Overview of IT in Enterprise context

I. Operational systems.

The most typical operational software systems are ERP enterprise resource planning (it usually includes accounting, store-keeping, POS point-of-sale...) and CRM customer relationship management systems. This software is used on daily-basis by many of the employees (business users), runs the business activities and moves the business forward. If this software does not run properly, then core activities could be not available to the clients. I.e. if in a retail-store cash-desks (POS) cannot operate.

Note: "Operational" vs. "Operating" "home>academy>Glossary>Operating Systems".

II. Decision-support systems.

One of the main deliveries in the IM information management field is the DW data warehouse and the ETL extract transform load system, which populates the DW on daily-basis or near-real-time.

The common scenario is:
  • 1. Build a live (enriched/updated on regular basis) DW. Each DW is considered as "live", i.e. updated daily or NRT near-real-time (each 30min).
  • 2. Build live Data-marts sourcing data from the DW.
  • 3. Use a BI business intelligence tool to explore the data in the Data-marts.
These three can be called the Decision-support system of the Enterprise.

You can find more by DW gurus (Inmon and Kimball) on https://de.wikipedia.org/wiki/Data-Warehouse, for example.

Demand of IM services

Traditionally, the financial services (banks and insurance companies), telcos (telecommunications) and gaming-and-gambling industries have more maturity towards the IM field. I.e. they are more likely to invest.
