Database internals and algorithms
Databases are essential part of any business - and knowing how to create and manage them can be a great advantage. Through this course you will learn algorithms and design principles used in commercial RDBMS. By understanding RDBMS algorithms, engineers can design, optimize and tune databases better. For instance, they will know when adding index will benefit transaction response time or make the performance worse, how to optimize indexes, how to identify and solve bottlenecks and more. The course covers disk and memory IO management, database storage structures and indexes, concurrency control protocols, transactions and SQL optimizer. This course is designed for developers and DB administrators who are familiar with SQL databases. It is not bind to a specific database vendor. Oracle, SQL Server, Sybase, DB2, MySQL, Postgress or other users will benefit from this course.
