Product Overview

Supra PDM is a hierarchical database management system designed to provide a structured approach to data storage and retrieval. It is particularly suited for organizations with established systems built around hierarchical data models. The architecture of Supra PDM comprises several key components: 1.

**Database Engine:** The core component responsible for managing the hierarchical data structure, handling data storage, and executing queries. 2. **Utility Command Language (UCL) Processor:** Interprets and executes UCL commands for database administration and maintenance tasks.

3. **Relational Data Management Language (RDML) Pre-compilers:** Translate RDML code into executable code for application access. Pre-compilers are available for COBOL and PL/1.

4. **SQL Interface:** Provides SQL access to the database, allowing for standard SQL queries and data manipulation. 5.

**VSAM Interface:** Enables access to VSAM files, facilitating integration with existing VSAM data. These components communicate through internal APIs and protocols. The database engine uses a proprietary storage mechanism for the hierarchical data.

Network requirements depend on the specific configuration and client access methods used. Alternatives to Supra PDM include relational database systems like Db2, but Supra PDM maintains value when existing systems are heavily invested in a hierarchical approach.
