Abstract: Described are system, method, and computer-program product embodiments for automatically ingesting data from disparate data sources into a target database having a target data schema. In some embodiments, the data is received in a data file including data columns formatted according to a data schema, and a data dictionary describing the source data columns. Count data is generated for each cell selected from a data column, each count datum including counts of occurrences of a detected characteristic in each cell. One or more target data columns from the target data schema can be selected and displayed to a user as being semantically related to the data column based on the count data for each cell, a column header of the data column, and the data dictionary. Based on input received from the user, a data table is generated to store the source columns and loaded into the target database.
