An application developer needs to ensure their software can efficiently add new records, modify existing entries, and query for specific information within a company's relational database. Which of the following is the standard method for an application to perform these operations?
Exporting the database to a flat file for manipulation
Programmatic access using SQL
Restoring the database from a modified backup file
The correct answer is programmatic access using SQL. This method involves using a programming language to send Structured Query Language (SQL) commands like INSERT, UPDATE, SELECT, and DELETE to the database. It is the standard, most efficient, and scalable way for applications to interact with relational databases. Direct manual entry is for human users and is not suitable for automated application tasks. Exporting to a flat file is inefficient for real-time transactions and introduces data synchronization issues, which is a key reason to use a database over a flat file system. Restoring from a backup is a maintenance or recovery task, not a method for routine data manipulation by an application.
