Today I have a time to upgrade DBX engine thats is a part of RevolveR CMS to version 1.1.1. All changes I was integrate to CMS core are ported to different and independednt version of Data Base X.
By default for now DBX allows you not only execute DB queries from structure based arrays, for now it is allows you use files based on hash tables cache. Added new and more simple queries like Inject with witch you can use one instruction for intellectual INSERT or auto UPDATE.
For examples please see revolver core or distro index.php page contains examples and unit test info. All of it very simple to learn.
DBX v.1.1.1 availible from github here: https://github.com/xShiftx/Revolver_DBX.
