Abstract: A system may receive a request to derive an output variable from a source variable. The request may include proposed logic to derive the output variable from the source variable. The system may then compare the proposed logic to existing logic to determine the proposed logic is new. In response to the proposed logic being new, the system may generate transformation code configured to execute the proposed logic. The system may further schedule the transformation code for execution at a predetermined time, and then execute the transformation code to generate data for the output variable.

Abstract: A system may read source data corresponding to a source variable and apply a transformation to the source variable to generate an output variable. The transformation may include logic, and the output variable may be configured for ingestion into a big data storage format. The system may record lineage data of the output variable that comprises the transformation and/or the source variable. The system may also receive a request to generate a requested output variable. The requested output variable may be generated from a second transformation that is the same as the first transformation. The system may thus match the first transformation to the second transformation using the lineage data. In response to matching the first transformation to the second transformation, the system may deny the request. The original output variable may be returned in response to the matching the first transformation to the second transformation.

Abstract: A system may store a plurality of first records comprising a first variable in a first data storage format. The system may also store a plurality of second records comprising a second variable in a second data storage format. The first data storage format may have a different data structure than the second data storage format. The system may then generate a catalog including a first location of the first variable and a second location of the second variable. The first location identifies the first data storage format, which is where the first variable is stored. The second location identifies the second data storage format, which is where the second variable is stored. The system may then receive a request to access at least one of the first variable or the second variable and access the first variable and/or the second variable in response to the request.

Abstract: A system may register a use case with the use case including an application. An application identifier may be assigned to the application. The system may generate a transformation associated with the use case. The transformation may include logic to derive an output variable from a source variable. The system may also execute the transformation to derive output data for the output variable from source data of the source variable. The system may further lookup an access permission for the application using the application identifier in response to an access request.

Abstract: A system may retrieve a pattern from a pattern database with the pattern identifying a type of sensitive data. The system may also retrieve data identified by a variable from a big data management system. The system may then match the data to the pattern to detect the type of sensitive data in the data. An output may be generated in response to the data matching the pattern. A variable access permission may be retrieved for the variable from a permissions repository, a sensitive data permission may be retrieved for the type of sensitive data from the permissions repository, and the variable access permission may be compared to the sensitive data permission to detect a discrepancy.

Abstract: A system may receive a request for access to a first variable. The request may include a requested action and a variable identifier for the first variable. The request may also have a syntax that is incompatible with first data storage format. The system may parse the request to capture the variable identifier from the request. The system may also look up a location of the first variable in a catalog using the variable identifier. The location of the first variable may include the first data storage format. The system may generate a query to access the first variable. The syntax of the query may be compatible with the first data storage format. The system may then submit the query to the first data storage format. The query may be configured to complete the requested action.

Abstract: The eccentric assembly includes a tubular section, an eccentric weight, and a counterweight. The eccentric weight is mounted within the tubular section such that as a motor rotates the eccentric assembly, the eccentric weight generates vibrations that are transferred to the drum assembly of the vibration compacting machine. The counterweight is slidably coupled to the eccentric weight and moves between a first position where the counterweight contacts the eccentric weight and a second position where the counterweight contacts the tubular section.
