Partner announcement on Finextra with Vhayu and Streambase coming together:

Defining what vendors mean by a "Data Management System" is difficult enough for clients, but in the area of the somewhat fuzzy technology definitions around automated trading it is interesting to see Streambase clarify their offering around CEP (and not database too, which was one of their first messages around bringing real-time and historic data together), and that Vhayu seems to be emphasising its tick database capabilities (and de-emphasising its original perception in the market as a CEP vendor).
