Project approach to software development Sanja Čandrlić, Martina Ašenbrener,

About the presentation A short overview of educational model in area of business software development This model provides basic knowledge in business process analysis, data modeling, reading models, participation in software development teams Related to several courses at undergraduate and graduate level Department of Informatics University of Rijeka Experiences 213th Workshop SE Education and Reverse EngineeringBansko

Introduction Project approach is common in software industry At faculty level – experiencing and understanding activities and phases during software development Following chosen methodology 313th Workshop SE Education and Reverse EngineeringBansko

The basic idea To give an overview of IS and SW development phases To teach each develoment phase in a separate course in detail A group of courses was developed Knowledge about strategic planning, process modeling, data modeling, programming,... Verification and validation? 413th Workshop SE Education and Reverse EngineeringBansko

MIRIS Methodology for Information System Development Metodologija za razvoj informacijskih sustava Basic hypothesis – system decomposition It prescribes phases of development and activities within a particular phase, defines relations between particular activities and sequence of activity execution published th Workshop SE Education and Reverse EngineeringBansko

MIRIS (2) MIRIS uses 3 basic methods: data modeling method, process modeling method and application modeling method 613th Workshop SE Education and Reverse EngineeringBansko Logical modeling - design Phase 1: STRATEGIC PLANNING OF IS Phase 2: MAIN PROJECT Phase 3: PROJECT REALIZATION Physical modeling – building Phase 4: SOFTWARE REALIZATION Phase 5: IMPLEMENTATION AND APPLICATION Phase 6: MAINTENANCE Why? What? How?

Information systems course 2nd year of undergraduate study Introduction to IS and SW development MIRIS methodology in detail, other methodologies Practical part – seminar about a chosen IS –front office of a bank, insurance agency,... –pharmacy –shipyard –store –city library – th Workshop SE Education and Reverse EngineeringBansko

Information systems course (2) Gathering and analysis of documents used in the system (internal, input, output) Analysis and understanding of the data in each document Invoice, invoice number The first step in analysis; starting point for the courses that follow 813th Workshop SE Education and Reverse EngineeringBansko dataexample data type and length description Invoice number S10 the year the invoice is issued in and the ordinal number of the invoice in that year

Process modeling course 3rd year of undergraduate study (winter sem.) Related to the second phase of the development To perform interviews and meetings with the representatives from inside the system Structured Systems Analysis 913th Workshop SE Education and Reverse EngineeringBansko

Process modeling course (2) Student papers include: Data flow diagrams (several levels) Context diagram Hierarchy of the system representation diagrams – function tree of the processes Process description More detailed view of the business system: An abstract model of the entire system Deviding of the system into subsystems Models of subsystems 1013th Workshop SE Education and Reverse EngineeringBansko

Data modeling course 3rd year of undergraduate study (summer sem.) Related to the third phase prescribed by MIRIS Entity – relationship method Student papers are complex data models based on the documents gathered: Entity – relationship diagrams Relationship representation of the database Improved for final papers and final exams 1113th Workshop SE Education and Reverse EngineeringBansko

Introduction to software engineering course 3rd year of undergraduate study Practical part - the basis for further work on SW development To use the capablities of the chosen CASE tool for business SW development The development itself will take place in the SE course one year later Programming in several other courses independently 1213th Workshop SE Education and Reverse EngineeringBansko

Software engineering course 1st year of graduate study More professional view on business systems Implementation of the knowledge about models, metamodeling, design of SW specification, cost analysis, team SW development Presentation of student SW applications Teams can compare their independent work 1313th Workshop SE Education and Reverse EngineeringBansko

Information system of an organisation course 2nd year of graduate study Design of SW architecture model The method for modeling called Software Product Architecture (APP – Arhitektura Programskog Proizvoda) An original method relying on DFD and ER methods Capability to estimate the best solution for a business application 1413th Workshop SE Education and Reverse EngineeringBansko

Strategic planning of IS course 2nd year of graduate study First phase of SW development, according to MIRIS Taught later because of its complexity - students have to grow The importance of working with users Defining the priorities of a business system, establishing the need for further IS development Identifying gaps in the process and estimating business applications level of support to business processes th Workshop SE Education and Reverse EngineeringBansko

Conclusion – list of courses Information systems course –Mandatory course at the 2 nd year of undergraduate study Process modelling course –Mandatory course at the 3 rd year of undergraduate study Data modelling course –Mandatory course at the 3 rd year of undergraduate study Introduction to SE course –Elective course at the 3 rd year of undergraduate study SE course –Mandatory/elective course at the 1 st year of graduate study Strategic planning of IS course –Mandatory/elective course at the 2 nd year of graduate study IS of an organisation course –Elective course at the 2 nd year of graduate study 1613th Workshop SE Education and Reverse EngineeringBansko

Conclusion – list of assignments Choosing a company and analyzing their documents Process model: data flow diagrams, process tree, process analysis Data model – entity relationship diagrams Software specification, cost analysis Software architecture model Business application development Priorities and process analysis 1713th Workshop SE Education and Reverse EngineeringBansko

Conclusion The task of SW development is divided, parts studied through several courses SW development during several semesters Feeling of accomplishement The final result is complex and made with complete understanding Option – do it all in one or two courses – fast and superficial 1813th Workshop SE Education and Reverse EngineeringBansko
