Documentum xPlore
New EMC Documentum xPlore to Replace FAST Instream SearchxPlore Architecure
xPlore and the Legacy FAST Instream can be compared in terms of their architecture. Some points of comparison include:
[*]xPlore's architecture is more elegant and simple than FASTs : xPlore has fewer processes and a single unified XML database. Complexity and large process footprint can lead to resource bloat and reliability problems.
[*]xPlore Leverages best-of-breed technology: xPlore leverages best-of-breed technology for all of its components (xDB XML database, Lucene for base full text indexing, and industry leading linguistic analysis and content extraction technology).
[*]xPlore uses Standard Query languages instead of proprietary ones: xPlore uses xQuery instead of the proprietary FAST query language (FQL).
