The convergence of low-code platforms with cloud services represents a paradigm shift in enterprise application development, enabling rapid, scalable solutions for unstructured data management and dynamic document creation. This paper proposes a low-code architectural framework integrating Oracle Application Express (APEX) with Oracle Cloud Infrastructure (OCI) Object Storage for durable file handling and OCI Document Generation for serverless template-based output. Rooted in APEX's metadata-driven database architecture, the framework utilizes PL/SQL packages like DBMS_CLOUD for storage operations and APEX_WEB_SERVICE for RESTful calls to OCI APIs, ensuring seamless data flow and minimal custom coding. The methodology outlines declarative integration patterns, emphasizing security through OCI Identity and Access Management (IAM) and performance optimization via serverless execution. Discussions evaluate architectural synergies, including cost reduction and scalability, while business cases demonstrate applications in invoice automation and legal workflows. Future trends highlight AI-assisted enhancements for no-code evolution. This work contributes a practical blueprint for organizations seeking efficient, compliant integrations, to address gaps in low-code cloud synergies.
