Continued Erlang (4 days)

This course continues where Basic Erlang leaves off. It covers the more advanced features of Erlang such as distributed programming and communication with the environment. It also gives an introduction to some tools and libraries and discusses how to write robust, efficient Erlang programs.

Objectives

After the course, the participants should
  • be able to write Erlang programs handling large amounts of data
  • be able to write Erlang programs communicating with the outside world
  • be able to write distributed Erlang programs
  • have knowledge of important aspects when writing robust, efficient Erlang programs
  • have knowledge of the tools and libraries provided

Who should attend

The course aims at Erlang programmers who have participated in the Basic Erlang course and now wants to gain more knowledge about the language and the programming environment.

The course also introduces concepts which are essential for programming using OTP, and is thus a prerequisite for the OTP Application Developer's course.

Prerequisites

Basic Erlang course or the corresponding knowledge.
At least a few weeks experience of Erlang programming.
Try out the diagnostic test.
