A schema is simply a visual way of representing the data you wish to search, share or collect. It’s typically shown as a table (a group) of records (members of the group) with fields (properties of the members). A table may have related data with another table, such as an index number, and this relationship is shown by a connector to the specified field. Organizing the data for thorough and efficient input, browsing and retrieval is the purpose of a database schema.
You can use the diagramming tools in FigJam or LucidChart for free to design your database schema. The diagram should be rendered as a pdf or png file to be included on the team website.
