What is relational database management?
One of the most popular database management system, available in the market is called relational database management system, because they are very easy and simple to operate. These systems are normalized by using data which are generally stored in tables. The data in the system can be associated with the data that is present in any of the tables, be it the same or different. While relational models are sometimes less efficient than other systems, this is not a major problem as most modern computers have high processing power and memory, that can easily help brands to overlook this small disadvantage. In this model, data is stored in predefined structures and they are usually manipulated through the use of SQL or Structured Query Language. Some other systems that uses relational database management includes Oracle, IBM, Ms SQLServer, mySQL, PostgreSQL among many others.

What Is Database Security
Why Is It Important
- By definition, a data breach is a failure to maintain the confidentiality of data in a database. How much harm a data breach inflicts on your enterprise depends on a number of consequences or factors: 1. Compromised intellectual property:Your intellectual property—trade secrets, inventions, proprietary practices—may be critical to your ability to maintain a competitive advantage in your …
Common Threats and Challenges
- Many software misconfigurations, vulnerabilities, or patterns of carelessness or misuse can result in breaches. The following are among the most common types or causes of database security attacks and their causes.
Best Practices
- Because databases are nearly always network-accessible, any security threat to any component within or portion of the network infrastructure is also a threat to the database, and any attack impacting a user’s device or workstation can threaten the database. Thus, database security must extend far beyond the confines of the database alone. When evaluating database security in you…
