SQL, Structured Query Language, is used to search databases (data structures) for specific records for specific data. Those that develop and use MySQL databases, or access apps based on MySQL databases, most become familiar with the SQL features.
The SQLMatrix: Concepts poster covers the basics needed to understand how SQL statements are used to develop and work with SQL based databases. The SQLMatrix Poster can be found at our SQLMatrix Redbubble Store along with over 100 other products based on the SQLMatrix design.
