Database Management Systems (DBMS)
The Entity Ideas in Database Management Systems
The entity ideas are developed from Database Management Systems (DBMS) which refers to system software or computer packages that assist in collecting, controlling, organizing and using the same facts required by application programs. DBMS gives the platform and capability to build and retain a well-organized database system. Therefore, an entity regarding administration information system refers to a person, thing, place or match in which we store as well as maintain facts and information for current or future use. The entity must have wonderful features that describe it and separates it from other peripheral objects so as to function distinctively to fulfill the objectives. An entity ought to have sub-set that operates independently to execute certain activities through its database but feeds the processed final data to the parent entity to avoid any form of data redundancy in the system (Laudon & Laudon, 2014). The functions of the sub-entities must be in line with the first objectives to mitigate any sub-optimality that is likely to arise within the information system.

All the information and data must be recorded and analyzed before making the final representing on the findings hence all these scenarios are entities (Laudon & Laudon, 2014). Additionally, persons or individuals in cannot operate in vacuum hence the need for structures where installation of information systems takes place. The university lecture halls, computer laboratories and even libraries where research information and data are retrievable are all places.
