Procedural languages for database queries and updates
1990
Journal of computer and system sciences (Print)
Preserved Fulltext
Relational database transformations, encompassing database queries and updates, are studied. ...
A completeness criterion for database languages is introduced, based on their capability to express database transformations. ...
ACKNOWLEDGMENTS The authors thank Ashok Chandra, Erik Simon, and Moshe Vardi for useful discussions on this paper. ...

The SBQL Views prototype is implemented on top of the SBQL query language for the XML DOM model. ...
The prototype follows a novel approach to view updates based on the Stack-Based Approach to object-oriented and XMLoriented query languages. ...
No similar solution exists for objectoriented and XML-oriented databases. ...

In our solution we use the stack-based approach to query languages, its query language SBQL, updateable object-oriented virtual views and the query modification technique. ...
Then, in the resulting SBQL query the wrapper looks for patterns that correspond to optimizable SQL queries. Such patterns are then substituted by dynamic SQL execute immediately statements. ...
In our opinion, the Stack-Based Approach and its query language SBQL offer the first and universal solution to the problem of updateable object-oriented database views. ...

We present an approach to updateable XML views, which is based on the Stack-Based Approach to query languages. ...
Due to procedures we support full algorithmic power of view definitions, which is essential for writing sophisticated wrappers and mediators. ...
The information has a form of procedures (written in a query language) which dynamically overload generic view (updating) operations. ...

The model is based on updateable object views built within the stack-based approach to objectoriented query languages. ...
The model of overloading views is a facility allowing the programmer to separate some kinds of crosscutting concerns that occur during design, implementation and maintenance of database applications. ...
For these models we have defined and implemented the query language SBQL (Stack-Based Query Language), which is much more powerful than ODMG OQL [13] and XML-oriented query languages such as XQuery ...

The approach is based on a very simple and universal architecture and on the stack-based approach (SBA) to object-oriented query languages. ...
Views are used in two ways: (1) as wrappers of local servers that adopt local schemata to the federated database requirements; (2) as a facility for intelligent data integration and transformation into ...
Views are defined in the query language SBQL that is integrated with imperative constructs (e.g. updating) and abstractions (functions, methods, procedures). ...
