Understand Oracle Grant security

Oracle offers many ways to control data access rules, including:


Let's start with the basics by looking at grant security to examine its benefits and pitfalls. The original relational model provides a method for granting privileges to users to allow for access control. This grant model was originally described by E.F. Codd and Chris Date in the original relational model and the model is standard across most commercial relational databases.

Oracle grant security takes several forms: object grants, system privilege grants, and role-based grants. The idea is that every user in the database is granted access to specific data objects to control data access.
