Which commands are typically used to interact with a relational database programmatically?

The choice that correctly identifies the commands typically used to interact with a relational database is SQL commands. SQL, which stands for Structured Query Language, is the standard language used for querying and managing data in relational databases. It allows users to perform a variety of operations, including inserting, updating, deleting, and retrieving data from the database.

When working with databases, SQL commands are essential because they provide the syntax and structure needed to communicate with the database management system (DBMS). For instance, commands like SELECT, INSERT, UPDATE, and DELETE are all part of SQL and are specifically designed to manipulate and manage data effectively.

In contrast, HTML commands are primarily used for structuring content on the web and do not interact directly with databases. JavaScript commands facilitate client-side scripting and can be used to make requests to a database via APIs or web services, but they are not a database interaction language on their own. Similarly, Python commands can be utilized for database interactions through libraries such as SQLAlchemy or SQLite, but Python itself is a programming language rather than a dedicated database language like SQL. Thus, for direct interaction with relational databases, SQL commands are the appropriate choice.
