Running your own SDK-based FIDO server requires data storage. Most of the data processed by the protocol classes needs to be persistent; the recommended approach is to use a relational SQL database. The SDK package contains the db-schema.sql file, with CREATE statements that can be executed in your database to generate the correct data structure.
Table: Required database tables contains a brief description of each database table required by the SDK.
Table: Required database tables | Table name | Description |
|---|
| DISPLAY_PNG_CHARACTERISTICS_DESCRIPTORS | PNG image characteristics, including width, height, bit depth, compression, etc. |
| ASSERTIONS | Representation of a registered key specified by the application ID, user name, and authenticator. |
| RGB_PALETTE_ENTRY | Three-sample RGB palette entry. |
| POLICIES | Contains specifications of accepted and disallowed authenticators. |

| MATCH_CRITERIA_ASSERTION_SCHEMES | Table containing mappings between match criteria and assertion schemes. |
| MATCH_CRITERIA_ATTESTATION_TYPES | Table containing mappings between match criteria attestation types. |
| MATCH_CRITERIA_AUTHENTICATION_ALGORITHMS | Table containing mappings between match criteria and authentication algorithms. |
| MATCH_CRITERIA_EXTENSION | Table containing mappings between match criteria and the extension. |
| MATCH_CRITERIA_KEY_IDS | Table containing mappings between match criteria and key IDs. |
