Which one of the following is not a database management software ?

Database Management Systems (DBMS) are software applications designed to store, retrieve, and manage structured data. Oracle, MySQL, and MS-Access are all well-known examples of relational database management systems (RDBMS):

• Oracle is a powerful enterprise-level database system.
• MySQL is a widely-used open-source database system, often used for web applications.
• MS-Access is a desktop-based database application provided by Microsoft as part of the Office suite.

In contrast, MS-Word is a word processing software. Its primary function is the creation, editing, and formatting of text-based documents (such as reports, letters, and resumes). It does not possess the structural capabilities, indexing, or query language support (like SQL) necessary to function as a database management system.
