Abstract: Systems, methods, and computer-readable storage media. A system includes one or more processing circuits to identify a modification or update of unstructured data stored in an upstream source, determine a new schema of the unstructured data using a function, the function based on at least one of a pattern, a transformation, an inference, or a correspondence between the unstructured data and a previous schema, determine a difference between the new schema and the previous schema, generate structured data corresponding to the unstructured data, and store the structured data as a representation within the database of the modification or update of the unstructured data.

Abstract: Disclosed are systems and methods for maintaining data integrity (e.g., of a database, a data lake, etc.). In some embodiments, one or more processing circuits identify an update, insertion, or deletion of unstructured data stored in an upstream source. The processing circuits determine a new schema of the unstructured data using an inferring function and further determine a divergence between the new schema and a previous schema of the unstructured data based on comparing the new schema to the previous schema of the unstructured data. In an example, the processing circuits store the structured data in a database. The database includes an established data channel between the database and a downstream source, and the structured data is a unique representation within the database of the update, insertion, or deletion of the unstructured data.
