CA VISION:Sixty

The architecture of CA VISION:Sixty consists of several key components: the compiler, the runtime environment, data access modules, and the report formatting engine. The compiler translates CA VISION:Sixty source code into executable instructions. The runtime environment provides the execution environment for the compiled code.

Data access modules handle interactions with various data sources, including VSAM, ISAM, and other mainframe databases. The report formatting engine is responsible for generating the output reports based on the program's specifications. Data access is achieved through file definitions and database connections defined within the CA VISION:Sixty program.

For example, a program might use SELECT to read data from a VSAM file, COMPUTE to perform calculations, and PRINT to format the output. The system relies on the mainframe's operating system for resource management and security. Compared to modern architectures, CA VISION:Sixty's design is optimized for mainframe environments, providing efficient data access and report generation capabilities for legacy systems.

The primary communication method between components is through the mainframe's internal mechanisms.
