Data Workflow

[basicthinker]

Topic branch from #2: Lack of data flow

• Does it make sense to support a text-based, versioned Git-like database? Maybe just Git, like how Wiki can be based on Git.
• Furthermore, we can specify a workflow such as PR to update and collaborate on the table data.
• The number of comments always shows along with a record. But it is better to be able to resolve comments and reserve them as comments along with a PR.
