The business intelligence procedures aim to support management decision-making with processing of information. These tools include data mining, data warehousing, decision support systems, and other real-time analytical processes. Data warehousing provides the data are stored in the form needed to produce ad-hoc reports.
Aim of the thesis is to develop a data warehouse and analyze the stored data, and create reports with Oracle BI Answers. For this task I process a meteorological database that provides daily updated radiosonde measured data using meteorological balloons globally at more than 1,500 stations. During the work I plan the data model for the basis of the data warehouse and the reports based on it. Furthermore I implement a program which is suitable specially for retrieving, processing and loading of these source data files, which enables automatic processing and loading of data to data warehouse, and thus keeps the data warehouse on daily updated. After that I implement the reports, and analyze the data on graphical interface.
