Initial version of Data Manager utility library is now released and available in Maven central repository. This is my second open source project released under relaysoft.net domain. Library contains ready services for data management with in-memory and file system based storage options. In addition it provides abstraction layer on top of which it is easy to implement data manager which support storage solution for your needs. E.g. database or cloud storage based data managers. Along with Data Manager library I also release separate starter project for the Spring Boot users which provides data service as auto configured Spring component.
