“…The support and the correlation itemsets can be employed to prune the weak FD rules. It is concluded that MAR techniques can improve our proposed conceptual schema reverse engineering technique [5] and can be used generally to reverse engineer FDs from XML Databases. …”

“…In addition, [4] captured all of ORM constraints that are still not defined in [1] and used XQueries to detect invalid constraints in XML Databases. Furthermore, [5] proposed reengineering the existing XML Databases using a conceptual schema approach.…”

“…Single Association Rule Mining from XML Data was conducted by [7]. Moreover, [8] studied extracting Association Rules from XML Documents using XQuery [9] In this paper, we employ Multidimensional Association Rule (MAR) to improve the ORM reverse engineering which was proposed by [5]. So far, deriving conceptual schemas from XML Databases using MAR has not been addressed.…”

The more popular XML for exchanging and representing information on Web, the more important Flat XML (XML) and intelligent editors become. For data exchanging, an XML Data with an XML Schema and integrity constraints are preferred. We employ an Object-Role Modeling (ORM) for enriching the XML Schema constraints and providing better validation the XML Data. An XML conceptual schema is presented using the ORM conceptual model. Editor Meta Tables are generated from the conceptual schema diagram and are populated. A User XML Schema base on the information in the Editor Meta Tables is generated. However, W3C XML Schema language does not support all of the ORM constraints. Therefore, we propose an Editor XML Schema and an Editor XML Data to cover unsupported the ORM constraints. We propose the algorithms for defining constraint in the User XML Schema and extending validity constraint checking. Finally, XQuery is used for extending validity checking.

“…ORM has also been used for business rules as a markup language [14] as well as for ontology modelling [26], and reactive behaviour [24] and temporal extensions have been proposed [42,43]. Extensions to ORM's precursor, NIAM [37,38], have also been proposed [44,8,4,55], including a transformation from NIAM into Optimal Normal Form 1 [32,33], a set of rules for schema conversion from NIAM to EER and vice-versa [48], a semantic comparison of the ER model and NIAM [30] and the EER model and NIAM [28], as well as an analytical evaluation of NIAM's grammar for conceptual schema diagrams [54].…”
