Frequently Asked Questions

What does the relational model mean for a database?

The relational model means that the logical data structures—the data tables, views, and indexes—are separate from the physical storage structures. This separation means that database administrators can manage physical data storage without affecting access to that data as a logical structure.

Who is the founder of relational database theory?

Relational database theory, originally proposed by Edgar F. Codd in 1969, is a topic in Computer Science. Codd’s seminal paper (1970) was entitled A Relational Model of Data for Large Shared Data Banks (reference [5] in Appendix B).

How is the relational database t-2frdb built?

T-2FRDB is built by extending ordinary fuzzy relational database models with the fuzzy membership degree of tuples in relations. The management system for T-2FRDB with the querying language like SQL is built by using a classical opem-source mangement system

How are updates performed in a relational database?

Four basic update operations performed on relational database model are Insert, update, delete and select. Insert is used to insert data into the relation Delete is used to delete tuples from the table.
