Data warehouse

Data warehouse (DW) is a structured set of data accumulated from a wide range of sources within a company, used for fast, easy and comfortable reporting and data analysis. DW provides cleaned and sorted data, which are always available in many different combinations. DW combines historical and operative data, data from social networks and sensors and so on. Data can be loaded to DW either in real time or by nightly updates. Thanks to DW, accessing the data which is needed easier, faster and flexible.

Reporting and data analysis systems

The system of data analysis (may exist independently or be part of a data warehouse) creates a flexible environment for analyzing and visualizing data, for predicting future trends, and making forecasts. Additional benefits include clearer business processes, unified terminology and unified interpretation of data.

Performance management systems

The base of the performance management system is the Balanced Scorecard (BSC). This is a method of management, which relates the daily activities of a company to its vision and strategic goals through a selection of carefully selected performance indicators (measures). For selecting the key performance indicators, the performance of a company is evaluated from four different perspectives: financial management, clients, business processes, personnel, and development of the company. The system gathers information about the most important performance indicators from departments or business areas to a central dashboard.

Data quality analysis and systems

There are always biases and numerical inconsistencies in data, which have an influence on the values of management decisions and the development of the entire organization. These must be identified, analyzed, and fixed or hidden before a report is produced. Data quality analysis gives a good review of data and potential data errors in the database; analyzes why the data errors occur, and gives suggestions for fixing and reducing their impact. Thought needs to be given as to the data quality analysis before building the data warehouse solutions, i.e. before the data errors start to influence the accuracy and usefulness of data analysis reports. The value of seeing the current picture and possible problems with the data gathered in the organization, obtained by performing data quality analysis, can be made permanent through implementing a data quality monitoring system.

Statistical analysis and data mining

Data mining is the process of sorting through large data sets to establish important relationships. The purpose of data mining is to find answers to the following questions:

  • Who are the most profitable clients now and who should be in the future?
  • Which clients most likely leave and go over to the competitors?
  • How it is possible to maximize the profit per client?
  • Who are the best candidates for buying new products?

Resta professional consultants and trainers can help you choose and implement software for statistical data analysis and data mining. We can help you form a suitable sample of clients or data, choose a data analysis approach, and use accurate statistical methods to obtain the desired results.

Medical statistics

Clinical trials give the best results when they are carefully planned. The team of Resta will help to put together the plan for the trial and help to estimate how many participants are needed. Using standard data analysis methods for medical statistics, it is possible to find important information from the data. We help to identify suitable approaches for data analysis and the most appropriate statistical methods obtaining reliable results.
