Databases that carry their data in the form of tables and that represent relationships using foreign keys are called relational databases. Foreign keys are columns that are keys of a different table than the one in which they reside. The relational model was the single, standard way of processing databases for over thirty years. Recently, however, new styles of database processing have started appearing. Part of the reason is that the major principles of the relational model–fixed-sized tables, representing relationships with foreign keys, and the theory of normalization came about because of limited storage space and limited processing speeds back in the 1960s and early 1970s. At some point, maybe the mid-1990s, these limitations were removed by improved storage and processing technology and today they do not exist. In other words, the relational model is not needed today. Other reasons for the development of nonrelational databases include the need to gain faster performance using many servers and to store new types of data such as images, audio, and videos.
