Gellish Expressions in A Gellish Database
A Gellish Database is a database that contains one or more standardised Gellish Database tables. Each such table contains the same predefined columns and is suitable for the expression of virtually any kind of fact such that is computer interpretable and system independent. The table can be implemented as an MSAccess database table, an SQL database table or simply as a standard table in a spreadsheet. The core of a Gellish Database table consists of three columns, just as is the case in RDF/Notation 3. Each row with those three columns in such a table expresses a main (binary) fact. For example, the fact that the Eiffel tower is located in Paris can be expressed as follows:
| Left hand object | Relation type | Right hand object |
|---|---|---|
| The Eiffel tower | is located in | Paris |
| The Eiffel tower | is classified as a | tower |
| Paris | is classified as a | city |
The left hand objects and the right hand objects may either be selected from the Gellish English dictionary or may be new proprietary objects that are introduced by defining them on separate lines. If such a new object is an individual thing, then it shall be defined by a classification relation with a class, as is done in the above table and if the new object is a class, then it shall be defined on a separate line by a specialization relation with their direct supertype. The relation types (such as 'is located in' and 'is classified as a') shall be selected from the Gellish English dictionary, otherwise the expression cannot be called standard Gellish, but becomes a proprietary extension of Gellish English.

Famous quotes containing the word expressions:
“Compare the history of the novel to that of rock ‘n’ roll. Both started out a minority taste, became a mass taste, and then splintered into several subgenres. Both have been the typical cultural expressions of classes and epochs. Both started out aggressively fighting for their share of attention, novels attacking the drama, the tract, and the poem, rock attacking jazz and pop and rolling over classical music.”
—W. T. Lhamon, U.S. educator, critic. “Material Differences,” Deliberate Speed: The Origins of a Cultural Style in the American 1950s, Smithsonian (1990)
