MDSphere (Market Data Sphere) is a platform from Unitek Engineering AG for managing data feeds centrally, mainly market data from external providers. According to the vendor, it acts as a proxy and control layer between data providers, internal sources and applications. External and internal sources are merged into one customer-specific data model, including mapping, normalisation and golden-record logic. You can choose the source per field or category, even without changing the consuming systems. Central caching reduces requests, and every request is logged by source, field and user. That shows who uses which data at what cost.
Unitek Engineering AG is headquartered in Zurich, Switzerland. Switzerland is not an EU member state but an EFTA country with an EU adequacy decision. The pages consulted do not state whether MDSphere is delivered as SaaS, in the customer's own environment or otherwise, where data is hosted, or who owns the company. Ask the vendor about this. The platform itself is designed to reduce dependence on individual data providers.
