Synopsis:

The goal of this course is to introduce basic concepts and principles of operating systems

(OS), like processes and threads, their scheduling, mutual communication and

synchronization, time-dependent errors and deadlocks. Attention is also paid to memory

management, virtual memory, management of secondary storages, file-systems and data

security. The second part of the course is focused at databases, their types and

structures, concurrent data access and transactions.

Requirements:

Basic knowledge of C programming

Syllabus of lectures:

1.Basic concepts: operating system (OS) and its kernel, hardware dependency, processes, threads, scheduling. OS types.

2.Compiling and linking, libraries, OS services and calls, dynamic libraries and run-time linking

3.Implementation and life-cycle of processes and threads. Scheduling algorithms. Real-time OSes and scheduling in them.

4.Communication among processes and threads, critical sections, time-dependent errors, synchonization tools. Classical synchronization problems and their solution.

5.Deadlocks: definition, conditions, solution possibilities

6.Memory management: Basic techniques. Virtual memory, swapping, paging, segmentation, page-replacement algorithms.

7.File-systems, organizing data on the secondary storage, principles, standard solutions, data security.

8.Distributed computing, client-server architectures. OS components supporting computer networks and their programming.

9.The database concepts and types. Data modelling, E-R model, decomposition and normalization. Data integrity

10.Relation, relational model, keys (proper and foreign), data model quality. Object-oriented and object-relatinal databases.

11.Database query languages. Relational algebra and calculus. SQL language queries, DDL, DML). XML data representation.

12.Concurrent access to data, transactions, atomicity, error recovery, concurrency coordination.

13.Physical data organization, indexes, B-trees, bitmap indexes, link-up to OS.

14.Wrap-up, spare time.
