Terminology

The following terminologies are used in the IIR product:

Batch Search Client - DupFinder: Refers to the rule based search client provided with IIR to run duplicate searches within an IDT. Output is to a file or database table.

Batch Search Client - Relate: Refers to the rule-based batch C search client provided with IIR to run searches against the IIR Identity Indexes via the Search Server. Input is from a file or database tables. Output is written to a file or database table.
IIR Console: The IIR Console is used to administer the operational aspects of IIR, including System Loading, Table Loading, and the startup and shutdown of the servers. The IIR Console is comprised of the Console Server and Console Client.
IIR Identity Table (IDT): An IIR Identity Table (IDT ) is a table stored in the user’s database containing denormalized and transformed matching and display data extracted by IIR from the User Source Table(s). The IDT is accessible using native SQL.

IIR Identity Index (IDX): An IIR Identity Index (IDX ) is a table stored in the user’s database containing key information plus compressed matching and display data. Each IDX maps to a physical index (IDXi). This is also known as a heavy index.

IIR Identity Link (IDL): An IIR Identity Link (IDL ) is an IIR table stored in the user’s database containing relationships (links) between rows of the IDT.
IIR Nucleus: The IIR Nucleus is a term used to describe the collection of servers that provide the indexing, search and matching facilities of IIR.
IIR Search Server: The IIR Search Server provides multi-user local and remote access to IDT & IDX tables.
IIR Tables: Refers to all of the database tables and indexes created, used and maintained by IIR.
Lite Index: A Lite Index is a non-fuzzy index on an IIR Identity Table column. It has lower storage requirements than a heavy index but requires additional I/O when used in a search.
Online Search Client: Refers to the rule-based Java search client provided with IIR to run searches against the IIR Identity Indexes via the IIR Search Server. Input and output is to a screen.
Population file: Contains the SSA-NAME3 Key-building Algorithms, Search Strategies and Matching Schemes used by IIR.
Rulebase: The IIR Rulebase contains all of the information and rules necessary to run an IIR System. It is stored in tables on the user’s database. It is accessed via the IIR Rulebase Server and is maintained by the Rulebase Client.

Source Database: The source database is the database containing the User Source Tables.

System: A system is the highest level logical definition in an IIR Rulebase. It can be thought of as corresponding to the user’s view of a system, although this is not enforced. Many systems can be defined to the Rulebase.

System Definition File (SDF): The SDF is a text file containing the rules for a System. It is loaded to the Rulebase via the System Loader.
System Loader: The System Loader is a set of utilities used to load an IIR System to the Rulebase. It is normally run from the IIR Console.
Table Loader: The Table Loader is a set of utilities used to extract, denormalize, transform and key data into the IIR Identity and Index Tables. It is normally run from the IIR Console.
Target Database: The target database is the database containing the IIR Tables and Indexes

Update Synchronizer: The Update Synchronizer is a program that actively monitors changes to the User Source Tables and synchronizes these changes to the IIR Identity Tables and Indexes.
User Service Group (USG): Contains the SSA-NAME3 v1 Key-building Algorithms, Search Strategies and Matching Schemes used by IIR.
User Source Table (UST): A User Source Table (UST ) refers to user data stored in a table in the user’s database containing the identity data to be searched and matched.
