1. A computer implemented method, comprising:
storing a partially-structured data in a data management system using at least one key-value pair; 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; and wherein at least one of the storing, the processing, the generating an interface, and the generating the query of data is performed using at least one processor of at least one computing system.
