IBM® InfoSphere® Data Explorer is software that provides federated discovery, navigation, and search over a broad range of data sources and types, both inside and outside your enterprise, to help users of all kinds find and share information more easily and to help organizations launch big data initiatives more quickly. In addition to the core indexing, discovery, navigation and search engine the software includes a framework for developing information-rich applications that deliver a comprehensive, cont
In the big data context, the latest generation of Data Explorer Engine is most commonly used to develop data exploration and information navigation applications that enable you to explore vast quantities of your enterprise data, regardless of where it is stored, providing fast time to value. Its navigation and exploration capability makes it easy to use Data Explorer Engine as a stepping stone for and core component of enterprise big data projects.
Data Explorer architecture
Data Explorer Engine provides a flexible, modular architecture that enables it to interact with the widest possible number of networked data repositories and with other network-accessible data sources such as search engines. This architecture simplifies creating single information navigation applications that can simultaneously explore content stored in a variety of formats and locations. This includes formats that are unique to specific applications and their associated data repositories, and the combination of different data formats that are found in networked repositories where heterogeneous content is to be expected, such as file systems or content management systems.
Exploring data repositories through Data Explorer Engine leverages the same basic capability that is used to search them, which is an index of the contents of all of the documents in that repository. Data Explorer Engine creates an index of the documents from a single data repository by:
The figure below shows the functional components of Data Explorer Engine, the interaction between them and external data repositories (identified as DATA in the figure), and their use in a typical information navigation or search application.
Data Explorer Engine administration tool
The Data Explorer Engine administration tool is a graphical, browser-based tool that is used to configure, manage, and debug the data exploration and information navigation applications that you create with Data Explorer Engine. This tool provides a graphical interface that enables you to configure the Data Explorer Engine software without having to modify the XML configuration information that Data Explorer Engine uses internally, and also provides a convenient interface for viewing the online documentation that is provided for Data Explorer Engine and the administration tool.
Application Builder architecture
Data Explorer Application Builder is a framework for developing 360-degree information applications that extend the capabilities of Data Explorer Engine by enabling users to quickly locate and use information that is specific to their role, interests, and capabilities within an organization. Application Builder adds a data relationship definition layer that supports logical data items known as “entities” which are associated with specific data sources or user data. Entity definitions make it easy to specify relationships between data in different repositories by identifying related or equivalent data fields in each repository - these are conceptually analogous to the key fields used in traditional applications such as databases.
The figure below provides a high-level view of how Application Builder leverages Data Explorer Engine, centralized enterprise services such as Active Directory or LDAP, and its own relationship mapping and definition capabilities to provide authenticated users with up-to-date, role-relevant information that respects existing authorization and data permissions.
