Q.Define ERP. State any two core features of an ERP system.

ERP is defined by what it integrates and how; naming a couple of its core features shows understanding.

Definition: Enterprise Resource Planning (ERP) is a single, integrated software system that plans and manages all the resources of an entire organisation — money, materials, machines, people, and information — by bringing all its departments onto one platform that shares a common, centralised database.

Core features (any two required):

1. Integration — all functions are connected, so an action in one area automatically updates the others. This is the most important feature.
2. A single centralised database — all data is stored once, in one place, and shared by every module ('one version of the truth').
3. Real-time processing — information is updated the instant a transaction occurs.
4. Modular structure — the system is built from separate but connected modules.
5. Automation and standardisation of business processes.

A definition that says only 'ERP is business software' is too vague — mention integration and one central database, which are what make it ERP. When two features are asked, give two distinct ones, not the same idea twice.
