"Implementations of CODASYL data base management proposals": proceedings of a two-day symposium, October The data base management system (DBMS) specifications, as published in the Report of the CODASYL Data Base Task Group (DBTG) [S1], are a landmark in the development of data base technology.

These specifications have been the subject of much debate, both pro and con, and have served. The Data Base Administrator (Remote DBA) functions included: data structure or schema, data integrity, security, and authorization.

Also a Data Base Manager (DBM) function was defined which included: operation, backup/recovery, performance, statistics, auditing. The CODASYL model used two data storage methods, BDAM and linked-list data structure.

Essentially a data base is a mass storage of data. Its concept is not a sudden breakthrough in computer technology, rather it is brought about gradually through experience and requirements. Many organisations contributed to the development of data bases; the list is long and includes computer manufacturers, software houses, user organisations.

What Goes Around Comes Around Michael Stonebraker Joseph M. Hellerstein Abstract This paper provides a summary of 35 years of data model proposals, grouped into 9 different eras. We discuss the proposals of each era, and show that there are only a few basic data modeling ideas, and most have been around a long time.

This paper presents in tutorial fashion the concepts, notation, aud data-base languages that were defined by the CODASYL Data Description Language and Programming Language Committees.

The third approach is the network approach associated with the proposals by the Data Base Task Group of CODASYL. Here data items are linked into a network in which any given link between two items exists because it satisfies some condition on the attributes of those items, for example, they share an attribute.

The database contains user data, metadata, indexes and other overhead data, and application metadata. User data is the data from the user's environment that they want to track. Metadata is data about the structure of the database. Indexes and other overhead data are structures that the database uses to improve performance.
