You are here: Reference Data Library

System-level Reference Data Library

The following sets of System-level Reference Data are provided with OEDQ.

Note: Reference Data lists and maps that are shipped with OEDQ are named with an asterisk before their name to differentiate them from Reference Data that you create.

Many of these lists and maps are used by processors by default. You may change these (by using them in projects, modifying them, and copying them back to the System library), though it is advisable to create new lists and maps with different names for your own needs, so that they will not be overwritten when OEDQ is upgraded.

Oracle also provides packs of Reference Data for specific types of data, and for solving specific problems - for example, lists of known telephone number prefixes, name and address lists, and regular expressions for checking structured data such as URLs. These packs are available as extension packs for OEDQ. Please contact your account representative for more information on purchasing extension packs.
