Design Server
The documentation provided here describes how to use the Design Server.
- Projects
  This documentation describes Design Server projects.
- Schemas
- Maps
- Flows
  A flow node invokes a sub flow within a flow. Sub-flows need not be wired to other nodes; it is valid to have a flow that is comprised of multiple sub-flows that each have listeners.
- Using Design Server
  How to use the HCL Link Design Server.
- Flows
  This documentation describes how Flows can be run from REST API, listeners, or they can be scheduled.
- Schema designer
  Use the schema designer to define, modify, and view schemas. A schema describes the syntax, structure, and semantics of your data.
  - About schemas
    A schema defines the contents of at least one input that you intend to map or one output you intend to map.
  - Subtypes
  - Schema hierarchy
  - Defining data
  - Objects, types, and classes
  - Testing part of a schema
    You can test a schema by generating test data for an item or a group. The schema designer creates source and compiled maps that generate and validate the test data. The test-data-generation map automatically runs and produces a text file with the sample data. After that, the test-data-validation map automatically runs on the sample data file.

Schema Analyzer errors and warnings

The Schema Analyzer checks the logic and internal consistency of your data definitions. Schema analyzer error and warnings messages are issued on the type of analysis that is performed: logic and structural.

Logical analysis addresses the integrity of the relationships that you define in the schema.
Structural analysis addresses the integrity of the underlying database.

Warnings indicate a successful analysis and are relatively insignificant. Warning messages provide information about inconsistencies that occurred, when the schema was changed, and were automatically resolved.

Errors are important. Error messages provide information about errors in your type definitions that you should correct. An error may result in unpredictable results in your mapping.

Words in italics represent information that varies, indicating information specific to the type for which the message is generated.
