A Schema is a JSON object that allows you to define the shape and content of documents and embedded documents in a collection. You can use a schema to require a specific set of fields, configure the content of a field, or to validate changes to a document based on its beginning and ending states.

This issue is for discussing various approaches to implement Schema for AvionDB. The goal here is to pool different views on:

• Why do we need Schema?
• How we can implement Schema for AvionDB? (at least a rough idea)

This issue would be resolved to create a new issue with technical specifications for implementing Schema model.

This is an open discussion, feel free to add your comments, suggestions.
