Abstract: A method, apparatus, and non-transitory computer readable medium for performing joins on data from hierarchical databases are described. The method, apparatus, and non-transitory computer readable medium may provide for receiving one or more search results from each of a plurality of hierarchical databases, identifying one or more matching fields from each of the search results, joining the search results according to a set of rules for processing related fields to the matching fields, wherein the related fields comprise sibling fields, neighbor fields, ancestor fields, descendant fields, or any combination thereof, and generating one or more combined search results based on the joining.

Abstract: A parameter of a first checker in a profile of the first checker is configured. The parameter comprises a restriction on contents of a modification to a dataset. The modification comprises a write to a portion of the dataset. The dataset is modifiable by a plurality of authors. The first checker has a first checker owner. A first modification to the dataset is validated against a restriction enforced by the first checker according to the parameter. The first modification has a modification owner. Responsive to the validating detecting that the first modification is acceptable, the first modification is allowed.

Abstract: A computer-implemented method of automatically identifying a product offering for a customer using a generated decision tree from a directed acyclic graph knowledge base is described. The method includes, by a processor, identifying a set of product offerings, where each product offering is described by a file. The method converts each file into a Directed Acyclic Graph (DAG) and clusters the DAGs. For each cluster, the processor creates a decision tree to distinguish between the product offerings.
