Footprints Data Model

Table
Name audit_txn
Comment A record of the Principal and create time of the start of the commit time of a logical transaction. In many cases multiple Audit Log entries will use the same transaction.

Column
Name Datatype Comment Is PK Is FK
audit_txn_id bigint The automatically generated primary key of the audit_txn table. Yes No
txn_start_date datetime The transaction date of the Audit Log entry. This date may not be in strict order with the Audit Log id in the event that features are used to continue a previous Audit Log transaction. No No
app_user_id bigint A Foreign Key to the Application User table. The audit trail transaction may or may not be associated with a customer or agent user. If this column is null, then a system component should be identified. No Yes
sys_component_id int This is a foreign key to the system component table. The audit trail transaction may or may not be associated with a customer or agent user. The system component will be set if there is no application user identified. It identifies the source of the transaction. Values include SYSTEM, WEB_SERVICES, ASSET_MANAGEMENT, CALENDAR, IMPORTING, etc. All identifiers are negative, so that they can be distinguished from userids in case they are both stored in the same dynamic table CreatedBy, and UpdatedBy fields. We are going to try first normal form normalization here and see if it works. No Yes
