Databases and Communication Networks 1

MKIB3204

Prof. Dr.-Ing. Holger Vogelsang

7 ECTS points / 7 Contact hours

3rd Semester

Computer Science 1, Computer Science 2

none

The students know the current models of communication and database technology and are able to classify and evaluate unknown, e.g. new systems. They are familiar with the advantages and disadvantages of different architectures and will be considered when selecting the architecture for their own products.

In the database area, they are largely familiar with the SQL-92 standard and are able to select, set up and safely operate database systems. The students are able to analyze given facts, to transfer these facts into a normalized data model, to create this data model under SQL and to use the resulting SQL databases under object-oriented languages.

In the field of communication networks, students know the individual layers of the TCP/IP layer model and understand the tasks and service models of each layer. They can characterize and compare different protocols of each layer. They can analyze the requirements of a given application, select the most suitable protocols for that application, and combine them into a functioning network stack. You can also use the client-server approach and socket programming techniques to solve your own problems.

Exercise 1 Semester (not graded)

The knowledge learned in "Databases 1" is deepened and practiced in group work. The interaction of a database with a higher programming language (Java) is understood. The use of SQL (DCL; DML; DDL), transactions and isolation levels and the avoidance of deadlocks is mastered.

A database application for warehouse management will be designed and prototypically implemented. This includes the setup of a DB schema, the design and testing of SQL queries, the use of transactions and transaction levels as well as the programming of queries and transactions with Java using JDBC based on Oracle (the preparation for the laboratory should be done in PostgreSQL or MySQL).

Finally, several given verbal facts are analyzed, transferred to an Entity Relationship model, normalized, transferred to a physical schema and finally created in SQL. Finally, the handling of the OR mapper Hibernate is practiced.
