Simplified Logic, Inc. has the first of its kind knowledge management solution built on Neo4j technology called “nQuery.” nQuery enables customers to define relationship schemas, create item classifications and define/manage item-to-item relationships and compatibility rules. nQuery can be used to constrain end-users, and other business systems, to operate within limits and enforce requirements defined within it. nQuery has multiple integration options. One integration example may be to constrain 3D CAD systems from using parts that are not approved, compatible or available in a target market. Another example would be to validate a product structure and requirements that may be requested by a sales configurator. nQuery was designed as an enterprise-level solution to help customers easily document and leverage typically complex global product compatibility and delivery requirements/limitations.
