The information system created performs the following functions: standardizes the process of failure registration and management; allows monitoring and receiving information in different sections adapted for certain groups; provides opportunity to evaluate the existing situation of provision with equipment and plan future investments within time scale; allows service of a whole group of users in one time. The information system has been created by using open source software – which enables to avoid additional investments.

The importance of Information Technologies is growing continually. Small and Medium-sized Enterprises (SME) form the large part of Economy of each country. As a whole SME is the biggest client of Information and Communication Technologies in spite the fact they don't carry out big projects as corporate clients. Currently SME is the fastest growing segment of IT market. It contains the biggest number of companies which make IT development and buying decisions by themselves. For SME's, it is not always effective to built their information systems on the base of large standart packages. This Master Thesis demonstrates how to analyze, design and build accounting information system for small enterprise Lumen, producing the stomatologic equipment. The system is implemented using Access 2003 Database Management System and successfully used by Lumen personnel.

In security engineering and computer security, authorization, is a part of the operating system that protects computer resources by only allowing those resources to be used by resource consumers that have been granted authority to use them. Resources include individual files or items data, computer programs, computer devices and functionality provided by computer applications. Examples of consumers are computer users, computer programs and other devices on the computer. Authorization process makes use of the authentication process to identify consumers. When a consumer tries to use a resource, the authorization process checks that the consumer has been granted permission to use that resource. Permissions are generally defined by the computer's system administrator in some types of "security policy application", such as an access control list or a capability, on the basis of the "principle of least privilege": consumers should only be granted permissions they need to do their jobs. Older and single user operating systems often had weak or non-existent authentication and authorization systems. "Anonymous consumers" or "guests", are consumers that have not been required to authenticate. They often have very few permissions. On a distributed system, it is often desirable to grant access without requiring a unique identity. Familiar examples of authorization tokens include keys and tickets: they grant access without proving identity.

The main aim of the project is to develop a 2D and 3D geometrical transformation training program. The goal of research is to analyse geometrical transformation practical usage. The existing geometrical transformation systems and new developed system are reviewed. The object oriented design was used to develop a system. 2D and 3D geometrical transformation viewing, task generating and its solving training system was developed.

School is the most important organization in the process of creating educational community, because there is a place where citizens of this community are raised. Schools computerization gets most attention. Analyzing existing intranet based learning systems and creating system, witch is designed for general education schools to improve their students ant teachers work, are object of postgraduate studies work. This system allow schools to corporate, share information, studying plans and information. Created system can be used in all general education schools. This system can be reused in schools which has special purpose. System is designed for virtual learning and communications between students and teachers, for sharing and using educational information, for analyzing marking and learning results, creating summaries. Teachers can: • create studying plans; • deliver theoretical educational information; • create tests; • mark students work at lessons and tests. Students can: • use educational information, which teacher offer them; • communicate with other students and teachers; • take tests; • check for their marks. System can be useful for parents of students. Trey can check their child marks from their home.

In this thesis are analysed correctness for verification ability of UML activity diagrams by using hypergaphs. There suggested the transformation from UML activity diagram to hypergraph and verification algorithm of hypergraph, which can be used for expanding the capabilities of CASE tools for workflow and e-business modelling.

In theoretic part of the postgraduate final work, there are analysed administrating and management problems, desirable objects of the school. Considerating software, that will be used to create system. Reviewing similar existing products. In practical part , the created system is descriptive, it‘s operations, user settings, testing results, problems that came during the development process and conclusions.

In early 60-ies of XX th century the computer is born and begin to inculcate in various range of life. Text data have been changed into digital databases. In late nineties computers becomes concurrent with our daily life. In year of 2001 government begins to fund computerizing of secondary schools in Lithuania. According, to analysis of situation in secondary schools computerization, we can admit that the level of computerization is high. Situation with geography computerization is quite comfortable too. It is good situation to begin apply GIS to secondary education. In year of 2002 a document of “Geography education standards for secondary schools” was realized, and GIS, as a part of geography, has his place in this document. Talking about textbooks of geography, it is only one of them that includes information about GIS (prepared by David Waugh), but considering to geography standards, to form informational skills of students, information about GIS in this textbook is insufficient. Looking for information about GIS we regarded of qualitative information standards, that is set by Education evolutionary centre. Information about GIS is divined into several rubric, they are: definition of GIS, history and birth of GIS, shape of data used in GIS, usage of GIS in modern world. It is important to overview all of those rubric as a main information that is needed to gain a modern calibre of geography. Introduction to GIS programs is important too. Because, at the moment, we don’t... [to full text]

This document is a graduation paper for KTU remote master studies of Information Systems. Information system for forestry department bookeeping described in this paper uses client-server architecture. Data are stored in MS SQL server. User interface is created using Visual FoxPro. The program can be used to perform a part of bookeeping tasks of forestry department . It works either in local network or internet access to the database .

In current work problems and requirements for demand forecasting in commercial or manufacturing enterprises are analyzed and suitable forecasting algorithms are proposed. In enterprises with multidimensional and heterogeneous demand it is advisable to use different algorithms for different demand constituents and to readjust parameters used for forecasting. Existing forecasting packages are not practical as they are not integrated with commodities or materials supply orders management activities and business processes of enterprise. The orders management system is developed with forecasting component using adopted time series forecasting techniques such as moving average, exponential smoothing, double exponential smoothing. These techniques ensure reliable forecasting results for different time series models: random, trend and are integrated with other business management activities. It is possible to calculate deviations of forecasted demand from factual values, to select algorithms giving minimal perсentage error, and to adjust algorithms parameters to changing demand. The system can help managers to choose forecasting algorithms and to adapt their parameters in the course of time. The system is designed using UML CASE tool and implemented in Microsoft .Net environment using MS SQL Server 2005 for data storage.
