COMPARATIVE STUDY INTO ARCHAIC SOFTWARE INTEGRATION BASED ON NATO S4 SOFTWARE LIBRARY

Abstract

This study aims to research different integration strategies for a legacy
software suite, focusing on comparing Command Line Interface (CLI) and web API
methods. The research evaluates these approaches using both objective metrics,
such as CPU/RAM usage and response times, and subjective metrics, including client
satisfaction. Results showed that CLI integration handles a higher volume of lowcomputation-
time requests more efficiently, while RAM usage was similar across all
requests and integrations. Response times were marginally longer for the web API
integration, but the differences became less significant for more complex requests.
Feedback from the client indicated a lack of strong preference, however the importance
of efficient CPU and RAM usage was emphasised due to the crucial need for
battery efficiency. Although the integrations in this study exhibited minimal differences,
these findings will provide valuable insight for future integration projects
and suggest possible avenues for further research in this domain.
