Rhapsody is a Model-Driven Development (MDD) tool for embedded and real-time system design. The purpose of this thesis is to determine if Rhapsody can be used for software development on small processor platforms such as the Atmel AVR. Rhapsody is normally used on platforms running an operating system. Therefore certain adaptations are needed in order to use it on platforms without an operating system. These adaptations and their affect on the usability of the tool, advantages and disadvantages are all studied while porting AVR-software to Rhapsody on one of CC Systems products, the robust on-board computer CC Pilot XL II. / Rhapsody är ett verktyg för modelldriven utveckling och design av inbyggda system och realtidssystem. Syftet med detta examensarbete är att undersöka om Rhapsody kan användas för att utveckla mjukvara till små processorplattformar som Atmel’s AVR. Då Rhapsody normalt används till plattformar med ett operativsystem behöver vissa modifieringar göras för att möjliggöra utveckling mot plattformar utan operativsystem. Dessa modifieringar, deras för och nackdelar samt påverkan på utvecklingsprocessen undersöks medan AVR-mjukvara porteras till Rhapsody. Mjukvaran som porteras är en del av styrsystemet till en av CC Systems produkter: CC Pilot XL II, en robust fordonsdator.

In this work some progressive object–oriented requirement definition methods were analyzed (ICONIX, Reggio, Scores). Rules and principles of these methods were generalized and comprehensive content of requirements model was presented. Requirements definition must define state and behavior of target information system independently of future design. Requirements model was proposed where use cases are presented as interfaces together with associated classes of problem domain, operations are specified with signatures, pre and post conditions wich must be written in formal language OCL. Model was described using UML class, sequence diagrams, state charts and OCL constraints and is illustrated with examples from case study.

The lack of systematized information about the activity the businessmen are interested in in the region is becoming rather evident nowadays. In most cases only sites of particular organizations with incomplete and unspecified information can be found. The possibility of the creation of a united portal which would enable the businessmen to share the information and increase possibilities of business development is being discussed in this research.

Reengineering of informational systems is reorganization and modification of existing software systems, maintaining then to come easier. In the project action reengineering is suggested as paradigma of alternation at industrial organization which is essential achieving better setting and being more competitionable; influences structures and operations of organization a informational system and its development methods. During this process the present platform of informational system and software is placed. Refering to this rating the ways of software development are planned. Large organizations have functional requirements and demand of informational needs so this project considerates methods how to integrate residual system’s base stages and nero structures, whish are necessary for varied informational needs . Analysed application system’s sphere “ staff accounting” isn’t keel. Its regulation acts are changing, so staff working hours and wages have to conform. Analysed company, with such activity has alternate payment and organizational rules. So chosen way is the most effective. The main problems, noticed at this company: active accounting programme in old operating system doesn’t aberrant activity reasons, old in moral and do not fit all functions. Lithuanian software market is oriented to the West production and has very fero personal accounting systems. They’re coming from abroad Foreing a priori systems don’t fit specified action processes and legal limitation.

The recent stabilization of the Internet is now driving easy aspect of life into an Internet presence and the accompanying e-commerce solutions. In the coming years, the Internet will see growth in numbers unlike the world has ever seen. E-commerce has built itself with this in mind and is making every effort it can to seize the strongest position possible. The idea of e-restaurant extends the restaurant to the web and therefore to the home of customers. It provides the basic services, such as reservation, meal selection, and recommendation. The most appealing thing we found about e-restaurant is its online reservation service. On customer side, customers can take as much time as their need to choose table positions, search menu items, and investigate menu items through pictures, descriptions and feedbacks on e-restaurant's web page before making reservations. Moreover, e-restaurant provides 24-hour reservation service which is difficult for conventional restaurants to provide. On restaurant side, on-line reservation reduces human errors which are not uncommon in reservations by phone. On-line reservation also frees the staff of e-restaurant from repetitive data entry and paperwork. This allows e-restaurant to redirect labor used for back office tasks to front of the house tasks to improve customer service, which is the heart of restaurant business. The Management of e-restaurant can access immediate and up to date business critical data to adjust management strategy in a... [to full text]

SUMMARY Informational system of elementary school community is Informational system, that accummulates and transfers information, inportant for members of school community. System works on intranet and extranet technologies base. The main demand for the system – informational system (IS) should to decrease user‘s time costs presenting end receiveing important information about the spheres of school activity. The main IS users, are administration of the school, teachers, pupils and parents of pupils. The basic IS activity spheres – information about the shcool, it‘s activity, news, links, e – diary and schedules. This document is the documentation of „Informational system of elementary school community“. The documentation reviews the stages of analysis, projecting, program realization and presented summary of user‘s documentation. In the proccess of analysis, were analysed and specified functional and non-functional requirements and limits, that determined IS should be created with the intranet and extranet technology help, using PHP and HTML programming language, InterBase data base, Macromedia Flash and Paint programs. The created IS corresponds to the model of architectural informational system of 3 levels. User‘s link – Activity‘s rules – Data base or TXT files. Informational system is safe. System data is not accessible for strangers. Data is managed by executives of school, that have the access to the system. It is easy to operate the system – to introduce... [to full text]

In this document we are analyzing and modelling Micro Payments Management System (further MPMS). This type of system is based on new technologies. It is created in order to simplify every day’s usual micro payments for different services. All services that require micro payments are integrated into one and single management system. The usage of the created system is simple and easy. The clients of the system are all users that use car parking, city transport, theatre, cinema and other services where you don‘t need big money to pay for services. The users have to have terminal equipment such as: personal computer, laptop with internet connection or cell phone with SMS, WAP, GPRS, 3G functionality or micro-payments card. Payment is very easily done, once you picked a service you can pay buy bank transfer, mobile pay or money is deducted from your virtual account. We think that a lot of service provider will be interested in this type of management system. Also this intellectual micro payments management system will be useful for its users, because you don‘t need special equipment to use it, and this system helps you save your time and money.

Most of an e-commercial systems pay the biggest attention to the acceptance of an orders and maintenance of users ,but the process of performance of the orders ,which are done in the organization, are leaved to the employees. The target of this work was to investigate the system of control of the orders ,which would enable users of internet to make the orders and for the employees of the organization to rule those orders with the help of computer tools. It is possible to work with the investigated system in the firm where it will be implemented and it will be possible to send by internet the program for cost calculation and composition of orders. In the nearest future it would be good to expand the system,upgrade it and to create the web page of the firm.By improving the system some patterns should be included such as the map of the system,the news,perfect the leader and etc.
