A java databass.
BSEditor: HeliDB is a database for persisting key鈥攙alue pairs from a Java program. Users have many choices in configuring what capabilities they want the database to have and in how the data is stored. In its simplest configuration, HeliDB is just a file-backed Map. More advanced configurations support transactions and fast searches and inserts through using B+ Trees.

Notable features are:

* The HeliDB Database interface extends Javas Map, so a HeliDB database can be used as a drop-in replacement for a Map.
*
* The Database interface defines methods that are more efficient for working with persistent data than the methods from Map.
* A database can be configured to support transactions.
* Database operations can be made FASTER by indexing data in B+ Trees.
* Database object creation is fast, so clients can Create new databases as necessary without having to worry about performance.
* The database runs in the same process as the Java program which makes database calls just local function calls. (i.e. fast) you can free download HeliDB for Linux 1.1.1 now.
