2. Data Auditing
Data auditing involves tracking and recording changes to the data. This method is essential for maintaining data accuracy and ensuring compliance with regulatory requirements. Oracle provides built-in auditing capabilities:
Oracle Audit Trail: This feature captures all DDL, DML, and other database activities. It helps track changes, identify who made the changes, and when they occurred. Fine-Grained Auditing: Allows you to control auditing at a very granular level, focusing on specific tables, columns, or types of operations.
3. Validation Rules
Setting up validation rules ensures that data entered into the database adheres to predefined criteria. This method helps maintain data accuracy by preventing incorrect or invalid data from being stored.
Check Constraints: Oracle allows you to define check constraints that enforce rules at the database level.
CREATE TABLE employees ( employee_id INT PRIMARY KEY, name VARCHAR2(100), salary NUMBER CHECK (salary > 0) );
Triggers: Triggers can enforce complex validation rules and can be used to update or validate data before it is inserted or updated in the database.
4. Data Reconciliation
Data reconciliation involves comparing data across different sources to ensure consistency. This method is particularly useful when integrating data from multiple systems.
Cross-System Comparisons: Use SQL joins and other comparison techniques to reconcile data from different sources. sql SELECT a.employee_id, a.salary, b.salary FROM source_a a JOIN source_b b ON a.employee_id = b.employee_id WHERE a.salary!= b.salary;
Leveraging Advanced Tools and Techniques
For more sophisticated data accuracy measurement, consider the following advanced tools and techniques:
1. Oracle GoldenGate
Oracle GoldenGate is a powerful tool for data integration, replication, and real-time data synchronization. It ensures data consistency across multiple databases and systems.
