Full-text search is handled with a different kind of index, typically something like an inverted list of words and their record and offset locations. Standard relational database indexes tend to use short fields or even hashes, for performance reasons. Still others expand the databases beyond their own tables, beyond a single server, and beyond SQL queries. Others involve speeding up access to frequently used tables. Some involve supporting different kinds of data, along with the indexes and search functions to use them. In this article we’ll discuss many of the ways that traditional SQL databases are improving. Oracle Database, Microsoft SQL Server, MySQL/MariaDB, and PostgreSQL may trace their origins back to the 1980s, but they are all still under active development, and not just to fix bugs and tweak performance. ![]() In all the excitement about NoSQL databases, distributed databases, data warehouses, and GPU-accelerated databases these days, it’s easy to forget that traditional relational databases still store and serve the mission-critical information for many, if not most, line-of-business applications. ![]()
