Tables
Each Gellish Database consists of one or more Gellish Data Tables. Each of those Gellish Data Tables has basically the same structure and is standardized and is application system independent. This is different from conventional databases that usually have proprietary data structures, whereas all database tables are different. Each of the Gellish Data Tables shall contain at least the obligatory columns that are defined in specification document 'Definition of Gellish Databases and Data Exchange Messages'.
The content of Gellish Data Tables can be created conform ISO 10303-221 or ISO 15926 or can be compliant with the grammar and the dictionary of the formal Gellish English language (or a Gellish variant in any other natural language). The standardized tables, in combination with the formal Gellish language, enables to combine an arbitrary number of Gellish Data Tables into one Database. Furthermore, such a database might be centralized, but can also be a distributed database. This also enables to combine the results of a query to various independent data stores, which then act as a distributed database.
The various Gellish Data Tables all have the same core of column definitions. Apart from that core, the tables may also have one or more of the optional columns. Preferred collections of columns are defined in standard Gellish Data Table subsets.
A Gellish Database may be implemented in various formats. It can be in the form of an SQL database, or in RDF/XML, or even in XLS (the form of Excel spreadsheet tables).

Famous quotes containing the word tables:
“Hast thou named all the birds without a gun?
Loved the wood rose, and left it on its stalk?
At rich men’s tables eaten bread and pulse?
Unarmed, faced danger with a heart of trust?”
—Ralph Waldo Emerson (1803–1882)
“Players, Sir! I look on them as no better than creatures set upon tables and joint stools to make faces and produce laughter, like dancing dogs.”
—Samuel Johnson (1709–1784)
“It breedeth no small offence and scandal to see and consider upon the one part the curiosity and cost bestowed by all sorts of men upon their private houses; and on the other part the unclean and negligent order and spare keeping of the houses of prayer by permitting open decays and ruins of coverings of walls and windows, and by appointing unmeet and unseemly tables with foul cloths for the communion of the sacrament.”
—Elizabeth I (1533–1603)
