APSII stands for Application Programming Standard II, which is a specific standard or specification used in the field of computer programming. It is primarily used in the context of mainframe or legacy systems, which typically employ a hierarchical database structure. APSII provides a standardized set of rules and guidelines for developing and maintaining applications that interact with these systems.
The main purpose of APSII is to facilitate the integration of various software applications with a mainframe or hierarchical database, ensuring interoperability and compatibility. It defines a set of conventions and protocols that govern how programs communicate with the database, query and retrieve data, and perform various other operations.
APSII encompasses areas related to data manipulation, data retrieval, and data organization within a hierarchical database. It specifies the format and structure of data records, including field lengths, data types, and data organization rules. Additionally, APSII defines the syntax and structure of programming commands and statements used to interact with the database.
In summary, APSII is a programming standard used to ensure consistency and compatibility when developing applications for mainframe or hierarchical databases. It provides guidelines for defining data structures, accessing and manipulating data, and communicating with the database system. Following the APSII standard helps developers create reliable, interoperable, and maintainable software solutions for these specific types of systems.
