Platform Unit of Measure
| IT Resource Sub Tower | Unit of Measure (standard) | Guidelines |
|---|---|---|
| Database | Database Instances | A database instance is a logical database hosted within a DBMS installation. Note: Some cases a DBMS may host several database instances. System tables and other master data are not counted and only data provided to end-users and end-user applications are counted (including development and test dbs). |
| Mainframe Database | Databases | A mainframe database is a database sub-process (provision of database management systems (DBMS) such as DB2 and Oracle on Mainframe platforms). |

Middleware Mainframe Middleware |
Middleware Instances | Number of instances of middleware package. |
