-# Welcome
-
-SikevaDB is a Simple KEy VAlue DataBase.
-
-Features:
-* double key value
-* single session only
-* connector to file persistence
-* connector to SQL persistence
-
-Why build a single session database? Because, in so many cases, I need a single session only in my application.
-
-Actually, the following backends are supported:
-* file system
-* MySQL Database
-* HSQL Database
-
-# LICENSE

-SikevaDB is released under the GNU AGPL license. Enjoy!
