Exam & Study Guide

The exam has not yet been scheduled. Please check back later.

As for relevant contents: Relevant are all materials covered in class or in the reading assignment. In particular, prepare for the following topics:

1. All questions from the tutorial.

2. Programming in Python: Python will be a substantial part of the exam. We will present complete programs or code snippets, and you will have to decide what will happen when you start the respective program. Options may include

a) various alternative screen outputs,

b) the option "Something else, but not an error" and

c) the option "An error message".

So you will need to understand exactly what the respective program is doing. We will not go beyond the language subset that was covered in class, but we expect that you really understand this subset. Guessing will not help in this part of the exam!

Learning Goals

This class will explain the use of computer technology for business purposes. Students will learn how IT and the organizational perspective on enterprises mutually influence each other, and how this can be exploited for more efficient business operations. Also, the foundations of computer hardware, software engineering, and typical business applications will be introduced. Eventually, students will learn to use computer technology effectively and efficiently for business purposes. They will understand the transformation of the business world currently in progress and be well prepared for a career in today's dynamic and global economy.
