Overview

The IGS_IN_APPL_CHAR_TYP table is a data object within the Oracle E-Business Suite (EBS) Student System (IGS) module. Its primary function is to store the association between a person's enquiry or application and specific characteristic types that describe that enquiry. As explicitly noted in the official documentation, this table is flagged as 'Obsolete'. This status indicates that while the table may still exist in the database for historical data integrity or upgrade compatibility, its use in new implementations or ongoing processes is deprecated. The table's role was to act as a junction entity, linking an applicant's enquiry record to a defined set of enquiry characteristics within the system's data model.

Key Information Stored

The table's structure is defined by a composite primary key, which uniquely identifies each record. The key columns are PERSON_ID, ENQUIRY_APPL_NUMBER, and ENQUIRY_CHARACTERISTIC_TYPE. PERSON_ID links to the individual who made the enquiry, while ENQUIRY_APPL_NUMBER identifies the specific enquiry or application instance for that person. The ENQUIRY_CHARACTERISTIC_TYPE column stores a code that categorizes the type of characteristic associated with the enquiry, such as the source of the enquiry, the program of interest, or other classifying attributes. This column is also the focal point for referential integrity, enforcing that the characteristic type code exists in the related code table.

Common Use Cases and Queries

Given its obsolete status, direct operational use cases for this table in active development are minimal. Its primary contemporary use is for historical data analysis, data migration validation, or troubleshooting legacy data issues. A common query pattern involves joining this table to the person and enquiry master tables to retrieve a historical profile of enquiry characteristics for an applicant. For example, a report to list all characteristic types associated with a specific application would use the primary key columns in its WHERE clause. Analysts might also run queries to identify orphaned records where the ENQUIRY_CHARACTERISTIC_TYPE no longer exists in the reference code table, which is crucial for data cleansing exercises during system upgrades or consolidation.

Related Objects

The table maintains defined relationships with other objects in the IGS schema, primarily through its primary key and foreign key constraints.

• Primary Key: IGS_IN_APPL_CHAR_TYP_PK on columns (PERSON_ID, ENQUIRY_APPL_NUMBER, ENQUIRY_CHARACTERISTIC_TYPE). This is the object referenced in the user's search.
• Foreign Key (References): The ENQUIRY_CHARACTERISTIC_TYPE column references the IGS_IN_ENQ_CHAR_TYPE table. This relationship ensures that any characteristic type assigned to an application is a valid, predefined type within the system.
• Foreign Key (Referenced By): The documentation indicates a recursive or circular foreign key relationship where IGS_IN_APPL_CHAR_TYP.ENQUIRY_CHARACTERISTIC_TYPE also references a percentage symbol (%), which typically denotes a reference to itself or an unspecified parent table in the source metadata. This requires careful interpretation but suggests potential hierarchical data within characteristic types.

As a junction table, IGS_IN_APPL_CHAR_TYP is logically positioned between core application/person tables (like IGS_PE_PERSON) and the code table for enquiry characteristics (IGS_IN_ENQ_CHAR_TYPE).
