What accurately describes validation chaining? It is the practice of creating chains of validation class instances to validate each type of object in the policy graph and then iterating over the chains, invoking the appropriate validation method.   It is the creation of chains of Business Rules, for efficiency, which can be applied to verify that every type of object in the policy graph is correct.   It is the creation of validation class instances, each of which validates objects at one level in the policy graph and which may in turn create validation class instances to validate objects at a lower level.   It is the automatic validation of each type of object in the policy graph, by inferring the correct type of validation from information in the product model and entity definitions.

Requirement Analysis

A process that determines the user expectations for a software product is called requirement analysis. In software engineering, requirement analysis is known as requirement engineering. It involves communication with end-users and stakeholders to determine whether the system or software requirements are validated, conflicts are solved, and key requirements are documented. The first activity of the Software Development Life Cycle (SDLC) is requirement analysis.
