Group: access to data

Summary

Actions are performed on objects. For an action to occur, these objects must be accessed. In fact a large proportion of computer activity is either accessing memory or computing access functions. Access must always specify a component's environment either explicitly (e.g., component 'b' as A.B), implicitly (e.g., the variable I in some local environment), or by context such as access by current position or access by pattern. The environment may be a local context, a global context, another task or process, or a data object. (cbb 5/80)
