軟體簡介:
　
A bad data model leads to an application that does not perform well.
Therefore, when developing an application, you should create a good data
model from the start. However, even the best logical model can’t help when
the physical implementation is bad. It is also important to know how SQL
Server stores and accesses data, and how to optimize the data access. Database
optimization starts by splitting transactional and analytical applications.
In this course, you learn how to support analytical applications with logical
design, get understanding of the problems with data access for queries that
deal with large amounts of data, and learn about SQL Server optimizations that
help solving these problems.
