Abstract: Techniques are provided for automated query modification using graphical query representations. One method comprises obtaining a query referencing multiple fields in one or more information elements; generating a graph of the query by: establishing nodes for referenced fields; connecting the established nodes corresponding to referenced fields from a same information element using one or more edges; adding edges, for operations in the query that establish a connection between information elements based at least in part on a related field in the information elements, to connect the nodes corresponding to the related fields; and setting a status of nodes corresponding to fields that are selected in the query to a selected status; and initiating an automatic generation of a modification of a portion of the query based at least in part on the graph. The modification may comprise a correction, completion and/or enrichment of the query.

Abstract: A data encryption, decryption, and storage method includes: receiving a first query request to retrieve a production data; obtaining a constructed data and encrypting the constructed data using the production data to obtain an encrypted constructed data where the encrypted constructed data is generated without including metadata specifying an access list specifying one or more users and types of users that are able to access the encrypted constructed data; and generating decryption instructions using the production data and storing the decryption instructions with the encrypted constructed data.
