Abstract
This paper classifies a collection of conceptual data models within a taxonomy framework consisting of the following parameters: graph theoretic versus set theoretic models, mathematical foundations, terminology, and semantic levels of abstraction.

The Entity Relationship Model — Toward a Unified View of Data
5,769 Citations2002Peter Pin-Shan Chen
A data model, called the entity-relationship model, is proposed that incorporates some of the important semantic information about the real world and can be used as a basis for unification of different views of data: the network model, the relational model, and the entity set model.
Communications of the ACMA relational model of data for large shared data banks

SEQUEL
576 Citations1976Donald D. Chamberlin, Raymond F. Boyce
The data manipulation facility for a structured English query language (SEQUEL) which can be used for accessing data in an integrated relational data base.
On the semantics of the relational data model
144 Citations1975Hans Albrecht Schmid, J. R. Swenson
A data model is discussed that takes into account basic semantic properties that object types and relationships among them apparently have in the real world, and permits us to analyze the ideas behind the relational theory more precisely, in particular the meaning of functional dependency and normalization.
Communications of the ACMSpecifying queries as relational expressions
100 Citations1975Raymond F. Boyce, Donald D. Chamberlin +2 more
A data sublanguage called SQUARE, intended for use in ad hoc, interactive problem solving by non-computer specialists, and is shown to be relationally complete; however, it avoids the quantifiers and bound variables required by languages based on the relational calculus.
Using semantic networks for data base management
85 Citations1975N. Roussopoulos, John Mylopoulos
This paper presents a semantic model of data bases that assumes the availability of a semantic network storing knowledge about a data base and a set of attributes for the data base.
LSL
38 Citations1976D. Tsichritzis
The purpose of LSL is to provide a compromise between different data base approaches and attitudes, and the hierarchical, network and relational models of data can coexist within the LSL environment.
Specification of stored data structures and desired output results in DIAM II with FORAL
26 Citations1975Michael E. Senko
The primary goal for a specification language is to provide a means for accurate, succinct description of processing algorithms and their related data structures: in effect, a description with a minimum of extraneous detail.
Features of a conceptual schema
9 Citations1975D. Tsichritzis
The conceptual schema comprises a common denominator for all three DBMS approaches: hierarchical, network and relational.
