A system comprising:

• a storage to store:
• a first database table representing a structure of a document formatted in a markup language and having a plurality of nodes organized in a tree structure, the first database table having a plurality of rows, each row corresponding to a node of the document and
• storing at least a unique numerical identifier for the node;
• and,
• a second database table storing text values of the nodes of the document, the second database table having a plurality of rows, each row corresponding to a node of the document and storing at least a text value of the node by the unique numerical identifier for the node;
• and,
• an access component to receive query operations to access the document against the first database table and the second database table.

A computer-readable medium having a computer program stored thereon to perform a method comprising:

• parsing a document formatted in a markup language and having a plurality of nodes organized in a tree structure;
• for each node of the document,
• storing a unique numerical identifier for the node in a row of a first database table representing a structure of the document;
• storing a unique numerical identifier of a parent node of the node in the row of the first database table;
• storing a unique numerical identifier of a last descendant node of the node in the row of the first database table;
• and,
• storing a text value of the node in a row of a second database table by the unique numerical identifier for the node, the second database table storing the text values of the nodes of the document,
• wherein the document is accessible by query operation against the first database table and the second database table.
