   Introduction 
  This is the javadoc for Gora. This javadoc captures all of the modules in Gora.

   Gora Modules 
   Gora source code is organized in a modular architecture. The gora-core module is the main module which contains the core of the code.
  All other modules depend on the gora-core module. Each data store backend in Gora resides in it's own module. The documentation for the specific module 
  can be found at the module's documentation directory.

     gora/<module-name>/src/test/java: Unit test codes in Java  
     gora/<module-name>/src/test/avro: Avro schema definitions used in unit tests
