CODASYL, the Conference/Committee on Data Systems Languages, was a consortium formed in 1959 to guide the development of a standard programming language that could be used on many computers. This effort led to the development of the programming language COBOL, the CODASYL Data Model, and other technical standards.

数据系统语言会议（codasyl）的委员会标准化了网状数据库模型，因此网状数据库模型也被称为 codasyl 模型。 网状数据库进一步发展了层次数据库模型，解决了层次数据库有且仅有一个父节点的问题。

Since the publication, in April, 1971, of the Data Base Task Group(DBTG) report(ref.1) to the CODASYL Programming Language (=COBOL) Committee(PLC) several committees and task groups of the CODASYL organization have enhanced and improved the languages ...

The Codasyl model is a proposed specification for a Data Base System resulting from international collaboration among all interested parties, including users and manufacturers. The specification is designed to fulfil user needs, and as such it incorporates many of the user facilities discussed in the previous two chapters.

2020年3月7日 · 一个命名弧线在codasyl中称为一个结合类型，即使他在技术上并没有描述任何集合。 但它指出了对于每一个箭头末端的实体拥有0个或者多个子记录类型（箭头的头部）。

CODASYL data model is a standardized data model developed by the Conference on Data Systems Languages (CODASYL), used to represent and manipulate data in hierarchical or network database structures. It defines a set of commands and data structures for accessing and managing data, and is commonly used in applications that require complex data ...

2016年8月30日 · 网状模型的典型代表是dbtg系统，也叫codasyl系统特点用网络结构表示实体类型及其实体之间联系的模型。 顾名思义，一个事物和另外的几个都有联系……这样构成一张网状图。
