Synthesis of MOF, MDA, PIM, MVC, and BCE Notations and Patterns
Exactly one year ago my first paper in US ? (see liflet)
Abstract
Publications, including academic handbooks, contain numerous inconsistencies in the descriptions of applications of architectural methods and patterns hidden under the abbreviations such as MOF, MDA, PIM, MVC, BCE. An efficient analysis and the following software design, particularly when we are speaking of projects realized in large teams, requires standardization of the production process and the applied patterns and frameworks. This study attempted to sort out the system of notations describing this process and used to describe architectural patterns. Analysis of key notations?MOF and MDA, patterns MVC and BCE?was carried out, and a consistent system combining them into a whole was created.Chapter Preview Top
Background
In this study, Object Management Group notation systems have been used. MOF (Meta Object Facility) specification describes three abstraction levels: M1, M2, M3 and level M0 that is real items (OMG MOF, 2016). M0 is a real system, M1 level is abstraction of the items of this system (its model). Level M2 comprises of relationships between classes of these objects (names of their sets) that is system metamodel. M3 level is a meta-metamodel describing the modeling method with the use of named elements with specified semantics and syntactic.
The analysis and design process is based on the MDA (Model Driven Architecture) specifications. This process has three phases understood as creation of subsequent models: CIM (Computation Independent Model), PIM (Platform Independent Model), PSM (Platform Specific Model) and code creation phase. The CIM model is documented with the use of BPMN (Business Process Model and Notation) (OMG BPMN, 2013) and SBVR notation (Semantic of Business Vocabulary and Rules) (OMG SBVR, 2017). These are, respectively: business process models and notation models and business rules. PIM and PSM models are documented with the use of UML notation (Unified Modeling Language) (OMG UML, 2017).
Between CIM and PIM models, determination of the list of application services (system reactions) occurs, whose realization mechanism is described by PIM model. The standard pattern used for modeling application architecture is MVC pattern. Component Model of this pattern is modeled with the use of the BCE architectural pattern.
Semiotics vs. UML
Semiotics, as a science dealing with symbols and their meanings, provides us with the tool enabling determination of relationships between an object (thing), its name (expression) and definition of notation represented by the name (or sign, meaning). These relationships are referred to as the semiotic triangle. Figure 1 represents this triangle on the left (OMG SBVR, 2017).
The UML notation (OMG UML, 2017) operates instance classifier and class notations. To the right, Figure 1 demonstrates an equivalent to semiotic triangle expressed with those terms.
The UML notation further operates the general structure notation, which is the content of each correct UML diagram. Structures may express a conceptual model (Namespace) or model (also metamodel) of system architecture (e.g. software) in the form of a chart (Architecture).
