This library contains functions for working with MySQL database (I didn't give attention to other RDBMS as I work almost only with MySQL, but if there will be need for other database wrappers, I made it easy to extend it for other database types), hash (which drastically speeds up data search, but note - it is not a container - it is just indexer and searching mechanism), and connection pool.
Some may ask - what for have I wrote mysql wrapper functions? I've created wrapper for MySQL because native mysql functions in my opinion are not very convenient to use.
