Buck Woody Senior Microsoft SQL Server Specialist SESSION CODE: DAT210

Database design has the greatest impact on performance, reliability and security. Yet many IT professionals focus only on the physical model of the database. This session takes a simple set of requirements and decomposes the design process, using basic methodologies such as Entity Relationship Diagrams (ERD), Object-Role Modeling (ORM) and Unified Modeling Language (UML) to create an effective design. It covers the basic tools you can use for each of these approaches for SQL Server. Objective #1 Learn the process for decomposing requirements to a logical design that can be communicated to Business and Development teams. Objective #2 Understand the principals of Normalization and a simple process to Normalize. Objective #3 Understand various tools available to design and implement a database.
