What can you do when database performance doesn't meet
expectations? Before you turn to expensive hardware upgrades to
solve the problem, reach for this book. "Refactoring SQL
Applications" provides a set of tested options for making code
modifications to dramatically improve the way your database
applications function. Backed by real-world examples, you'll find
quick fixes for simple problems, in-depth answers for more complex
situations, and complete solutions for applications with extensive
problems.In this work, learn to: determine if and where you can
expect performance gains; apply quick fixes, such as limiting calls
to the database in stored functions and procedures; refactor tasks,
such as replacing application code by a stored procedure, or
replacing iterative, procedural statements with sweeping SQL
statements; refactor flow by increasing parallelism and switching
business-inducted processing from synchronous to asynchronous;
refactor design using schema extensions, regular views,
materialized views, partitioning, and more; and, compare before and
after versions of a program to ensure you get the same results once
you make modifications. "Refactoring SQL Applications" teaches you
to recognize and assess code that needs refactoring, and to
understand the crucial link between refactoring and performance. If
and when your application bogs down, this book will help you get it
back up to speed.
