Architecture of the Erlang odbc application
(对于我们编写c接口很大的借鉴意义,极大的提高了系统的稳定性，数据通信用tcp socket而不是pipe 提高通讯速度，port机制为了扑捉c程序的非正常退出, controlling进程用于提供timeout通知，数据格式直接用term, c程序直接用ei构造和解码格式 一切看起来都简单 设计的太精妙了)

（文章写的相当不错 很好的介绍了erlang的优点）
提起Erlang语言，相信许多人都会挠头，因为它实在是太陌生了。在2007年6月由TIOBE Programming Community提供的程序语言排名中，Erlang占有率仅为0.08%，排名第49位。与之形成鲜明对比的是，Java以20.025%的占有率高居榜首，紧随其后的是C（15.967%）、C++（11.118%）、VB （9.332% ...

8.7 Internal Representation of Records
Record expressions are translated to tuple expressions during compilation. A record defined as
-record(Name, {Field1,...,FieldN}).
is internally represented by the tuple
{Name,Value1,...,ValueN}
where each ValueI is the default value for FieldI.
To each mo ...

Normally, connections are established automatically when another node is referenced（也就是说给节点发信息 ping rpc等等）. This functionality can be disabled by setting the Kernel configuration parameter dist_auto_connect to false, see kernel(6). In this case, connections must be established explicitly by calling n ...
9.4 Exit Reasons
When a run-time error occurs, that is an exception of class error, the exit reason is a tuple {Reason,Stack}. Reason is a term indicating the type of error:
Exit Reasons. Reason Type of error

11.5 Hidden Nodes
In a distributed Erlang system, it is sometimes useful to connect to a node without also connecting to all other nodes. An example could be some kind of O&M functionality used to inspect the status of a system without disturbing it. For this purpose, a hidden node may be used.
...
The default when a connection is established between two nodes, is to immediately connect all other visible nodes as well. This way, there is always a fully connected network. If there are nodes with different cookies, this method might be inappropriate and the command line flag -connect_all false mu ...
