Description
This course will allow you to improve the performance of your programs and maintain them efficiently by teaching you the main primitives of the kernel, the creation of graphical interfaces and input masks. You will also be introduced to the modern approach to Object programming, allowing you to better master this essential tool for creating high-performance software.
Who is this training for ?
For whom ?
Computer scientists concerned with operating procedures in Unix, Linux or Windows environments.
Prerequisites
Good knowledge of the Perl language or knowledge equivalent to that provided by the "Perl Language" course ref. PRL.
