Data storage system

A method comprising:

• receiving from a data system interface, details of a request issued by a requester to retrieve content data from a database system, together with non-content data relating to a data object stored in a data object storage;
• in which the non-content data are retrieved from the database system;
• forwarding to the data object storage, the details of the request and the non-content data;
• receiving from the data object storage a response, in which the response comprises a data object comprising the content data;
• and
• forwarding to the data system interface the content data.

A system comprising a data system interface in which the data system interface comprises:

• a first interface for communicating with a requester device;
• in which the first interface is configured to receive from the requester device, a request to retrieve a data object from the database system;
• a second interface for communicating with a database system;
• in which the second interface is configured to forward details of the request to the database system;
• and
• to receive a response from the database system, in which the response comprises metadata relating to a data object stored in a data object storage;
• and
• a third interface for communicating with a data object storage through an object storage interface;
• in which the third interface is configured to forward to the object storage interface details of the request, the metadata.

A system comprising:

• a data object storage interface in which the data object storage interface comprises:
• a first interface for communicating with a data system interface and through the data system interface with a requester and a database system;
• in which the first interface is configured to:
• receive from the data system interface, details of a request, issued by a requester, to retrieve content data from the database system;
• receive from the data system interface, non-content data relating to a data object comprising the requested content data stored in a data object storage;
• and
• forward to the data system interface for delivery to the requester, content data comprised in a data object received from the data object storage;
• a second interface for communicating with the data object storage;
• in which the second interface is configured to:
• forward to the data object storage details of the request and the non-content data;
• and
• receive from the data object storage in response to the request a data object.
