Data is continuously stored in a database, while knowledge accumulated in an accompanying medical dictionary and an accompanying medical knowledge directed acyclic graph.
Claims18
A software system for accessibly storing information from medical data, the software system fixed in a machine readable medium, the software system comprising:
- a) a dictionary of terms, each one of said terms having no more than one meaning;
- b) a relational database storing person-dependent data;
- and
- c) an directed acyclic graph made up of nodes and links between pairs of nodes wherein:
- i. a node represents one said term;
- and
- ii. a link between two nodes represents a finite probability that two terms corresponding to said two nodes coappear in a record of a person in said database
- wherein each database record in said database corresponds to a single person and some of said terms are attributes in said database.

- b) providing a relational database wherein each database record in said database corresponds to a single person and said medical terms are attributes in said database;
- c) describing relationships between said terms using a directed acyclic graph comprising nodes and links between pairs of nodes wherein:
- i. a node represents one said term;
- and
- ii. a link between two nodes represents a finite probability that two terms corresponding to said two nodes coappear in a database record of a person in said database;
- d) for a plurality of persons, from at least one medical record relating to each one of said persons, extracting at least one data item from said at least one medical record, wherein a data item indicates the applicability of at least one of said plurality of medical terms to a respective person;
