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]

Tobulėjant naujosioms technologijoms buvo sukurtos verslo valdymo sistemos (VVS). Su jų atsiradimu gamybos pramonė buvo pakylėta į aukštumas, kokių dar niekad nebuvo pasiekusi. Tačiau taip kardinaliai keičiantis technologijoms organizacijos privalo „sekti paskui jas“, jeigu nori išlikti konkurencingos. Vis dėlto VVS diegimas yra ganėtinai sudėtingas, o ir nuspręsti kokią sistemą diegtis yra dar sudėtingiau. Daugelis diegimo projektų žlugo dėl to, kad buvo nepilnai atlikta poreikių analizė, dėl darbuotojų motyvacijos ir atsidavimo ar dėl neteisingos VVS pasirinkimo. Šiame darbe bus apžvelgtos pagrindinės diegimo, pasirinkimo ir darbo su VVS problemos. Bus atlikta pasirinktų VVS palyginamoji analizė pagal nustatytus kriterijus ir sukurtas VVS koncepcinis modelis. / The title of this work is „A comparison of Enterprise recourse planning systems“.
