How to create fast and much more efficient database

This document discusses creating a database using Entity Framework code first approach with a WCF service. It involves three parts: creating the database using EF code first, defining a context for the database, and writing WCF services. Classes with data contract and data member attributes will map to database tables and columns. A context class is defined to access and interact with the database. Interfaces are written to define the functionality exposed by the WCF service. Code is then written to implement the interfaces and define the service logic. Finally, a class is written to access the service and handle client calls.
