Structured Data (XML)
Data with Modeling Information
Data with Program CodesProgram Driven vs. Data Driven
Information for processing is hard-coded in program
Processing instruction is hard-coded in data?!
Tree(1) is accessible frompoint A, occasionally, a query
(e.g. [A, “spatial-search”,(3, 5)],
assuming Tree(1) will accept
spatial-search with two coordinates)
may return point B as answer,
either by XPath of B or the
XML subtree of B.
From this point B, user may drill down the tree by issueanother query on Tree(2).
The Abstract Class defines common interface that have to be implement in each MMX Element such as LIST-OPERATION, QUERY, BUILD, etc.
