“…In this section, we will repeat the definition of this constraint and in the Section 4 we will explain the code generator for the constraint validation in the XML DBMSs. The concrete example is the code generation for the validation of the extended tuple constraint, but this way of code generation is also applicable for other constraints we defined in our previous papers [2,9]. It is also extendible since it can be done for every new defined constraint type.…”

“…Here we use ETC type to illustrate how the constraint type characteristics given in [2] can be applied to define ETC by means of the XML data model and how to enforce it in an XML database. We extend [1] with the explanation of the extended XML Schema and the actions in case of violation of the constraint.…”

Extended tuple constraint type as a complex integrity constraint type in XML data model - definition and enforcement

et al. 2018

A database management system (DBMS) is based on a data model whose concepts are used to express a database schema. Each data model has a specific set of integrity constraint types. There are integrity constraint types, such as key constraint, unique constraint and foreign key constraint that are supported by most DBMSs. Other, more complex constraint types are difficult to express and enforce and are mostly completely disregarded by actual DBMSs. The users have to manage those using custom procedures or triggers. eXtended Markup Language (XML) has become the universal format for representing and exchanging data. Very often XML data are generated from relational databases and exported to a target application or another database. In this context, integrity constraints play the essential role in preserving the original semantics of data. Integrity constraints have been extensively studied in the relational data model. Mechanisms provided by XML schema languages rely on a simple form of constraints that is sufficient neither for expressing semantic constraints commonly found in databases nor for expressing more complex constraints induced by the business rules of the system under study. In this paper we present a classification of constraint types in relational data model, discuss possible declarative mechanisms for their specification and enforcement in the XML data model, and illustrate our approach to the definition and enforcement of complex constraint types in the XML data model on the example of extended tuple constraint type.
