Join Simon Allardice for an in-depth discussion in this video What about database efficiency?, part of Foundations of Programming: Code Efficiency.
I wanted to touch upon one more thing before I wrap this section up.…As you may have noticed I've avoided having…a dedicated section on database efficiency in this course.…And mainly because this is such a deep and specialized area.…Working on database efficiency is often a job in itself.…And this may be something we have an entire…course on in the future, but for right now…the first tier of database efficiency is really the…same things I've talked about over the last few hours.…A lot of database…efficiency work begins with the core normalization questions, some of…which are covered in our Fundamentals of Programming Databases course.…
We begin by designing for clarity.…We'd normalize the database, and later we may de-normalize for performance.…But it then tends to dive into indexing and query…analysis tools, that are usually specific to the database platform.…But it's the same perspective, we're learning the tools for measurement.…We assume we don't know where…the problem is until we measure it. And a database is a disk resource.…
Learn to choose the right data types, understand the pitfalls of using high-level languages, and decide where to spend your time. Plus, see how the underlying memory management model may have more of an impact than you realize, and what performance issues you can expect working with databases and web services.
