Schema-less access to stored data

A computer program product comprising a machine-readable medium storing instructions that, when executed by at least one programmable processor, cause the at least one programmable processor to perform operations comprising:

• storing a partially-structured data in a data management system using at least one key-value pair;
• and
• processing, using the data management system, a query of data, wherein the query is generated using a structured language;
• generating an interface containing a plurality of columns of data, wherein each column in the plurality of columns corresponds to a key in a plurality of stored key-value pairs;
• and
• generating, using the generated interface, the query of data using the structured language;
• wherein the generated query refers to at least one column in the generated interface;
• wherein the plurality of columns includes a physical column stored in the data management system and a virtual column stored in an overflow column in the data management system, the overflow column contains at least one key-value pair having a key that is not associated with the physical column stored in the data management system.
