Oracle has acquired Endeca, a respected provider of enterprise search solutions. Oracle used their recent OpenWorld event to announce big data offerings, and I can’t help wondering if this deal was meant to be signed in time to be presented as part of that package. Arik Hesseldahl notes that financial terms have not been disclosed, with Leena Rao reporting that the company had previously raised $65 million in investment from various sources. Endeca co-founder Daniel Tunkelang (now at LinkedIn) appears pleased by the deal, but it remains unclear how easy it will be to integrate Endeca’s software into the Oracle product family. Mind you, the same could just as easily be said for HP’s comparable acquisition of Autonomy.
