This REST based DB application is covered by General public license v3 and it is intended to be used for demo purposes only. The project can be used by any organization provided the author name (Arun Nallan) and GitHub URL is included in the comments section of the imported code.
- Its just a plain demo purpose to demonstrate Graph database with linear operation. Time is not spent enough for performance optimization like search operations - however, best effort is made.
- All queries are case sensitive.
- Since this is a REST application - it uses error codes like 400 for bad request, 404 for resource not found and 200 for success, etc., following the standard convention.
- At this time, the application does not support BULK Import/Export but can be easily extended to serialize/de-serialize the in-memory database from/to JSON file
