How do you diagnose slow-running database queries?

By running EXPLAIN plans on database queries, checking index coverage, and monitoring query lock wait times.

What is your indexing strategy?

We create indexes on fields used in filters and join operations, while avoiding redundant indexes that slow down write tasks.

By binding the database to localhost or private subnets, using password authentication, and restricting port access via firewalls.

By utilizing parameterized queries and object-relational mapping (ORM) systems that separate query syntax from user inputs.

We utilize normalization rules for SQL structures, and balance normalization with embedded document models in NoSQL systems.

By executing snapshot runs on secondary replica members, preventing read/write locks on the main primary database node.
