  • Publication number: 20210318995
    Abstract: Techniques and solutions are described for determining a set of elements of a second set that may correspond to a given element of a first set of elements. The elements can be, in specific examples, components of a database system, such as tables (or entities), attributes, or records. Significance metric values are calculated for elements in the first and second sets. The significance metric values can be a number of records in an entity or a number of read or write access operations for an entity or for a record of an entity. A significance metric value for the given element can be used at least in part to select elements of the second set as potential match candidates, based at least in part on significance metric values for elements of the second set. Selecting elements can include selecting elements based on a window of elements of the second set or a range of significance metric values.

  • Publication number: 20210232591
    Abstract: Transformation rule generation and validation functionality is provided herein. Transformation rules can be generated for one or more mappings in an alignment between a source database and a target database. The transformation rules can transform instance data from the source data model to a form matching the target data model. One or more transformation rules can be generated for a mapping between fields in a source database and a field in a target database. The transformation rules can be generated based on one or more source fields and a target field of a mapping, and one or more identified functions. Evaluating the transformation rules can include generating test data based on the transformation rules applied to instance data from the source database. The test data can be evaluated against instance data from the target database. The transformation rules and the evaluation results can be provided in a user interface.

  • Publication number: 20210073655
    Abstract: Smart rule development and rule mining functionality is provided herein. Rule mining for use in rule development can include generating logic statement proposals, rule deduplication, and rule template generation. Rule mining can include accessing a rule set to analyze the rule set against an input logic statement to identify existing rules which match at least in part the input logic statement. Rule deduplication can include returning exact rule matches to replace the input logic statement. Proposing logic statements can include returning logically related rules from rules found that include the input logic statement. Generating rule templates can include returning a template based on the entire rule(s) which includes the input logic statement. Ranking scores can be calculated for returned rules, whether for deduplication, proposals, or template generation. The scores can be based on statistical information for the rules, such as usage of the rule or coverage of the rule.

  • Publication number: 20210012219
    Abstract: Automatic rule generation is provided herein for generating data mapping, data transformation, or process flow rules or logic statements. The rules may be generated based on a field or attribute, and may be further based on a partial rule or one or more existing rules, or a combination thereof. Proposed rules may be generated based on analysis of a data set, including identifying possible values for the attribute and to calculate scores for the possible values. A score may be the probability of the value based on the data set. The data set may be cleaned or scrubbed based on the partial rule or existing rules. The proposed rules may be provided to a user, or may be automatically selected. Rule generation may include constraint checking. Constraint checking may include detecting empty data sets or detecting when two rules are not mutually exclusive.

  • Publication number: 20200349129
    Abstract: A method for aligning data model schemas is provided herein. A first schema and a second schema may be received. The schemas may include sets of nodes and links between the nodes. An anchor point between the first schema and the second schema may be received. A source node in the first schema may be identified to be mapped to the second schema. A source distance may be calculated between the source node and the anchor point in the first schema. Option distances may be calculated between the anchor point and the other nodes in the second schema. Penalty scores may be calculated for the option distances. A mapping node may be selected from the nodes in the second schema based on their penalty scores. A new anchor point identifying a correspondence between the source node and the mapping node may be stored.

  • Publication number: 20200349128
    Abstract: A method for data model clustering is provided herein. A first representation of a data model may be received. Edge betweenness values may be determined for respective nodes in the first representation. At least one node in the first representation may be identified as a linking node based on the respective edge betweenness values. One or more linking nodes may be removed from the first representation, thereby forming at least a first cluster and a second cluster. Degrees for the respective remaining nodes may be calculated. Respective hub nodes may be identified for the respective clusters based on the respective degrees in the clusters. Respective descriptions may be generated for the respective clusters based on the respective hub nodes. A clustered representation of the first representation may be stored with the clusters and their respective descriptions.

  • Publication number: 20200342007
    Abstract: Techniques and solutions are described for determining, evaluating, and selecting data retrieval pathways. A plurality of database objects, such as tables, can be retrieved, and relationships between them determined. The relationships are between various attributes of the database objects. A plurality of pathways are determined between at least two target database objects, where the path determination does not consider attribute-level relationship information. After a path is determined, the relationship-level information can be added. A summary of the path, and relationship information, can be displayed to a user. A user can select paths to remove from the display, and can indicate one or more database objects that are required for a valid path, one or more database objects that are prohibited from valid paths, or combinations thereof. A user can select a path, and a query language statement to implement the path can be generated and displayed to the user.
