A very important issue in today’s computer and information systems is database security. In recent times considerable resources has been put into researching and addressing security needs of organizations because of the repeated reports of the impact of theft of organizational resources, unauthorised disclosure of corporate resources, and other corrupt practices which has disrupted organisational operations thereby causing serious  financial, legal, personal privacy, and public confidence problems. Several different approaches have been developed in an attempt to provide security to the database resources; amongst these are Auditing, Authentication, Encryption, and Access control. In this work, Access Control as a means of providing database security is considered, and three popular access control schemes namely Mandatory Access Control, Discretionary Access Control, And Role-Based Access Control were comparatively studied.
