What can applications use to interact with a database?

Show Suggested Answer Hide Answer
Suggested Answer: D

SQL is the standard language for communicating with relational databases. Applications use SQL to:

* Retrieve data: SELECT queries are used to fetch specific data from database tables.

* Modify data: INSERT, UPDATE, and DELETE statements allow applications to add, change, or remove data in the database.

* Manage database structure: CREATE, ALTER, and DROP statements let applications create tables, modify their structure, or delete them entirely.

D) SQL has to be the answer, right? SQL is the language used to interact with and manage databases. The other options don't seem relevant to me.

I'm a bit confused by this question. I know we talked about different ways to interact with databases, but I can't recall if IIAS or the operating system were options. I'll have to review my notes before answering.

Okay, let me walk through this step-by-step. Applications need a way to communicate with the database, and Java Database Connectivity (JDBC) is the standard API for that. So I'm pretty confident A is the right answer here.
