Terminology: What is the correct name for a structured collection of related facts and data that can be accessed, managed, and updated efficiently by applications?

Introduction / Context:
Clear terminology is essential in data management. When organizations collect related data to support transactions, analytics, and reporting, they rely on a system that organizes, stores, and controls access systematically. This structure underpins nearly all business applications and services.

Given Data / Assumptions:

• The data items are related and accessed by applications.
• We require efficient storage, retrieval, and update.
• Standard IT vocabulary is intended, not niche jargon.

Concept / Approach:
A database is an organized collection of related data managed by a Database Management System (DBMS). It supports concurrency, durability, security, indexing, and query capabilities. Alternative phrases like “directory information” or “information tree” describe specialized structures or metaphors, not the general-purpose managed collection used by applications across domains.

Step-by-Step Solution:

Verification / Alternative check:
Any DBMS tutorial or textbook defines a database precisely as an organized collection of data for efficient manipulation and querying.

Why Other Options Are Wrong:

• Directory information: often refers to identity/address listings or LDAP entries.
• Information tree: a structural metaphor, not a standard system name.
• Information provider: an entity, not a data store.

Common Pitfalls:
Confusing storage structures (trees, files) with the comprehensive system (database + DBMS) that manages them.

Final Answer:
Database
