Lecture 02
This lecture deals with software and computer language theory starting with assembler and the abstraction level given for programming by operating systems. A theoretical part offers some insights into language theory and the Chomsky hirarchy, while the programming paradigms allow a general classification of programming languages which in general have similar structures. The lecture is closed by the comparision of compiler and interpreter.Downloads

Lecture 03
This lecture compares programming languages and offers a basic view on software development processes. A short review explains the general difference between structured and object oriented programming paradigms. The languages C, C++ and Python are used to compare the different styles and to show analogies. The developement of software follows specific aims and defines a general method which then is realized within software development processes.Downloads

Lecture 04
This lecture gives the basics for software design including modelling techniques like the Unified Modelling Language, simulation and Aspect Oriented Programming. Design and programming rules complete the setup on basic guidelines and a summary shows the advantages of Model Driven Architecture.Downloads

Lecture 05
This lecture shows a few problems given in the binary world of a computer and some numerical effects. A short review repeats the basics of the binary numeral system. In addition a standard for floating point representation is explained in combination with some numerical effects on it. A short look shows basic runtime cathegories and an overview about character codes closes this lecture.Downloads

Lecture 06
This lecture describes how to organize data effectiently. It starts with basic organizations in file systems, describes single level structures and optimized access methods like binary search and offers the basis for database organizations. These techniques like Index Sequential Access or Hashing offers possibilities to administrate data for adding, changing, searching and deleting. A short discussion about primary and secondary keys are the bridge to the lesson about database systems.Downloads

Lecture 07
This lecture deals with the wide range of databases. After a definition of what a database is, several database models are described e.g. hierarchical, network, relational and object oriented models. After a deeper look into the relational model and its design, an overview about the Structured Query Language (SQL) shows the general principles of database interface languages.Downloads

Lecture 08 / Lecture 09
This is a practical training lecture. Some of the theoretical parts can be realized with Matlab. The training deals with real altimeter data which are saved as binary files. The files should be read, ASCII-files should be saved and the tracks can be plotted over a world map.Downloads

Lecture 10 / Lecture 11 / Lecture 12 (Dr. Gruber)
This lecture introduces Software Enegineering Standards for space projects as they are applied by space agencies and space industry. Apart from the theoretical basis, examples for the different steps in a Software Engineering process from real projects are shown, which are currently running with the European Space Agency. The lecture also is the preparation for the project to be conducted in Information Technology II.
