Veiklos modelio taikymas vartotojo reikalavimų specifikacijos generavime. / Enterprice Model Based Generation of User Requirements Specification.

Kuriant informacines sistemas ir siekiant jas geriau pritaikyti verslui, pastaraisiais metais vis daugiau dėmesio yra skiriama vartotojų reikalavimų specifikacijai. Vartotojų reikalavimus galima specifikuoti pasinaudojus sistemos reikalavimų specifikacijos (SRS) šablonu, tačiau bet kurį SRS šabloną vis tiek reikia pritaikyti kiekvienam individualiam projektui. Šioje reikalavimų inžinerijos stadijoje susiduriama su problema, nes dar nežinant kokie bus vartotojų reikalavimai reikia pasirinkti tinkamą SRS šabloną bei programinę įrangą. Ne visi šablonai yra suderinami su individualiomis programomis ir ne visos programos pasižymi tomis pačiomis savybėmis. Kadangi šiuo metu nėra būdų, kurie padėtų išsirinkti tinkamą projektui vartotojų reikalavimų specifikacijos įrankį, šiame darbe toks būdas bus kuriamas ir aprašomas. Problemos ištyrimo lygis. Šiuo metu visos sukurtos informacinės sistemos (t.y. vartotojų reikalavimų specifikavimo (VRS) įrankiai) yra skirtos reikalavimams specifikuoti žinant specifinio projekto reikalavimus. Įrankio, kuris leistų pasirinkti tinkamą VRS įrankį, nėra. Darbo objektas: vartotojų reikalavimų specifikavimas. Darbo tikslas: sukurti būdą, kuris leistų pasirinkti tinkamą vartotojų reikalavimų specifikavimo įrankį. Siekiant užsibrėžto tikslo, yra sprendžiami tokie uždaviniai: • išnagrinėti sistemos reikalavimų specifikavimo (SRS) šablonų sudėtį; • atlikti SRS šablonų analizę, nustatyti jų savybes, privalumus bei trūkumus; • išnagrinėti vartotojų reikalavimų...

Kaunas: Vilnius University, Kaunas Faculty of Humanities, Department of Informatics. 59 p. S U M M A R Y MBA graduation paper goal is to create a method that would allow consumers to choose the right tool for specifying requirements before knowing them. In order to achieve the goal, following tasks are solved: perform analysis of system requirements specification templates, user requirements specification tools and their compatibility with each other; develop SRS and user requirements specification tools criteria; and investigate a proposed tool with experimental data. Scientific literature, SRS templates and user requirements specification tools summary are used during analysis. The main result of this work is the proposed iVRS tool that solves the problem under investigation, since it allows choosing the exact and correct SRS template and software. This solution differs from existing solutions because it allows users to select the requirements specification tool in the pre-specification stage, where the error price is lowest. This paper also sets out SRS and user requirements specification tool criteria. Paper consists of 59 pages, 14 tables and 19 pictures.

The data modeling phase is one of the main phases in automated system development methods. Usually data modeling is separated as independent process which success and robustness depends largely on the intuition and experience of the data analyst. This can become problematic when IS database is being designed for large scale IS. To solve this type of problems it’s proposed to accomplish data modeling phase not as a separate, poorly with the generic modeling process connected part but as one of the fundamental system development phases. Functional Requirements Specification Method is proposed for this matter. This methods main idea is to build database model according to user requirements for the functionality of the system being developed. The purpose of this work is to present a process intended for building a entity relationship diagram from the analysed functional requirements specification metamodel and generation of the SQL DDL script (relational schema) from that model. The presented model will be implemented as one of the CASE tool modules specified for the database modeling and SQL DDL script generation. Implemented tool will be verified and it’s correctness will be experimentally approved.

In the early stage of building a new informational system requirement engineering involves all the processes related to the requirement system and research of problems emerged during this process. In this stage the requirements specification of corresponding information system are built. Many different notations serve for this purpose, selection of which is dependant on available resources and project goals. Requirements specification must be of good quality. It is evaluated by characteristics of quality. Specifications could be analyzed and improved by using various tools including CASE tools. The specification is developed and its quality is improved by making analysis of requirements. Well done specification is basis for creating high leveled functionality system.
