complex and varied data from disparate sources. At the core of Endeca Information Discovery, the unique NoSQL-like data model and in- memory architecture of the Endeca Server create an extremely agile framework for handling complex data combinations, eliminating the need for complex up-front modeling and offering extreme performance at scale. Endeca Server also supports 35 distinct languages. About this guide This guide describes the administrative tasks for the Oracle Endeca Server application running in a WebLogic Server. Who should use this guide This guide is intended for system administrators who administer and maintain an Oracle Endeca Server application and the data domains running in it. This guide assumes that the Oracle Endeca Server software is already installed on a development server. It may be already installed in a production environment. It also assumes that you, or your Oracle Services representatives, have already configured the application on the development server. You can choose to read specific topics from this guide individually as needed while maintaining your Oracle Endeca Server implementation after it has been initially deployed.
