About the meeting last time [30-Aug-2011]

 Yesterday, I had a short meeting with 2 Profs as usual. About the algorithm, currently it works well. But there are some elements, terms and definitions that I need to clarify them more.
 For example those definition:

• Length of template: actually, the template has a form of tree, so using the name length is incorrect. I have to change it to Level.
• The definitions of new terms: 
• rg, rgp : regular-path-pattern
• tg, t1g, t1gp: template of g-expression, template 1 of g-expression and template 1 of g'-expression
• pf, pg, pgp : pattern of f-expression, g-expresison and g'-expression

 Finally is about the upgrading strategy for multi-variables in the tree, considering the case of different level variables.

• The first advice is trying to reuse the existing functions in the system.
• The second hint is trying to decompose them into many different types. For example:
• Select {view:{a:$x,b:{c:$y}}} where {db:{dba:$x;dbb:$b}} in $db
• So I need to decompose them into many parts, so that I can reuse the current function and just need to compose them to get the result.

 Let's try the new solutions !
