Module 7: Linux System Programming, Data Management, MySQL

Abstract:

Linux System programming is all about programming computer system software ising C on Linux. The primary distinguishing characteristic of systems programming when compared to application programming is that application programming aims to produce software which provides services to the user directly, whereas systems programming aims to produce software and software platforms which provide services to application software, are performance constrained, or both. it also covers data management using terminals and interfaces using curses. Database query is also used extinsively using MySQL.
