DB2 Basics: How to get useful information from the DB2 UDB system catalog
DB2 UDB maintains a set of special tables called the system catalog. These tables, which contain the metadata that describes database objects, have two sets of views defined on them: read-only views under the SYSCAT schema and updatable views under the SYSSTAT schema. This article introduces the DB2 UDB system catalog, and shows how this rich repository of database information can be mined for useful information. Examples of how to query the catalog (using either the command line or the DB2 Control Center) are provided.

XML full-text search in DB2
With the support of natively storing XML documents, IBM DB2 9 takes an evolutionary step towards a hybrid database system. XQuery, a new primary language in DB2, allows for optimally working with XML. However, XML also often contains large portions of text that are not easily searchable with XQuery. To efficiently search these unstructured parts of the documents, DB2 provides a full-text search solution. This article focuses on the basics of DB2 text search, including text index creation and administration. This article also explores specific features of DB2 full-text search, such as searching for keywords or phrases in the XML document structure with fuzzy search, proximity search, and stemming.
