It’s no secret that Oracle and SAP have been at each others’ throats for years. For a long period SAP was considered the undisputed king of the world’s largest corporate ERP accounts. But while SAP’s innovation stagnated, Oracle’s inorganic-growth strategy of never-ending acquisitions turned it a very serious challenger to SAP. The competition between the two companies has intensified and grown white hot over recent months.The customer perspective of Oracle has also been changing over the past several years. A June 5th Wall Street Journal article cites a survey taken by Wellesley, Mass research firm Nucleus Research which found that when 56 executives (29 of which were SAP customers and 27 of which were Oracle) were asked whether the customer got a “positive return on investment”, 93% of the Oracle customers said ‘yes’ compared to only 41% of the SAP customers.Oracle trumped SAP in all categories:Project completed on timeProject completed on budgetCustomer would recommend the software to peersSAP disputed the results saying that interviewing only 29 of their 26,000 customers wasn’t sufficiently large to draw any conclusions from. The SAP spokesperson called the study “junk science”.But one thing is clear, Oracle is aggressively attacking SAP on all fronts, and since March, the attack now also includes the courts. On March 22 Oracle sued SAP saying that SAP had broken into Oracle’s website and illegally downloaded Oracle software. Oracle is suing for copyright infringement and breach of contract.Oracle’s suit also alleges that the SAP division called TomorrowNow took Oracle-copyrighted material and supplied it to SAP customers. Oracle is charging that TomorrowNow engaged in a “deliberate, systematic and illegal scheme to acess, copy, use and distribute Oracle’s copyrighted software products and related materials” in violation of federal and state law.Meanwhile rumors are flying that Oracle is acquiring SAP stock with the intent of acquiring it. That’s unlikely though since today Oracle’s capitalization is around $100 billion while SAP’s market capitalization is about $59 billion. Anyone attempting to buy SAP would need to pay a premium that might bring the pricetag up to nearly $70 billion, more than two-thirds Oracle’s capitalization. Oracle would find it difficult to control the merged entity.Where this will all lead is anyone’s guess. But it is very likely that the headlines surrounding the Oracle-SAP rivalry aren’t going to go away any time soon.
