Architectural Decisions

Key technical decisions that shaped platforms

Problem

Monolithic database was becoming a bottleneck for 30+ applications with independent release cycles and scaling needs

Decision

Implement decentralized database architecture where each application maintains its own database, with ContentProviders for cross-app data sharing

Rationale

Enables independent module scaling, reduces coupling, allows apps to evolve independently, and improves overall system resilience

My Ownership 100%

Impact

Adopted as standard pattern across all 30+ E70 applications, enabling independent release cycles and horizontal scaling
