IntroductionMy article analyzes the IS/IT (Information Systems based on Information Technology) of hotel units integrated into a group, using 'a literature and case study that examines how typical ERP information technology are applied in hotel units with their limitations and advantages. ERP Systems and the Hospitality Industry The push for technology requires a change in the way business is conducted in the hospitality industry. The success of this industry depends heavily on successfully managing the amount of information and timeliness. IS/IT provides the flexibility and efficiency needed by the hospitality industry to understand customer needs [1]. ERP systems emerged as a way to automate recurring processes and provide managers with real-time operations and problem-solving techniques for information disintegration and fragmentation [1]. The need to focus on the problem of information fragmentation is being felt within the hospitality industry [2]. ERP systems are of particular importance due to the variety of applications and systems defined for various functions. This article discusses the problems faced by ERP systems, how the problem was addressed and led the search for answers to achieve the goals. Here are the questions that were addressed in this research. Question 1 – Are all processes of organizations in the hospitality sector covered by ERP systems? Question 2 – What are the limitations of an ERP system and how do they affect business processes? in hospitality companies?Question 3 – What are the main solutions currently offered by the software industry for information integration...... middle of paper ......real-time ion is possible, since the applications with the back-office ERP system are integrated. Temporal integration is therefore a trivial question. Some authors confirm that if support processes applied this form of integration, it would not have a negative impact on any of the critical factors in the industry [13]. The second integration method, service-oriented, forms the interface between the cash management application and the ERP system implemented for the back office. The internal IS/IT team carried out the integration with the web services made available by the supplier of the target application. Real-time integration is done in this case. This does not cause negative impacts. This form of integration has proven to be effective, in the opinion of the authors [10] [14], who argue that Internet technologies are flexible and provide greater ease of implementation..
