In 1970, Edgar Codd has proposed a more efficient data-storage method--the
relational model. This model was also using SQL to allow applications to find table stored data.
Each
relational model is oriented in opposition to another model, such that the theory includes two pairs of models.

For example, the meta-model for the
relational model (Figure 10), which describes the elements that a relational database schema can have, can be defined at this level.
Both argue--Conrad through a general discussion of Germany's colonial entanglements and Randeria through a focused examination of specifically Indian forms of communitarian civil society--for a
relational model that focuses on mutual and unequal exchanges functioning outside the framework of the nation.
It is understood now that relational databases are not the be-all and end-all, for many purposes a
relational model is not required, inefficient or just counter-intuitive.
A
relational model of spiritual dwelling and seeking (Wuthnow, 1998; Shults & Sandage, 2006) drawing on theology and social science was used to conceptualize this study of spiritual factors hypothesized to be positively and negatively associated with dispositional forgiveness.
We are more concerned in matching schemas of
relational model since this model is the most dominant model and many database applications; especially applications for distributed environment are still adopting this model [7].
(6) Studies in the use of the
relational model became the gender-specific model adopted by the program.
RDBMS is a database system that maintains and manipulates data repository based on
relational model (Codd, 1970).
In this work, a single fuzzy
relational model is used to model both the fault-free and faulty behavior of the system.
