In view of the backward technical architecture of traditional scientific research data management system, crisscross chimney application and repeated construction of business modules, a scientific research data management middle platform based on LCAP low-code application development platform is proposed by referring to the landing experience of Internet business middle platform and the characteristics of scientific research data management business. Based on the idea of “common service sinking, capability service output”, the middle platform builds common basic services, LCAP core services, generic scientific research data services and integrated external services, and provides shared, efficient, standard and standardized common services for the upper-level scientific research data management business applications. Through research and analysis, it is one of the effective ways to change the current situation of traditional scientific research data management system to adopt the idea of combining LCAP and middle and traditional scientific research data management system.
