Latest News: NSI changes to CURSOR-XPS

We have combined our service and support capabilities for high-performance databases with the system-oriented tool development of Nonne & Schneider.

Starting July 4th, 2024, you can find us under one roof: CURSOR Expert Solutions GmbH.

CURSOR Expert Solutions will seamlessly continue all business activities of Nonne & Schneider, but will also take over the development of the CURSOR Admin-Scout. Our extensive portfolio of services and support will in future be offered via CURSOR Expert Solutions.

This consolidates our expertise in Solution Management, both personnel-wise and organizationally, at one location. The executive board will be expanded with Erik Stahlhut, and „XPS“ will remain as a subsidiary within the CURSOR Software AG group in Giessen.

For customers and partners of CURSOR Service Distribution, initially, little will change. All active contracts and agreements remain valid. Your points of contact do not change.

All service offerings available on our website will continue to be available.
The contact details remain the same, just get in touch with us.

About us

the CURSOR Service Distribution

  • High-Value Service Provider for IBM Informix.

  • Distribution for IBM Data-Management Software (OEM/ASL/ESA licensing for ISVs).

CURSOR Service Distribution is a business unit of CURSOR Software AG, resulting from the acquisition of the Informix and development tool specialist "Nonne & Schneider" at the end of 2005.

We offer extensive technical services for IBM Informix, and as a high-value service provider we are the direct contact for all our customers' service needs for these databases.

Our services are independent from licensing through our company. Well-known customers rely on our monitoring and use our tools, while licensing and update maintenance are contracted directly with IBM.
