One Approch to DDL abstraction.

I've been playing with DDL abstraction for Drupal. My current idea is to mimic the SQL-92 syntactical structure as an array. I'm working on the assumption that the generic SQL-92 clause ordering is consistent it is only the clauses themselves that need to be translated. I am going to assume that we use mysql datatypes by default so the values in the data definition array will be familar to mysql users.

Eventually I would like to expand this to support relationships and database introspection.

Gathering momentum

Hi Darrel, we met at OSCMS last week. I am also working on these ideas; see my article at http://jaspan.com/schema-project-database-abstraction-reflection-and-mig....

Since writing it, I've changed the array structure; it is now based on (okay, ripped off from) CCK's "database columns" format. My code already supports database introspection and verifies the combined schema DDL from all modules that implemenmt hook_schema against the live database, reporting missing or inconsistent tables. I also can construct MySQL CREATE TABLE statements from the schema structure. Since I have introspection, it is trivial for me to construct the schema array for all system tables automatically, so I have. Creating it for CCK types should be easy too.

I also see a very short and easy path to using the schema structure to be able to load all fields of a node (including CCK nodes, possibly even with multiples) in a single SQL query from within node_load. This will cut storage requirements by eliminating the need for CCK's fields cache table and reduce the number of queries by at least one (no field cache load) for every node load.

So, we need to talk. :-)
