Data warehousing biz Teradata has flung a sueball at SAP, alleging the German ERP giant undertook a "decade-long campaign of trade secret misappropriation, copyright infringement and antitrust violations".

Teradata claims that SAP used its strong position in ERP to "lure" the US biz into a joint venture back in 2008 and alleges it then took the opportunity to accumulate the info necessary to "quickly grab market share" in data warehousing.
