Abstract: A method comprises receiving a data set, mapping data points from the data set to a reference space utilizing a lens function, generating a cover of the reference space using a resolution function, clustering the data points mapped to the reference space using the cover and a metric function to determine each node of a plurality of nodes of a graph, generating a graph including the plurality of nodes, the graph including an edge between every two nodes that share at least one data point as a member, and generating first and second data structures, the first data structure identifying membership of each node, the second data structure identifying each edge between each of the two nodes, the second data structure further identifying the nodes that are connected by each edge, the first and second data structure being capable of being queryable using a query language.

Abstract: A computer readable medium includes executable instructions to audit data migration. The executable instructions include instructions to define a data migration path from a source to a target. Audit points are specified within the data migration path. Audit statistics to be generated at the audit points are identified. The audit statistics including data corresponding to individual data values transmitted over the data migration path. Audit rules to be applied against the audit statistics are established.

Abstract: A computer readable storage medium includes computer executable instructions to provide a semantic domain with a plurality of semantic definitions associated with one or more subject areas to a community of users. A data input is received from a user within the community of users. A portion of the data in the data input is linked with a semantic definition from the plurality of semantic definitions to create a mapping. The data input and the mapping are evaluated. The data input is published to the community of users.

Abstract: A computer readable storage medium includes executable instructions to accept a specification of an Extraction, Transformation, Load (ETL) task associated with source data. Source data is profiled to produce profiled data. Data conformance rules are defined from the profiled data. Mapping rules are generated in accordance with the collaborative specification and data conformance rules. The mapping rules are utilized to create an ETL task.
