Data migration is necessary when upgrading app versions, changing database schemas, or moving data between storage systems. Migration techniques include incremental updates, export/import routines, and transformation scripts. Developers write migration code to convert old data formats into new structures without data loss. Testing migrations thoroughly prevents runtime errors and data corruption. Some mobile databases offer tools and APIs to simplify migration processes. Smooth data migration ensures seamless app updates and maintains data integrity across versions.
Mobile Database Support for Multi-Tenancy
Multi-tenancy allows a single mobile database instance to securely mobile database support multiple users or organizations by isolating their data. Techniques include using separate schemas, row-level security, or encrypted partitions per tenant. This is useful in apps serving multiple clients or users on shared devices. Proper isolation prevents data leaks and maintains privacy. Multi-tenancy reduces resource usage by sharing infrastructure while offering customized data views. Some mobile databases provide built-in multi-tenancy support to ease development of SaaS and enterprise apps.
