The following scenario has been addressed on Chegg previously, however the answers were somewhat incomplete and lacking references. Can you please answer these questions in a more detailed manner covering all the bases of the scenario?, Thank You.

Scenario:

"TAL Distributors is interested in open source distributed database management systems (DDBMS). Use the Internet to research open source DDBMS software. Use Dates 12 rules for distributed databases to evaluate the software. Are there any open source DDBMS software programs that follow all 12 rules? Which open source DDBMS would you recommend TAL Distributors use? Justify your recommendation and be sure to cite your references."
