1. A method of accessing information within a directory tree structure comprising the steps of: a. formatting a searchable database into the directory tree structure, wherein the directory tree structure includes nodes comprising a collection of related data and branches comprising links between the nodes, further wherein each specific node provides a corresponding set of parameters by which each related item of data corresponding to the specific node is defined by initializing a value of each parameter for each related item of data; b. accessing a particular node within the directory tree structure; c. setting one or more search parameters corresponding to the set of parameters of the particular node; and d. performing a parametric search using the one or more set search parameters corresponding to the specific node to generate one or more matching discrete data items, wherein each matching item corresponds to related items of data of the particular node.
