A new generation of data sets became available recently in the research data centres of the German statistical offices. These new data combine information for firms gathered in different surveys (or from other sources) that could not be analyzed jointly before. This paper offers a short description of these data, and gives examples of their use to demonstrate their research potential. Furthermore, and looking ahead to the next generation of data, it discusses an ongoing project, KombiFiD, that will for the first time offer access to linked firm level data collected by different data producing public institutions.

This article reports on the influence of the enterprise type on the purchasing decision process within selected product types and phases by using analysis of variance on data from Greek manufacturing and utility enterprises. Our study examined the influence of enterprise type on four parameters of the purchasing decision process, across two different product types and four phases of the purchasing process. The results suggested that all but one parameter varied considerably among the different types of enterprises, and that companies adopt an appropriate structural configuration, which fits to the attributes of the purchased items and the mission of the enterprises.

Purpose The purpose of this research was to determine the dominant type of economic activity of the multi-activity European tourism enterprises. Moreover, the level of internationalisation of the multi-activity tourism firms was verified.Design/methodology/approach The research was performed in the European Union The subjective scope covered tourism enterprises listed on the main markets of the stock exchanges participating in the World Federation of Exchanges or the Federation of European Securities Exchanges. The data was gathered in the fourth quarter of 2014. Findings. The research confirmed that most of the multi-activity tourism enterprises in Europe are focused on the hotel, casino and other activities Moreover, most of them operate internationally Research limitations Firstly, the tourism companies listed on alternative markets were not included into the sample Secondly, other important markets of Asia and North America were omitted Originality/value. The author attempts to fill the research gap concerning the dominant types of economic activity of the multi-activity European tourism enterprises.

The growing interest in business integration and interoperability of IT systems led to an increase in the importance of Service-Oriented Architecture (SOA), which provides tools for Enterprise Application Integration (EAI). In this sense, Enterprise Service Bus (ESB) provides technical capabilities for communication between IT systems. The aim of this article is to present the results of performance tests of selected ESBs of Open Source type. The basis for our performance analysis was a business case of the order realization in the Internet shop of electronics retailer. The order realization requires a collaboration of three IT systems. The business case has been implemented with the use of each selected ESBs: WSO2, Mule, and Talend. Test scenarios were defined and performance tests were conducted for each of the three selected ESBs. On the basis of the collected results it can be concluded that each service bus has its own strengths and weaknesses. Focusing on the merits it should be noted that WSO2 copes very well with files of small size, for small number of users, and also does not burden the CPU significantly. Results for Talend ESB, show that it does well with both kind of files, small and large sizes, for large number of users, but harder utilizes CPU. Research shows that it is worth to analyze the parameters of transmitted messages while selecting ESB for building integration solution. The results show that the Talend ESB may be a good choice for construction of integration solution in a business environment with a large number of users and diversified communications.

Corruption is a phenomenon that manifests in various types and forms especially among operators of Small and Micro Enterprises (SMEs). Many actions of the operators which constitute corrupt practices often tend to be overlooked in spite of their grave consequences for the success SMEs in Nigeria. The fight against corruption in Nigeria is more concentrated in the formal sector. This study was, therefore, designed to investigate various forms in which corrupt practices are carried out among Small and Micro Enterprises in Ibadan, Nigeria. Business owners, their employees, apprentices and consumers constituted the study population. Primary data were collected using questionnaire administered on 200 business owners, 150 employees and 150 apprentices randomly chosen in five business districts in Ibadan; and the conduct of 10 in-depth interviews with purposively selected participants. Quantitative data were analysed at uni-variate level using simple percentages and frequencies while qualitative data were content analysed. Findings from the study revealed that corrupt practices were rampant among actors in SMEs and the common types of corrupt practices included stealing (60%), deception of customers (78.4%), tax evasion (62%), sale of fake products (76%), sale of expired products (65.2%), tampering with measurement scales (69.6%), bribery (82.4%), and poor service delivery (73%). The study concludes that the level of corruption in SMEs calls for concern and government should extend the fight against corruption to the informal sector in Nigeria.

The article substantiates approaches to making decisions of obligations management in the conditions of increasing the assets by types of economic activity in Ukraine. The possibility of using correlation-regression analysis to determine the most favorable variations (in relation of density) between the effective indicator (types of assets) and production factors (types of liabilities) has been proved. A method of analyzing the operating environment is applied to identify the shortest possible reduction in current and long-term liabilities and maximize the volume of current assets. It was found that (i) the most efficient type of economic activity due to the increase in current assets in Ukraine was administrative and support service activities (0.90), the least efficient – agriculture, forestry and fisheries (0.47); (ii) education and training activities (0.93) are the most effective types of economic activity due to reduce liabilities, and health and social assistance (0.44) are the least effective. The results of the study can be used in planning the sustainable development of different types of economic activity.
