Data federationCAPData federationReading data that lives in another system as if it were local — by federating the query, by copying the rows, or by caching what was read. Three different answers to one question, and the choice is about how stale you can afford to be.Database connectorsCAPDatabase connectorsConnecting an application’s data model and queries to a database, including the differences in supported queries, types and schema management between database implementations. Changing an existing schema belongs to [schema evolution](capability:schema-evolution).DestinationsCAPDestinationsReaching a system that is not yours — an S/4HANA tenant, an on-premise service, a third-party API — without the address, the credentials or the tunnel being written into the application. The destination is the indirection, and the reason an endpoint can move without a redeploy.Metadata publishingCAPMetadata publishingDescribing a service to something other than a human — service metadata for clients, and machine-readable descriptions for registries and discovery.Native SAP HANA artifactsCAPNative SAP HANA artifactsUsing native SAP HANA database objects alongside an application’s generated data model, including objects and database features the modelling layer cannot express. Choosing a database is [database connectors](capability:database-connectors); changing an existing schema is [schema evolution](capability:schema-evolution).Service integrationCAPService integrationUsing a service that runs somewhere else as if it were one of your own: its API imported into the model, a proxy that turns a local query into the remote protocol, and a mock that stands in for it on a laptop. Distinct from [destinations](capability:destinations), which is how the address and the credentials are found, and from [replication](capability:replication), which is holding the data locally.

@cap-js/cds-dbs@cap-js/cds-dbsThe monorepo behind CAP's SQL database services — the base service, SQLite, PostgreSQL and HANA all live here, which is why they version together.sap official, cap
Monorepo of CAP's SQL database services
@cap-js/db-service@cap-js/db-serviceThe base every CAP database service is built on: the shared query translation and pooling that SQLite, PostgreSQL and HANA specialise rather than reimplement.sap official, cap
Base service shared by CAP's SQLite, PostgreSQL and HANA services
@cap-js/hana@cap-js/hanaThe HANA database service — the production default, on the same streamlined architecture as the SQLite and PostgreSQL services.sap official, cap
SAP HANA database service for CAP
@cap-js/ord@cap-js/ordGenerates Open Resource Discovery documents from a CAP model.sap official, cap
Generates Open Resource Discovery documents from a CAP model
@cap-js/postgres@cap-js/postgresThe PostgreSQL database service — the production option for running CAP off HANA, sharing the base service with the other three.sap official, cap
PostgreSQL database service for CAP
@cap-js/sqlite@cap-js/sqliteThe SQLite service, in memory during the inner loop — which is why a CAP project runs before anyone has provisioned a database.sap official, cap
SQLite database service for CAP, in memory during development
capire/docscapire/docsThe sources of capire itself, in the repository it is built from: the documentation every core_coverage claim in this graph is checked against, so a claim can be dated against a commit.sap official, cap
Sources of capire, the CAP documentation
capire/s4capire/s4A pre-built integration package for SAP S/4HANA, holding the imported service definitions a CAP project would otherwise generate for itself.sap official, cap
Prebuilt SAP S/4HANA integration package for CAP projects
cds-federation-synonymscds-federation-synonymsAn experimental CAP plugin for CAP-to-CAP data federation over SAP HANA synonyms, so one project reads another's tables without the rows being copied.sap official, cap
When your adoption policy excludes experimental dependencies: the [maintainer’s README](https://github.com/cap-js/cds-federation-synonyms#about-this-project) explicitly labels this plugin experimental.

SAP-samples/fiori-elements-v4-cap-advancedSAP-samples/fiori-elements-v4-cap-advancedBranch-by-branch solutions for the UX405 e-learning course, each one an exercise in the advanced concepts of a Fiori elements app on a CAP OData V4 service.sap official, cap
