Modern Business Information Systems: Extended ERP components and their integration is a sequel to the first volume entitled Modern Business Information Systems: the Enterprise Resource Planning and its Functions, also published with Lambert. In this volume, authors extended the analysis of ERP systems with other interesting aspects as well as with a study on how the ERP beneficially influences the activity of other professions, this time in the public sector. As such, this new volume highlights other ardent subjects that are strictly connected with ERP, especially Extended Enterprise Solutions such as Customer Relationship Management, Supply Chain Management, Business Intelligence, Service Oriented Architecture, Enterprise Application Integration, and others. The target audience will be mostly our students but, at the same time, anyone interested in this dynamic and continuously evolving domain, which is Integrated Platforms for Business.
