Abstract:Osrednjo temo diplomske naloge predstavlja integracija podatkov v počasi spreminjajočo se dimenzijo, katere podatke s pomočjo procesa pridobivanja, preoblikovanja in polnjenja shranjujemo v podatkovno skladišče. Z orodjem za integracijo podatkov Informatica PowerCenter smo razvili prototipno rešitev za počasi spreminjajočo dimenzijo strank, ki naročajo storitve in za katere želimo imeti na voljo zbirko vseh aktualnih podatkov o strankah, vključno z zgodovino izbranih storitev, za namen analiziranja kupnih navad in profila strank. Rešitev predstavlja elemente počasi spreminjajočih se dimenzij tipa dve, kjer v ciljno tabelo vstavljamo povsem nove stranke, želene atribute prepisujemo z najbolj aktualno vrednostjo oziroma dodajamo zapise z novimi vrednostmi poleg starejših zapisov, za namen beleženja zgodovine sprememb. Orodje Informatica PowerCenter uporabniku omogoča preprosto vizualno modeliranje procesa, ob tem pa optimalno prilagajanje potrebam in spremljanje izvajanja. Za namen testiranja rešitve smo spreminjali vrednosti določenih atributov in opazovali spremembo v ciljni tabeli. Rešitev je primerna za realizacijo v realnem okolju in omogoča hranjenje podatkov v podatkovno skladišče v pregledno in smiselno urejeno zbirko podatkov, pripravljenih za poizvedbe in analizo.

Title:DATA INTEGRATION IN SLOWLY CHANGING DIMENSIONS
Abstract:The central topic of my thesis is the process of integrating data into a slowly changing dimension; the data from it is stored in the data warehouse by means of the extracting, transforming and loading process. With the aid of Informatica PowerCenter software for integrating data, we have developed a prototype solution for the slowly changing dimension of customers who use the services. We wish to have at our disposal the complete collection of all current customer data, including customer history, for the purpose of analyzing their purchasing habits and profile. The solution represents the elements of the slowly changing dimensions Type 2, where new customers are inserted into target tables, the chosen attributes are recorded with the most current values or, alternatively, records with new values are added next to older records in order to track data history. The Informatica PowerCenter software provides the user with the simple visual modeling of a process and at the same time allows for optimum adjustment to given requirements and monitoring the implementation. As a method of testing the solution, we repeatedly changed the values of certain attributes and then observed the transformation in the target table. The solution is suitable for use in the real environment and enables entering the data into a data warehouse to set up an easily manageable and logically organized collection of data that is readily available to search through and analyze.
