Data Selection, Sharing, and Access Control in a Relational Scenario

Fully fledged database systems have operational characteristics not commonly provided by programming language systems. Examples of this would be access and integrity control, failure recovery, data sharing, and concurrency management.This chapter discusses the way in which programming language constructs (such as data structures and their selection mechanisms, scope rules, procedures, modules, and variable import and passing mechanisms) can be utilized to support the above operational characteristics in the context of an integrated database programming environment.
