what is records in database

Oracle Database allows audit trail records to be directed to an operating system audit trail if the operating system makes such an audit trail available to Oracle Database. Statement auditing is the selective auditing of related groups of statements regarding a particular type of database structure or schema object, but not a specifically named structure or schema object. Audit records can be stored in either a data dictionary table, called the database audit trail, or in operating system files, called an operating system audit trail. Enable future accountability for current actions taken in a particular schema, table, or row, or affecting specific content, Deter users (or others) from inappropriate actions based on that accountability. FGA provides an extensible interface for creating policies to audit SELECT and DML statements on tables and views. 2. Schema object auditing is very focused, auditing only a single specified type of statement (such as SELECT) on a specified schema object. Setting audit BY ACCESS inserts one audit record into the audit trail for each execution of an auditable operation within a cursor. A Database Management System (DBMS) is a software application that interacts with the user, applications and the database itself to capture and analyze data. The information itself can be stored in many different ways; before digital computers, card files, printed books and other methods were used. Enables you to audit specific statements on a particular schema object, such as AUDIT SELECT ON employees. Security policies can trigger auditing when specified elements in an Oracle database are accessed or altered, including the contents within a specified object. https://www.britannica.com/technology/database.

Consider the following series of SQL statements: As a result of the query on employees_departments, two audit records are generated: one for the query on the employees_departments view and one for the query on the base table employees (indirectly through the employees_departments view). In some cases, an operating system log allows such an action to complete. If you use the BY SESSION clause instead, then your audit trail will contain a single audit record for each session, for each user and schema object. Most operating systems provide administrators with sufficient information and warning to enable them to ensure this does not occur. Browse through all records. Applications call the syslog() function to log information to the syslog daemon, which then determines where to log the information.

If someone moves to another municipality, their personal data moves with them. For example, if the statement clause TABLE and the system privilege CREATE TABLE are both audited, then only a single audit record is generated each time a table is created.
