The method includes receiving historical data from a first data source; analyzing the historical data for a desired characteristic; determining a representative value for the desired characteristic of the historical data; determining a first data expectation for the historical data based on the representative value; transmitting the first data expectation to a first data recipient; receiving first incoming data from the first data source; analyzing the desired characteristic of the first incoming data; determining a first incoming data value for the desired characteristic for the first incoming data; comparing the first incoming data value and the representative value; determining a first difference between the first incoming data value and the representative value; and/or comparing the first difference to a difference threshold which indicates whether a difference between an incoming data value and the representative value is significant.

Data management system

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.
