Luca can just restrict itself to providing the standard accounting reports and, hopefully, I can develop Maven so that the user can do all sorts of ad-hoc analytical reporting on it.
That, at least, is where I'm hoping to go with these two projects.
If I can use Maven to help me design and organise the data structures quickly, then I might be able to work faster on the applications I plan to overlay on top of Luca from next year, e.g., inventory, invoicing, time billing, etc...
