Modern Relational Databases

Question

What is the modern relational database?

Kunal Naik · Answer

Hi RDBMS is a DBMS in which data is stored in tables and the relationships among the data are also stored in tables. The data can be accessed or reassembled in many different ways without having to change the table forms. To know more refer following link Click Here

Thanks Kunal.

Sam Hobbs · Answer

The article that Kunal suggests is a good simple description. At the most fundamental level a relational database stores data as rows and columns and the number of columns in a table is the same for every row. They are called relational because there is a mechanism for specifying relations among the data. The result is something that is simple and powerful compared to most database systems that existed before the relational design.

Relational Database Management Systems (RDBMS) ship with an auditing tool that allows database administrators to monitor the database from a security perspective. Information provided includes what events occur (logon/logoff) what database objects are being accessed what data is queried etc. The most common reason for using auditing is to determine when a database user executes some sort of SQL. The SQL statement is logged by the auditing subsystem in the form of a clear text log file xml file binary file audit table(s) or remote system log. Auditing occurs separately from any transaction – even when a transaction is rolled back the auditing log will contain records about statements executed if the auditing is configured to do so. It is extremely important to properly configure auditing by only auditing the events that require monitoring. Auditing has an impact on performance so you shouldn't audit what isn't necessary. In addition the audit trail (audit data) location should be protected to avoid manipulation by any user. This necessary step ensures accuracy of the logs. Most modern databases have similar auditing architecture. Auditing should be installed enabled and configured to allow the audit data to be examined via SQL query. Let's examine how this is done in three of the most popular databases – Microsoft SQL Server 2008 R2 Oracle Database 11g R2 and Sybase ASE 15.5. https://www.infosecisland.com/blogview/15529-Native-Auditing-In-Modern-Relational-Database-Management.html
