- **speedment** - cool-looking streaming API, but it's way of from common SQL-like syntax & failes to work with UUID columns corectly, also they wanna' our money, dude if we need something not straightly mapped. Out of competition.

#### Honorable mentioning
- EJB 4.0 (now stands for Jakarta Enterprise Beans) is supported only in GlassFish 6 which is a part of Eclipse Foundation family. It's not included in research due to high binding to one particular implimentation with low chance of change in future.
- EOF (Enterprise Objects Framework) is a part of Apple now (originaly designed in NeXT). It supports java from back in a days, but now it's obsolete as of April 2005 (rise of Objective-C and Mac OS Tiger Intel-epoch)
- Oracle Kodo - JPA-based framework from Oracle, does not compete due to Oracle involvment and price tag.
- Oracle TopLink - part of Oracles' Fusion Middleware, was donated to Eclipse Foundation in 2007, and renamed to EclipseLink, so TopLink is obsolete now.
