O2DBI - Introduction - O2DBI Features
-> Back to Overview page <-
Database connectivity:
- backend modules for different database management systems (MySQL, PostgreSQL)
- generated code is independent of database system
Class design:
- arbitary complex class hierarchies (e.g. currently upto 7 levels of inheritence in EMMAWiki)
- support for different scalar datatypes (integral types, floats, boolean, strings etc.)
- support for associations between classes
- support for persistent array and hash valued attributes
- nesting of arrays and hashes for complex attributes
Generated code:
- central master module for propagating method invocations to the right class
- polymorphic queries
- object cache for faster object lookups
Extensions:
- each class may be extended with its own business methods
- extensions are inherited in the class hierarchie
Interoperability:
- multiple masters (and thus multiple databases) may be used in parallel
- different generated hierarchies can be used at the same time, no namespace clashes
