Data integration projects are often faced with increasingly complex requirements. For example, new data sources should be quickly connected to existing solutions, data must be readily available, high data quality and flexibility in terms of adaptability are beyond question. In addition, the data supply processes should be robust, repeatable and reliable. Probably every data integration project knows the request for quick customization, which must necessarily work reliably. Such requirements have been and will always be brought to our attention in our everyday project life, which motivated us to develop the supporting tools Gen², Job² und Doc² – powerful and practical Tools, which resulted from our more than 20 years of experience.
