SQL databases have supported the LIKE operator for a very long time and it will allow you to compare a string to a pattern and has wildcard characters to match any single character or zero or more characters. HCL Informix also supports the MATCHES operator that give you some more wildcard matching options. Similar to the LIKE predicate, MATCHES has support for wildcard characters to match any single character or zero or more characters. It also has the ability to match single character from a set or range of characters or match a single character that is not in a set or range of characters. These are both examples of simple regular expressions.

Databases are historically a great place to store data and retrieve data. However, they are not always the easiest to process events and receive alerts from, especially in real time or near real time. You can use a specialized software for this, but what if you wanted the best of both worlds? An enterprise level database for storage and security, but with the ability to process events and alerts as they happen. Updated: 8/30/18
