Database file mapping names to records, implementing a file-system

There are no data size limits other than the range of a 64-bit signed integer. Scalability is limited to 1 - 10 Mio. entries due to non-paging internal structures.
elementary database files for Java, B+ tree index files, ISAM
Java API to realize quick ISAM (Index Sequential Access Method) functionality for application in the file system. Includes scalable database files w/ space recovery and variable record length, scalable B+Tree index files. Supports file backup and restore. Two package types: one with and one without strong file encryption using Twofish algorithm and state-of-the-art encryption technology.
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)
SimpleSQL is a 64-bit relational database, works as a standalone server-free db. component and transactional db. server, with standard SQL and JDBC, has portable single db. file, first db. available in Java and C++.
