Kasri LA, Chenfour N., XML model for relational integrity constraints and complex types, Onl J Bioinform., 23 (2):190-202, 2022. Limits to XML are hierarchical structure and absence of integrity constraints. We describe an XML storage database for management of integrity constraints and object model by typage  created by SQL3 queries. We developed a Java XML framework to map SQL3 and XML to validate stored data in database.


Key words : XML, XML Schema, SQL3, constraints, mapping.
