Introducing Custom Language Extensions to SQL:1999
[chapter]
2003
Lecture Notes in Computer Science
Preserved Fulltext
A translator system uses information imported from the packages to translate the statements containing the extensions into SQL:1999-compliant statements. ...
This paper describes the idea of language extensions to SQL:1999 that come in form of independent packages and may be implemented by different vendors. ...
We do not want to present the framework in detail, an excerpt of this framework may illustrate the idea of modular extensions of SQL:1999. The framework consists of different kinds of schema modules. ...

Here we show how that framework provides a mechanism to explore issues of fidelity, integrity and completeness in the design and implementation of an existing object-relational mapping strategy. ...
Using our process we show how our framework helps to identify new issues, understand cause and effect, and provide a means to address issues at the most appropriate level of abstraction. ...
The majority of the solution described in Table IX is possible using the objectrelational features introduced in SQL:1999 ("OR-SQL"). ...

We provide a facility whereby a user delines a view as an SQL select expression, from which the system automatically derives set-oriented production rules that maintain a materialization of that view. ...
It is widely recognized that production rules in database systems can be used to automatically maintain derived data such as views. ...
Views are useful for presenting different levels of abstraction or different portions of a database to different users. Typically, a view is specified as an SQL select expression. ...
