SUMMARY Project aim – to analyse existing IS of Lithuanian jobcentre and ascertain perfection and development possibilities of it. In reference with results offer suggestions to Lithuanian jobcentre Information system planning department on IS development and potentialities renewal. Organization and information structures and work model of Lithuanian jobcentre was inspected. It was made analysis of jobcentre and compared with other similar search systems. There were marked the mane functional and technological development stages of jobcentre information system. As a result of this analysis it was shown Lithuanian jobcentre information system variation from DBIRZA to DBIRZA_I Users demands on pending IS work processes were investigated and framed out by questionnaire, also Lithuanian jobcentre process modeller by which must be renewed jobcentre IS was investigated. Possible software was reviewed. MySQL technology was chosen for data base build-up and PHP technology for programming. Employer’s information registration and administration also unemployed registration use case modellers were prepared. They detail describes information flows and computerized tasks of system. There were made structural diagrams of information flows. According to information flows the entity relations diagram was created, the logical structure of data base for certificates was developed. The data base Projektas was created for search system. Specification of program modules was made up. Manuals... [to full text]

Perspektyvos atžvilgiu, investavimas yra nesudėtingas ir efektyvus būdas, nepriklausomai nuo pajamų ir gyvenimo būdo, siekti ilgalaikių ar trumpalaikių finansinių tikslų ir įgyvendinti svajones bei norus. Nesvarbu, kas esate ir kiek uždirbate – pasinaudoję investavimo siūlomomis galimybėmis turimus pinigus be jokių pastangų galite „užauginti“ ir leisti savo reikmėms. Sėkmingai išmokus investuoti su virtualiais pinigais, galima bus pradėti investuoti į tikrus investavimo instrumentus – akcijas, fondus, obligacijas ir t.t. ir taip siekti savo gyvenimo tikslų. Pagrindinis šios sistemos sukūrimo tikslas suteikti žmonėms galimybę išbandyti investavimo sugebėjimus ir patikrinti savo investavimo strategijas virtualiai. Ši sistema padės suvokti investavimo principus, bei įgyti bazines žinias apie investavimą, neinvestuojant grynųjų pinigų. Šiame darbe aprašomas projektinis sprendimas, panaudotas kuriant sistemą, architektūra ir svarbiausi realizacijos aspektai. Išskirti panašių sistemų privalumai ir trūkumai. Pasiūlytas būdas, kaip galima išplėsti bei papildyti esamų sistemų funkcionalumą. Sukurtas optimizacinis akcijų biržos lošimo modelis, leidžiantis apjungti virtualų biržos modeliavimą su sistemos naudotojų investavimo strategijomis. Eksperimento metu buvo įrodyta, jog virtuliai modeliuojant akcijų biržą gauti rezultatai ne daug kuo skyrėsi nuo rezultatų, gautų tiriant investavimo strategijas su istorinėmis akcijų kainomis. / Perspective, investing is simple and effective way, regardless of income and lifestyle, to achieve long-term or short-term financial goals, dreams and wishes.

A proposed method to complement and extend the functionality of existing systems. Developed optimized stock gambling model, allowing the exchange of virtual simulations combined with investment strategies of users. In this experiment, it was proved that obtained results of the stock exchange simulation are not much different from the results, obtained in testing the investment strategies of historical stock prices.
