Prerequisites

Before attending this course, students must: Have working knowledge of data storage. Specifically, knowledge about row layout, fixed length field placement and varying length field placement. Be familiar with index structures and index utilization. Specifically, they must understand the interaction between non-clustered indexes, clustered indexes and heaps. They must know why a covering index can improve performance. Have had hands-on database developer experience. Specifically, three years of experience as a full-time database developer in an enterprise environment. Be familiar with the locking model. Specifically, students should have an understanding of lock modes, lock objects and isolation levels and be familiar with process blocking. Understand Transact-SQL syntax and programming logic. Specifically, students should be completely fluent in advanced queries, aggregate queries, subqueries, user-defined functions, cursors, control of flow statements, CASE expressions,
