| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Computers (Mainframe/Early) (computers_early) | required | 88% | primary_source | Operational hospital information systems require electronic computing infrastructure; HELP was implemented on a Tandem computer system with CPUs, disk storage, and communication ports. |
|
| Database Management Systems (database_management_systems) | enabling | 76% | primary_source | HELP used a database-management subsystem, so HIS depends on general database-management capability rather than specifically relational DBMS. |
|
| Software Engineering (software_engineering) | enabling | 72% | primary_source | HELP's application programs were organized around database, decision-making, manual-entry, and communications subsystems, making systematic software development an enabling foundation. |
