This paper is a research of problem which was faced during development of clinical information system. This is a scope, where one clinical test can by characterised by several hundreds of attributes. Thus the focus is on the design and performance of database tables with 200-300 columns. To perform the research the Oracle Database Management System was chosen. There is the main factors, influencing performance, such as principles of data storage on disk, query processing also the main facilities to improve performance observed. Based on the basic principles of relational database design some alternatives to tables with many attributes were created. It is normalized and denormalized structures. There is performed the experiment to see how the speed of most used queries depends on data structure. Also there is done the analysis of complexity and usability of these queries.

Nowadays there are lots of information systems for management of production such as CIM (Computer-integrated manufacturing systems), MRP (Material requirements planning systems), MRP II (Manufacturing resource planning systems), ERP (Enterprise Resource Planning systems). All these systems have huge possibilities. However the licence prices are enormous, the software requires big computer capacities. So they are more usable for organizations with big annual turnover. Small companies need programs which allow to collect data, store it, systematize, quickly get required information. Study object. Information system for management of clothes production orders. Study goal. To create information system for management of clothes production orders using up-to-date computer technologies. It was made analysis of organization (producing clothes) computerizing field, described functional and non-functional requirements for IS. Also made comparative analysis of information systems for management of production, project of information system for management of clothes production orders which architecture is client – server. Prepared documentation for users. Made testing and quality control. In future the functionality of the information system for management of clothes production orders can be expanded including calculations of material and production cost.

Valstybėms tiesioginių mokesčių srityje išlaikant suverenitetą ir laisvai nusistatant tiesioginių mokesčių rūšį, bazę, tarifą, apmokestinamus subjektus, atsiranda esminiai skirtumų, sukuriančių rinkos fragmentaciją ir didelių kliūčių efektyviam Bendrijos vidaus rinkos funkcionavimui. Visa tai ir atsilikimas nuo kitų sričių harmonizavimo lemia integracijos poreikį ir spaudimą valstybėms narėms harmonizuoti. Tačiau tiesioginių mokesčių pozityviosios integracijos bazė reikalauja, kad Taryboje priimant direktyvas būtų sprendžiama vieningai (nuo 2004 m. – 27-ių valstybių konsensusu). Tai de facto blokuoja privalomų teisės aktų leidybą ir sukuria politinių sprendimų stagnaciją. Priešingai nei pozityvioji integracija, negatyvioji integracija (daugiausia besiremianti laisvo judėjimo pažeidimų draudimais), vyksta itin sparčiai, nepaliaujamai didėjant ETT sprendžiamų bylų ir jų ratio decidendi sklaidą užtikrinančių Komisijos pažeidimo procedūrų skaičiui. ETT, spręsdamas bylas, taiko „visaapimantį” požiūrį: vertinant vienos valstybės įstatymų atitiktį EB teisei, analizuojami ne tik jos įstatymai, bet ir kitos, susijusios valstybės, įstatymai bei jų tarpusavio dvigubo apmokestinimo išvengimo sutartys, t.y. aplinkybių visuma, todėl netgi tas pats įstatymas santykyje su valstybės A įstatymais gali prieštarauti EB teisei, o su valstybės B – jau nebe. Tokia doktrina remiasi Cassis de Dijon abipusio pripažinimo principu: valstybė turi atsižvelgti į kitos valstybės įstatymų nuostatas; tačiau...

These differencies and the gap between harmonization in direct taxes and other spheres stipulate the need of harmonization and pressure for the Member States. However, the sole harmonization base requires the Council to act unanimously (starting from year 2004 – by consent of 27 states). This de facto blocks the law-making of compulsory acts and leads to stagnation of political decisions. Contrary to positive integration, negative integration (mostly founded on prohibitions to restrict free movement) proceeds rapidly, while in the meantime the number of cases solved by European Court of Justice (ECJ) and infringement procedures initiated by Commision which ensure the spread of ECJ cases’ ratio decidendi is constantly growing. ECJ when providing the decisions applies overall approach: evaluation of one Member State’s laws means taking into account the whole situation, including the laws of other related Member State and their inter-tax treaties. Therefore the same law is liable to be restrictive in relation to the laws of Member State A, but not restrictive in relation with the laws of Member State B. This doctrine is based under the Cassis de Dijon principle of mutual recognition: Member State is obliged to consider... [to full text]
