Hi

I wanted to inform the tasks I worked on this week: Dec 26 - Dec 31

* Develop the Datastore methods: getSchemaName, createSchema, deleteSchema,
schemaExists
* Enable tests in Neo4jStoreTest : testCreateSchema ,  testSchemaExists
* Enhance the implementation of the connection to the backend.
* Write a blog about my project.

You can find my code in my branch:

https://github.com/mgov88/gora/tree/GORA-663

Best Regards,
Gaby
