Object Modelling

Garant předmětu:

Lecturer:

Tutor:

Supervisor:

Department of Software Engineering

Synopsis:

Students will practically master conceptual modelling of business structures, they will learn fundamentals of OntoUML notation and methodology. Students will learn fundamentals of pure object-oriented paradigm, i.e. terms object, method, message, class, class instance, composition, inheritance, collections. Students will learn to transform a conceptual model to object-oriented implementation model and they will learn fundamentals of pure object-oriented implementation in Smalltalk and pure object database. Students will learn to formulate rules and queries upon the object database.

Studenti prakticky zvládnou konceptuální modelování struktur businessu, naučí se základy notace a metodiky OntoUML. Dále se studenti naučí základům čistého objektového paradigma, tj. pojmy objekt, metoda, zpráva, třída, instance třídy, skládání, dědění, kolekce. Studenti se naučí konceptuální model transformovat na implementační objektově-orientovaný model a základy čistě objektově-orientované implementace v jazyku Smalltalk s použitím čistě objektové databáze. Studenti se naučí formulovat pravidla a dotazy nad čistě objektovou databází.

Study Objective:

The aim of the course is to explain the fundamentals of the object-oriented paradigm in software development, with emphasis on modelling data objects. Even the best object-oriented programming language cannot ensure by itself that a design will meaningfully and efficiently exploit the object paradigm. Knowledge gained in this module forms the basis for correct application of the object-oriented paradigm in the follow-up modules aimed at software engineering and databases.

The goal of the subject is also to train skills of abstraction and conceptualisation, skills important in software engineering, and also a skill to maintain consistency throughout various model levels from the conceptual through implementation to the programme itself. Students are lead to accurate, correct technical and formal expression.
