A database is an organized collection of structured information, or data, typically stored electronically in a computer system. A database is usually controlled by a database management system (DBMS). Together, the data and the DBMS, along with the applications that are associated with them, are referred to as a database system, often shortened to just database.
Data within the most common types of databases in operation today is typically modeled in rows and columns in a series of tables to make processing and data querying efficient. The data can then be easily accessed, managed, modified, updated, controlled, and organized. Most databases use structured query language (SQL) for writing and querying data.
Database is defined as a collection of data organized in a structural way and optimized for speedy search and retrieval. It can also be defined as an organized collection of data used for the purpose of modeling some type of organization or organizational process (Hernandez,2013). Databases are enable companies and individuals to make in decisions and analyses that provide benefits, security and improvements in their daily transactions. There are various types of databases depending on the requirements applicable to the various types of organizations, business or individual that use databases. Earlier forms of database include hierarchical and network databases. Some of the recent databases are relational database models. Hierarchical databases are database models usually structured with a root and tree branches design. They also have parent/child characteristics which include the fact that data in one table of database corresponds to same data in another table that are related by the same data values. One advantageto using a hierarchical database is that a user can retrieve data very quickly because there are explicit links between the table structures.
