Business Entities and Systems - TDM DB Tables
TDM settings are saved in the TDM PostgreSQL DB.
Business Entity (BE) and System definitions update the following TDM DB tables:
Business_Entities
This table holds all BEs defined in the TDM Portal.
A new record is created for each BE.
Each BE is created in Active status and gets a unique be_id sequence, which is the table's PK.
Deleted BEs have an Inactive status and are not physically deleted from this table.
Note that to prevent creating several active BEs with the same name, the be_name column has a unique index when the status is Active.
Products
This table holds all systems (products) defined in the TDM Portal.
- A new record is created for each system.
- Each system (product) is created in Active status and gets a unique product_id sequence which is the table's PK.
- Deleted systems have an Inactive status and are not physically deleted from this table.
Note that to prevent creating several active systems with the same name, the product_name column has a unique index when the status is Active.
Product_Logical_Units
This table holds the links between a BE, LU and a system (product), as follows:
- Links between LUs and a BE.
- Links between parent-child LU relationships in a BE.
- Links between a BE and its LUs to a system (product). Each BE and LU combination can be attached to a system.
Adding an LU to a BE creates a new record in this table. Each record is marked with a unique lu_id sequence which is the table's PK. The table contains the following information:
- LU information - lu_id, lu_name, lu_description and lu_dc_name columns.
- BE information - be_id column. This is the link to the business_entities table.
- LU relationship in the BE - lu_parent_id and lu_parent_name columns holding the ID and name of the parent LU if it exists.
- System (product) information - product_id and product_name columns. The product_id links to the Products table. The product_id and product_name columns are set to -1 and NULL default values when the record is created. System Information settings are defined when an LU is attached to a system. If the LU is deleted from a system, the system information's columns return to their default values.
TDM_BE_Post_Exe_Process
This table holds a list of Post-Execution Processes attached to each BE. A separate record is created for each post-execution process. Each record is marked with a unique process_id sequence which is the table's PK.
The following information is stored in this table:
Process Information - process_id, process_name, process_description and execution_order columns.
BE information - be_id column that links to the business_entities table.
