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 El mié, 30 de dic. de 2020 a la(s) 13:28, John Mora (jhnmora...@gmail.com) escribió: > Hi > > Thanks for your report. > > The Utils package is specific for each datastore; it is not mandatory.
