Between 1968 and 1988 Codd published over 30 papers on the relational model (RM) - the most famous of which is his 1970 paper. Up to 1978 the papers describe RM Version 1 (RM/V1). In early 1979 Codd first presented some new ideas, called RM/T ('T' for Tasmania), at an invited talk for the Australian Computer Science Conference in Hobart, Tasmania. Later that year the ACM journal published a paper on RM/T, in which Codd acknowledges the influence of Schmid & Swensen (1975) and Wiederhold (1977).

The relational worldview model can best be illustrated with a four quadrant circle representing four major forces or sets of factors, which together must come into balance. These quadrants are context, mind, body, and spirit.

The relational model was invented by E.F. (Ted) Codd as a general model of data, and subsequently maintained and developed by Chris Date and Hugh Darwen among others. In The Third Manifesto (first published in 1995) Date and Darwen show how the relational model can accommodate certain desired object-oriented

Relational evangelism looks to the life and actions of Jesus as the role model. While there are examples from scripture where Jesus did not need a long period of time to “build a relationship” with a person in order to present the Gospel, there are likewise abundant examples of building relationships with people and of taking the initiative in conversations. In the opening chapters of the Gospel of John we see Jesus going to a wedding feast where there were a lot of people, among them, folks who had no idea who He was. I would suggest that many of those people would not have wandered into the temple or in some other way placed themselves near Jesus on their own. He went to where they congregated.

There have been several attempts to produce a true implementation of the relational database model as originally defined by Codd and explained by Date, Darwen and others, but none have been popular successes so far. Rel is one of the more recent attempts to do this.

Oracle8i Spatial supports two models for representing geometries: relational and object-relational. The two models are mutually exclusive. See Section A.1 for a description of how to choose the model best suited for your application.
