Task
Most client apps we build need the same backend: a database, a REST API, live updates and access control. Writing it again for every project costs time and leaves one more service to run. Sistemium API turns that backend into a service: the data model is described in a portal, and the API follows it.
Solution
- Entity designer with fields, types, relations and indexes
- Scoped access tokens per account and domain
- Generic REST API with filters, batch writes and bulk reads
- WebSocket subscriptions to any filter: clients learn which records enter or leave it
- Deleted records are archived, so clients that worked offline can catch up
- A separate database for every account
