Database System

Database systems are the combination of a database and database management system (DBMS). The purpose of database systems is to abstract data views to users such that technical details about the access and manipulation of that data are hidden.

Databases are electronic stores of related data. These may include things like property data, stock market prices during a period of time, or your grocery list. Technically, databases don’t have to be digital—a repository of related data contained on paper would qualify. An example would be property records at one’s local Courthouse.

Database management Systems (DBMS) are the logical systems that facilitate access to the data in databases. These systems can be used to add new data, manipulate existing data, or even remove data from databases. Examples of a DBMS include PostgreSQL, Oracle Database, or Microsoft Access. These systems each provide functions to interact with data in technically abstracted ways.
