database is a relational database. Relational databases are made up of data which is stored in tables, and unlike object orientated databases there is a greater level of structure. The
tables will each have names and the rows of data will all be the same object types with columns describing the data type. The database can be accessed with the
use of standard query language (SQL), and tables may be combined or cross referenced with each other through the use of relational algebra. There are certain types of advantage associated
