Description

NOCTI Computer Programming (Latest 2023 – 2024) Complete Solution User requirements - specifies what the user expects the software to be able to do. This is the source document. The input screen design should follow the same order. Design document - lays out the general requirements that when changed, motivate the existence and purpose of a given code set. Functional requirements - will specify a behavior or function. Business Rules, Transaction corrections, adjustments and cancellations, Administrative functions, Authentication, Authorization levels, Audit Tracking, External Interfaces, Certification Requirements, Reporting Requirements, Historical Data, Legal or Regulatory Requirements Non functional requirements - Quality characteristics or quality attributes. Other definition parts - specify how the system should behave. The operation of a system. Constraint on system behavior. Performance - for example Response Time, Throughput, Utilization, Static Volumetric, Scalability, Capacity, Availability, Reliability, Recoverability, Maintainability, Serviceability, Security, Regulatory, Manageability, Environmental, Data Integrity, Usability, Interoperability Input format - how to interpret the contents of an input field as a number or a string. Output format - print and write formats. Automatically generated from the input formats. Oval - terminator. start/end Parallelogram - input/output Rectangle - process. Either single step or an entire sub-process. Diamond - decision. Circle - connectors. Requirements specifications - establishes the basis for agreement between customs, contractors, or suppliers on what the software product is to do as well as what it is not expected to do. Software design - involves planning a software solution in a sequence of steps that enables the designer to describe all aspects of the software to be built.
