Experience of Designing a Relational Materials Database

Source

This paper describes the design of a database for Engineering and Manufacturing Materials data in a tabular (relational) format. The freedom permitted by a relational (rather than hierarchical) data model allows better use of the computer's ability to handle n-dimensional and complex networks of information.

The following features arc described: • The use of Information Engineering. • The separation of independant variables from property identifiers, to allow extensive scope for storage, interpolation and presentation of complex data. The use of ‘inheritance’ to allow storage and maintenance of generic information (in a manner which is analogous to class-instance object oriented systems). • The capability of holding data of varying quality and for differing applications (design and specification data) within the same database. • The use of direct document publishing. • The integration with company wide systems referencing materials information.

It will be noted that these features arc based on the study of the structure of the materials information and are believed to be generic solutions to the modelling of Materials Property Data.
