31. Dr. Armstrong spends his time pointing out how Erlang attempts to implement object ideas and OO language characteristics.

32. Fortunately, Erlang has a solution for this distributed programming problem too.

33. One of its interesting features is the actor-based concurrency support that is modeled after the Erlang programming language.

34. The book is suitable for everyone from novices in functional languages to those who have experience with Erlang and want to improve their skills.

35. Pattern matching in Erlang also handles the execution flow of individual statements, and extracts the individual vales from compound data types (tuples,(http://sentencedict.com/erlang.html) arrays).

36. A main difference between Erlang and more popular languages is that Erlang is primarily a functional programming language.

37. In an object oriented programming language these rules would most likely be modeled by a list of instances; in Erlang we use functions.

38. Within Erlang, you can surround the individual operations within a process and then use messaging to handle the updates.

39. To start using distributed programming, first you need to start Erlang and give each instance of Erlang a unique name.

40. By statistical analysis,their distribution charac- ters are deduced that the non-production waiting time follows the Erlang distribution,while the fuel price fol- lows Weibull distribution.

41. This model is based on message passing, and is somewhat similar to the actor model used in Erlang and Scala.
