Common design patterns in Angular include Singleton, Observer, Factory, and Dependency Injection.

• Singleton pattern ensures a class has only one instance and provides a global point of access to it.

• Observer pattern defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically.

• Factory pattern is used to create objects without specifying the exact class of object that will be created.

• Dependency I...read more

SQL queries to remove duplicates typically use DELETE with a subquery or the DISTINCT keyword in SELECT statements.

• Use DELETE with a subquery to remove duplicates: DELETE FROM table_name WHERE id NOT IN (SELECT MIN(id) FROM table_name GROUP BY column_name);
