US 11,531,651 B1 · Dynamic data schema service

Abstract

A dynamic schema service (DSS) stores and vends data schema for use by one or more client services. Each schema includes one or more data fields that describe related entities. The DSS also stores meta-schema, which defines limits for field definitions in the schema and other constraints. Using the DSS, a service owner defines fields and constraints unique to its business application and can revise those fields and constraints over time. When the client service requires a schema, the client service sends a request to the DSS, and the DSS responds with the current version of the schema for use by the client service. Service owners are able to edit their schemas in DSS, and the changes are immediately implemented in the corresponding services by virtue of the schema request to DSS. In some embodiments, the DSS employs a hierarchical graph structure to determine the requested schema.

Dependent claims

A computer-implemented method, comprising:

storing, for a client service, a hierarchical graph and corresponding meta-schema and constraints, the hierarchical graph comprising a plurality of levels and a plurality of vertices interconnected by edges, each vertex being associated with one of the levels and corresponding to a respective entity, at least one data field being defined for each vertex;
receiving, at the client service, a client request related to a first entity;
receiving, at a dynamic schema service, a first service request from the client service for a first schema associated with the first entity, the first entity corresponding to a first vertex in the stored hierarchical graph;
building the first schema associated with the first entity by aggregating the data fields defined for each vertex in the levels higher than the first vertex and connected to the first vertex, with the at least one data field defined for the first vertex;
and
at the client service, using the first schema associated with the first entity and the corresponding constraints from the dynamic schema service to satisfy the client request.

3 more elements

One or more non-transitory computer-readable storage media collectively storing computer-executable instructions that, when executed by one or more computing devices, configure the one or more computing devices to collectively perform operations comprising:

receiving a request for modification of a first schema based on a hierarchical graph structure having a plurality of levels and a plurality of vertices interconnected by edges, each vertex being associated with one of the levels, at least one field being defined for each vertex, the modification comprising changing a field in the first schema, deleting a field in the first schema, defining a new field in the first schema, or any combination thereof;
determining that the requested modification is valid using meta-schema associated with the hierarchical graph structure, the meta-schema comprising one or more definitions of valid field types, required field properties, valid field properties, conditional constraints, or any combination thereof;
and
in response to the determining that the requested modification is valid, performing the requested modification of the first schema.
