System Interface Specifications & Data Mapping
Interface specifications define how separate IT systems exchange data seamlessly. Technical BAs demonstrate capability by building source-to-target data mapping documents, defining field transformation rules, specifying API payloads, and documenting error handling.
1. Source-to-Target Data Mapping Specification
Comprehensive mapping spreadsheet detailing source fields, target schema attributes, data types, and transformation rules.
2. System Integration Interface Specification
Technical integration document specifying API endpoints, JSON/XML request-response structures, and header standards.
3. API Field Transformation & Error Log
Specification mapping field conversion logic (e.g. string formatting, date conversions) and exception handling rules.
Frequently Asked Questions (Interface Specifications & API Mapping)
What is a Source-to-Target Data Mapping document?
A specification that maps individual data fields from a source system table/API to their corresponding destination fields in a target system, defining necessary data type conversions.
How do you handle data type mismatches during integration mapping?
Define explicit transformation rules (e.g. cast string '123' to integer 123, reformat date 'DD/MM/YYYY' to ISO 8601 'YYYY-MM-DD').
Why are error response mappings necessary in interface specifications?
They define how integration middleware handles system timeouts, invalid payloads, or target server errors gracefully without dropping messages.
