Features
~~~~~~~~

- Easy to use
- No configuration necessary.
- Small library size.
- Supports PostgreSQL, MySQL, Oracle, HSQLDB
- Own straight-forward, simple query language
- Supports transactions
- Supports polymorphism (selecting for superclass will return all subclasses too)
- Can save any bean (does not use Serializable/Externalizable stuff)
- Transparent handling of references to other beans
- Can handle circular-, or self-references
- Can save Lists and Maps
- View selects
- All queries are now transactions safe, no matter what you do,
  result lists stay the same.
- Distributed, scalable operation.
- Dynamic object (classes and attributes)

Wishlist/TODO
~~~~~~~~~~~~~

- Support H2DB, DB2.
- Support for all primitive array types
- Support for primitive values inside lists (wrappers?)
- Transaction and connection leak detection
- Make history retention configurable! (up to seconds)
- Performance/monitoring with a separate client (pretty graphs and such)
- Performance enhancements:
  - Implement List indexOf() as a single select, not as iteration
  - Implement List remove(obj) without indexOf(), just remember the persistence_id,
    and based on that, one can compute the index of any real object.
  - Do not create all indexes, just those, which were referred to in selects
  - Remember, if a table has no modifications (only new rows, like a log table),
    and do not generate time controls to those tables.
  - Remove persistence_ids table, and make the classname part of the key,
    this way, persistence_ids will not have to be joined to each query,
    and each table can have it's own ids.
- Make new TX_EMBEDDED transaction which sees the parents modifictations
  just commits separately
- Schema evolution help (for example: give the value of a new attribute, then
  set this for all versions of objects). Abstract versions from migration
  scripts, automatically adapt changes (somehow) to all versions of objects.
- Max and min memory of cache configurable
- Scripts: data snapshot
- Aggregate functions (sum, count, etc.)
- Subselects
- CrystalReport / OpenReport / JaperReposts integration
- Allow for similar attributes in classes, and select those separately,
  or name those attribute while selecting!
