The process includes receiving a data set comprising a plurality of rows and a plurality of columns, and applying a first rule based decisioning to the data set to generate a first layer of metadata that comprises at least one of a key, a type indicator, a categorical indicator, and/or a continuous indicator. The first layer of metadata may be descriptive of the data set. The processor may further apply a second rule based decisioning to the first layer to generate a second layer that includes at least one of the key, the type indicator, the categorical indicator, or the continuous indicator. The second layer may be descriptive of the first layer. The process may also include generating an output file from at least one of the first layer or the second layer.

Rule based decisioning on metadata layers

A system for applying access permissions to read requests may write a file to a storage media. The file may contain data, an embedded flag, and an embedded verification datum of the embedded flag. The embedded flag may indicate an access permissions requisite for file access. The system may also receive a request to access the file from a user and retrieve an access permission for the user. The system may also compare the embedded flag to the access permission for the user to determine the user has permission to access the file. A verification datum may be calculated, and the calculated verification datum may be compared to the embedded verification datum to determine the embedded flag has not changed.

Permissions for writing data to a file

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.

Data transformations with metadata

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.
