SAN CARLOS, CA — October 8, 2007 — MarkLogic Corporation, a leading provider of infrastructure software for information applications, today announced that ENSCO Inc., a diversified research, development and information technology company based in Falls Church Va., has entered into an OEM partnership with MarkLogic. With this agreement, ENSCO has licensed and embedded MarkLogic Server OEM Edition as a core component of its new Healthcare Intelligence Platform.

ENSCO's data management practice—ENDATA—develops solutions to enable customers in the healthcare, national security, and online media industries to gather and leverage the massive amounts of unstructured content within their organizations. The ENDATA Healthcare Intelligence Platform consolidates patient information and extracts key clinical terminology from any number of data and content sources � both structured and unstructured � to support several applications which directly impact a hospital's quality of patient care and revenue cycle. Its Coder's Workbench� modules ensure hospitals will be able to address upcoming severity-of-illness reimbursement changes by using its clinical extraction engine to find all pertinent diagnoses and procedures to make coders more efficient and accurate. ENDATA's Clinical Studies module allows quality managers and researchers to query patient documentation directly in support of patient safety, outcomes and risk management initiatives.

Organizations use MarkLogic Server to unlock the value of their content, improving how they integrate, enrich, and contextualize it to deliver new products and services. Based on its ability to reliably handle extremely large volumes of both structured and unstructured content, and its highly scalable and expressive query capabilities, MarkLogic Server OEM Edition enables partners to build sophisticated applications to gain competitive advantage.

The ENDATA healthcare intelligence solution built on MarkLogic Server uses advanced text mining technologies to identify, extract, and consolidate all clinical information with patient documentation and data sources. This clinical information becomes the source for inpatient and outpatient coding, clinical studies, and bio-surveillance applications. It saves healthcare professionals from having to wade through volumes of information to find relevant clinical content to help them perform their jobs more efficiently. It also enhances a hospital's ability to meet compliance requirements and regulatory audits.

“Virtually every enterprise application today deals with some form of high-value content, from office documents, email, reports, contracts, or electronic forms,” said Bill Veiga, vice president of business development at MarkLogic Corporation. “Application vendors realize that integrating a relational database and traditional search systems to build applications for unstructured content results in solutions that are often inflexible and difficult to maintain. MarkLogic OEM Edition solves this problem by providing a robust platform for building powerful content applications and we are pleased that ENSCO has chosen MarkLogic to power their new health care intelligence applications.”

“We quickly leveraged many of the advanced capabilities of MarkLogic Server to develop our highly differentiated application in a very efficient and effective manner,” said Scott Lee, Director of ENSCO's data management practice. “By incorporating MarkLogic Server OEM Edition into our healthcare intelligence solutions, we not only improve the speed and accuracy of accessing critical patient information, we provide the user community an entirely new way of working with clinical content. It's a fundamental shift that is resonating strongly among healthcare professionals”.
