Information Systems 101

Last week’s lecture focused on the rise of IT’s role in businesses today. With the advent of the Internet, mobile devices, social networks, etc. it became very apparent that for a business to succeed, it needs to keep ¬†current with technology. The resulting business model had to make sure that IT investment is front and center to create new revenue streams, maintain scalability and remain¬†competitive.

One of the building blocks of an IT infrastructure are the different Information Systems that comprises it. Information systems basically are the hardware and software systems that have specific functions to process different kinds of data. We discussed several major types:

  • Transaction Processing Systems (TPS)
  • Customer Relationship Management (CRM)
  • Supply Chain Management (SCM)
  • Enterprise Resource Planning (ERP)
  • Business Process Management (BPM)
  • Business Intelligence (BI)

Just to give a quick example from experience, in Georgia Tech we have a few of these systems running. Being in higher education, we have different requirements from corporations. For example, we run Sungard Banner which is a very industry specific system designed to manage student data and campus services.

For our HR and financial data, we run Oracle’s Peoplesoft and for business intelligence, we have several between Oracle’s Hyperion, SAP’s Business Objects and IBM’s Cognos.

So that’s basically what information systems are in a nutshell. Look for the IS model I will be making for my past business models.
