  1. The Integrated Methodology of Pattern-Based Enterprise Application Development and Maintenance Dr. Sergey V. Zykov, Ph.D. State University – Higher School of Economics 6th Central and Eastern Europe Software Engineering Conference (Russia) (CEE-SEC(R)-2010) October 13–15, 2010,Moscow, Russia

  2. The Integrated Methodology of Pattern-Based Enterprise Application Development and Maintenance Heterogeneous EDW engineering – a challenging SE task • The methodology combines formal model and SDK for class-level association-based relationships. • Problem domain features: • heavy data burden - in 2005 total data size of Intel Corp. exceeded 3.2 petabytes (over 120,000 employees in 57 countries) • - high object classes complexity • - incomplete information on the structure of certain instantiations of the classes; • - the set of class attributes and operations can be determined rigorously. • Reasons for methodology application: • - variety of heterogeneous classes, • - importance of association-based inter-class relationships • - class inference possible even under certain % of weak-structured class instances 6th Central and Eastern Europe Software Engineering Conference (Russia) (CEE-SEC(R)-2010) October 13–15, 2010,Moscow, Russia

  3. The Integrated Methodology of Pattern-Based Enterprise Application Development and Maintenance The methodology vs. ontology-based approaches (OBA): • OBA (e.g. Cyc) efficiency is comparable only under a total class-level uncertainty, which is a different problem domain than ECM • Thesaurus needed for the OBA to meet the relevance required • The methodology uses similar foundations and tools as OBA (UML and XML-based tools, predicate calculus-based CycL, “conceptual model” etc.) for data modelling and integration • OBA lack a balanced combination of formal models and industry-level SDKs (incl. visualization) for ECM lifecycle, resulting in low scalability and non-suitability for the major enterprise-level tasks 6th Central and Eastern Europe Software Engineering Conference (Russia) (CEE-SEC(R)-2010) October 13–15, 2010,Moscow, Russia

  8. The Integrated Methodology of Pattern-Based Enterprise Application Development and Maintenance Problem domain modeling Data object modeling: “classobjectvalue” Class– collection of data objects of the integrated problem domain; Object– class instantiation by CMS template (metadata partial evaluation); Value– static HTML page generated by CMS (full evaluation). Benefits: - evolves from the object-oriented approach; - develops the existing models ([V.E.Wolfengagen’sCM] et al.) in relation to global computational environment 6th Central and Eastern Europe Software Engineering Conference (Russia) (CEE-SEC(R)-2010) October 13–15, 2010,Moscow, Russia

  9. The Integrated Methodology of Pattern-Based Enterprise Application Development and Maintenance Modeling classes of data objects ClassesCof problem domain data objectsare modeled by domains: C = Iw:[D]  v:D (w(v) ) = {v:D|},where: 1) CandDare in a partial order relation (C ISA D); 2) is a criterion of data object wbelonging to class C from the viewpoint of a problem domain expert. Class of “n-dimensional”data objects is modeled by an n-arity relation: Rn = Iw: [V1,..,Vn] v1:V1 … vn:Vn (w [v1,…,vn]) = {[v1:V1,…,vn:Vn] | }, where:  – “n-dimensional”criterion of data object wbelonging to classRn Classisa collection of ordered pairs (vi,Vi), where vi isits i-th attribute (either of data or of metadata); Vi– attribute type. 6th Central and Eastern Europe Software Engineering Conference (Russia) (CEE-SEC(R)-2010) October 13–15, 2010,Moscow, Russia
