PL/SQL collections are data structures used to store multiple elements of the same data type in Oracle databases.

• PL/SQL collections include associative arrays, nested tables, and VARRAYs.

• They can be used to store data temporarily during processing.

• Examples include storing employee names in an array or tracking customer orders in a nested table.

Normalization in database is the process of organizing data in a database to reduce redundancy and improve data integrity.

• Normalization involves breaking down a database into smaller, more manageable tables.

• It helps in reducing data redundancy by storing data in a structured manner.

• Normalization ensures data integrity by minimizing data anomalies.

• There are different normal forms such as 1NF, 2NF, 3NF, BCNF, and 4NF.

• For example, in a database of students and courses, instead o...read more

A trigger is a special kind of stored procedure that is automatically executed when certain events occur in a database.

• Triggers are used to maintain referential integrity, enforce business rules, and automate actions in response to data changes.

• They can be defined to execute before or after an INSERT, UPDATE, or DELETE operation on a table.

• For example, a trigger can be set up to automatically update a timestamp column whenever a row is modified in a table.
