SAP DB E-Catalog is a
database instance type of the SAP DB database system.In Internet catalog applications, a small number of hits must be determined from a large number of product descriptions. To support this, the TREX search engine has been integrated in the
SAP DB OLTP relational database system. With the TREX search engine, product descriptions (long texts) can be indexed, and the search terms looked for (exact search, phrase search, fuzzy search, linguistic search).One application example is the BugsEye or eMerge product from Requisite.
