UNIQUE constraints: These prevent duplicate entries in a column or set of columns. NOT NULL constraints: These ensure that a column cannot have a NULL value.
Here’s an example of a simple CHECK constraint:
CREATE TABLE employees ( employee_id INT PRIMARY KEY, first_name VARCHAR(50), last_name VARCHAR(50), salary NUMBER(8,2) CHECK (salary > 0) );
3. Data Audit Trails
Maintaining an audit trail is crucial for tracking changes and ensuring data accuracy over time. Oracle’s audit features can log changes made to data, who made them, and when. This is invaluable for both compliance and troubleshooting purposes.
