Why organizations need IS; IS vs DBMS

Short answer

Organizations need information systems for decision support, operational automation, competitive advantage, handling large data volumes, coordination, planning, customer service and legal compliance. An IS is a complete system including people and procedures, while a DBMS is only the software for data storage and retrieval; an IS uses a DBMS.

Why do organizations need Information System? Differentiate between Information System and typical database management system.

Why organizations need an Information System

  1. Support decision making - managers get timely, accurate information instead of guessing.
  2. Efficient operations - routine work (billing, payroll, inventory) is automated, faster and less error-prone.
  3. Competitive advantage - better service, lower costs and new products.
  4. Handling large data volume - modern organizations produce more data than can be managed manually.
  5. Coordination and communication - departments and branches share the same information.
  6. Planning and control - monitoring performance against targets.
  7. Customer service - 24/7 services, order tracking, personalization.
  8. Legal and record-keeping needs - audit trails, tax and regulatory reports.

Information System vs DBMS

A DBMS is software that defines, stores and manages data. An IS is a complete system that uses data (usually through a DBMS) to produce information for people.

An IS depends on a DBMS, but a DBMS alone does not give business information without applications and users.
