2 DATABASE TECHNOLOGIES Data is a set of information obtained as a result of processes, experiments, processing data etc. accumulated and represented in a machine-readable format. Data may contain useful information as well as noise, "garbage" because the usefulness is associated with the subject that uses the information. Thus, the term "data" is closely connected with the following problems: Transformation of received data into the machine-readable format; Data pre-processing; Accumulation and storage of data; Provision of data integrity, security reliability; Data access interface; Data warehouse modelling; Analysis tools for the collected data; Tools for search and retrieval of useful information; Inverse transformation of data and/or information based on these data from the machine-readable format into the user-friendly interface. In addition, as a result of the dramatic growth of the accumulated data, there are other problems: 2 Data ordering; Provision of reasonable performance for all kinds of data manipulation (load, converting, processing, retrieval etc.); Big Data storage; Distributed data (Shared Nothing) and load balancing; Data Marts; Data Warehouses; Data Mining; Predictive Analytics; Business Intelligence; Conflict resolution of competitive access simultaneously to a large number of processes; Recovery of lost or corrupted data. Most modern databases cover the majority of the indicated issues, although not all of them. But once there is a need to divide the work into the database administration, design of data

3 structure, programming of data manipulation. Moreover, the more complex a system is, the more and more qualified specialists are required.

4 OIL ORDER Oil Order is a system that can handle the bidding on fuel orders. The customer makes an order of a selected fuel, specifies the volume and the delivery address as well as the degree of the tank filling. Fuel suppliers can then see the order and put a price for fuel delivery. Winning bid is confirmed to the customer by the supplier entering last date of delivery. Administrator sets up and approves new customers and connects new suppliers. 4 Development Tools: Microsoft Visual C# Databases: MS SQL 2012 ( ), PostgreSQL Programming languages: ASP.NET MVC 5 and C# 4, T-SQL, PostgreSQL.

9 FINANCIAL WORKFLOW (PILOT) This project was a preliminary step of the application of risk management for investment companies. The WPF, MVVM, WCF/Web Services, MS SQL 2010 technologies were chosen because WPF (+ WCF/Web Services) has richer graphic features compared with SilverLight. 9 Development Tools: Microsoft Visual C# Databases: MS SQL Programming languages: C#.NET, T-SQL. Extras: Using MVVM and WPF/ SilverLight technologies, WCF/Web Services.
