CODE functionality that has been added. 1. Code Objective

CODEREVIEW The pointof the code review is to check the code that has been developed for a systemfor faults, strengths and weaknesses. This helps to develop ways to optimizethe code for better performance and helps improve documentation for higher codequality. This delivers an error-free/ bug -free application that meets the requirementsof the customer/ end -user. The following points describes the standard thatcode should be designed and should be used as a checklist for any functionalitythat has been added.1.      CodeObjectiveThe code for functionality X achievesits purpose for what it’s designed for. It should follow the following theobjectives below to ensure correct architecture and should follow the set codestandard and quality. See code standard and quality.

2.      Code doesn’tbreakValidations are used wherevernecessary. The code never breaks under any circumstances. Especially underinvalid inputs that come from the end user. Examples of the inputs couldbe that they’re negative, over-sized or have an invalid format etc.

Every inputpassed should be sanitized before its processed, to prevent code breaking.Every object is checked for its actual data existence before accessing itsproperties.3.      Architectureis constant throughout Check that the approvedarchitecture/design is followed throughout the application. If there are anydesign changes required, make sure that these designs are documented, testedand approved before implementing them in the existing code.4.

      Error responsesfor bad inputs Not just the error messages, everyresponse that is returned by the server must be handled appropriately. Itshould have response messages, error codes and any other necessary details attachedso responses are as useful and meaningful as possible to the end – user. All responsesshould be as consistent as possible. All possible scenarios are tested to avoiddeadlocks, timeouts, etc.5.      TestedEvery highly dependant method has aunit test which passes.

6.      Reusable/NorepetitionAll methods serve a limited and clearpurpose follows the methodology of the DRY principle. Functions are reused whereverpossible.  Any implementation of thesefunctions should be written in such a way that they can be re-used in thefuture implementations. There is no duplication of code.

7.      Code hasadequate/good performanceThere are no significant delaysbetween the requests and responses. The code is scalable and able to handle alarge amount of data and any upcoming features of added new functionalities. 8.

       Code is secureThe code is secure and will prevent unauthorizedaccess, directory browsing, SQL injection etc. This is important so sensitive personaldata isn’t leaked.
