Design: DB design

[OrAbramovich]

Database design is the process of producing a detailed data model of database. This data model contains all the needed logical and physical design choices and physical storage parameters needed to generate a design in a data definition language, which can then be used to create a database. A fully attributed data model contains detailed attributes for each entity (https://en.wikipedia.org/wiki/Database_design).
