Introduction to Databases. By Dixon Kimani History of Databases. It is important to first realize that the organized, systematic methodology of storing records we know and heavily depend on in databases is not a recent invention. What is recent is the computerization of this methodology beginning in the 1960s. Note that even paper-based records, including ledger-based bookkeeping, are.
Lesson: Introduction to Databases. A database constraint is used to ensure that data in a relation matches the modeller’s view of how that data should be stored. For example a constraint on your postal code could ensure that the number falls between 1000 and 9999. A Primary key is one or more field values that make a record unique. Usually the primary key is called id and is a sequence. A.
