Moelnir is a basic database file, addressing variable record data through
integer identifiers, which applies heap organisation of its data space.
Advantage of Moelnir is that each record is stored in a continuous
segment on the file while still record size is limit-less variable
and modifiable. There are no data length limits other than the range of a
63-bit unsigned integer. Scalability is limited to 1 - 10 Mio. entries due to
non-paging internal structures.
Java Objects Persistence Service (JOPS) is a simple and very useful library dedicated to developers who don't need all the power of traditional DBs (MySQL,Oracle.etc) but still need to be able to persist and manipulate their persisted objects easily
2 Java frameworks with transient and persistent object models based on nonstandard approach (less evident but faster development): an object is a set of named fields. 3 non-object libraries simplifying access to tables stored in RDB, text files, etc.
XTEA (eXtended Tiny Encryption Algorithm) support for db4o open source object database. XTEA is a block cipher that operates on a 64-bit block size with a 128-bit key. An extremely tiny but very fast encryption algorithm (with cycles less than 32 rounds)
Persitancy api simaler to Prevailer but with more transparancy and less intrusiv to how you can disign your data structure. It uses a bytecode enhancer to add needed code to have your object presited betwhen sessions.
This project tries to define a new grammar to be used for database access. It should be easier to learn, understand and use than SQL, be more consistent, and contain significantly less rules. It does not try to be an extension or subset of SQL.
J2EE based database access; an alternative to Entity EJBs that allows for much higher performance, easier use, less coding, more dynamic, and more tuned to use with a web presentation layer (such as Tapestry).
