Database management systems (DBMS) are crucial business foundations. In addition to effectively creating and maintaining databases, these systems perform the following functions:

• Control redundancy
• Restrict unauthorized access
• Provide persistent storage for program objects and data structures
• Permit inference and actions using rules
• Provide multiple user interfaces
• Represent complex relationships among data
• Enforce integrity constraints
• Provide backup and recovery

The most widely utilized DBMSes today are relational database management systems (RDBMS). These table-based systems enable engineers to avoid writing lengthy computer programs to express database queries and enforce database integrity constraints without affecting the database's completeness. Other benefits of leveraging a RDBMS include:

• Unbeatable performance
• Enormous benefits to users in capability and power
• Truly scalable and distributable systems
• Able to easily take advantage of new hardware technology
• Flexibility for evolution of users' data
• Provides a solution for all types of data needs
