This paper informs about design and implementation of error handling facilities in business information systems. It presents a pattern language for the object oriented design of components needed for error handling and also present sample code in different programming languages (C++ Java Cobol Smalltalk).
Error Handling in the FRD:::: In the design details there will be a ERROR HANDLING section where it will be mentioned about the error that will be present in the routine /script/code so that by seeing error messages which be taken care and corrected.
Even while testing also.
And also ERROR HANDLING is when a routine is run for certain specification then if the specification is not present then a error will be added through a remark by the routine itself when these remark is seen so that the specification is corrected as per the requriement
