Oracles $3.3 billion bid to acquire Hyperion Solutions is the latest in a wave of developments happening in the business intelligence (BI) market. Earlier deals included NCRs plan to spin off its data warehousing unit, Teradata, as an independent company, and Hewlett-Packards announcement that it has been silently working on a data warehousing platform. BI vendors have been adding to its product portfolio and bolstering their customer base by acquiring each other. The BI market is huge and is continuing to grow, which has prompted the wave of mergers and acquisitions over the past few years. The Oracle-Hyperion deal is considered a blockbuster in a market where the usual deals involve small, specialized companies. Hyperion caters to a niche market, which comprises financial planning and management software, but it is a lucrative market because Hyperions applications are the system of record for financial reporting and regulatory filings for majority of Fortune 500 companies. The Hyperion acquisition makes Oracles BI portfolio stronger, which it can leverage to effectively compete against enterprise application rival SAP. In addition, the deal will enable Oracle to tap into all five segments of BI, which include foundation services, BI dashboards and reporting tools, databases and other data stores, analytical applications, and transactional applications. With numerous developments happening in the BI market, the battle among vendors has only begun.
