The disclosure includes a method for retrieving information stored in a cloud capable database. —A user has an OPC UA client, which is connected for communication with an OPC UA server, wherein the OPC UA server is used for the creating, aggregating and conforming of information models, wherein the OPC UA server interacts with an API for accessing the database, including: creating and loading a user-specific information model into the OPC UA server by using the configuration module, wherein the user-specific information model defines one or more pieces of information to be queried from the database; querying information defined in the user-specific information model from the database using the API and transferring the information from the API to the OPC UA server; converting the queried information into OPC UA-conforming structure data; and sending the structure data from the OPC UA server to the OPC UA client.
