Abstract

The invention consists of expanding field types in a Relational Database Management System (RDBMS) by introducing a new field type, called class, for field definitions in a RDBMS. The field identifier for this field type will be prefixed with the token 'class' and will include the name of a class. This association of field contents and classes will provide significant performance advantages in image processing, data mining, on-line analytical processing (OLAP) applications, and other high rate data reception and processing applications as described below.

Relational Database Management System with Class

This invention comprises of defining a new field type for RDBMS field definitions. The new field type is called a class (

just like double, float, etc.) The field type not only hold

the data (or pointers, names, and locators of the data), but also includes a mechanism that identifies the name of the class that is designed and developed to process the data; the class could be an API class. For example, a field of type class can be defined and named as class:detectSoftTissueOneCm in an RDBMS. The column in the RDBMS will store, for example, the pixel data from a Computer Tomography (CT) scanner and detectSoftTissueOneCm is the name of the class that will process the pixel data and identify tissue masses of 1 centimeter or more in size in the image.

The invention is best illustrated by an example. Consider a computerized medical imaging system. As the image data from a device like an CT scanner comes into the computer, the computer has to process the numeric data that corresponds to each pixel. The computer receives 2 D pixel data and meta data and stores it in a database. Then
it processes the data and meta data to create a 3 D volumetric images from the 2 D data. The current state of the art heretofore is to gather the 2 D data and meta data as
a first step and then process the data to create the 3 D volumetric image for physicians to use. The creation of the image followed by the evaluation of the image and, if necessary, any further processing by a computer, is done as subsequent steps.

With the present invention, as the 2 D pixel data and meta data is being received and stored in the database, the class or the classes associated with the pixel data and the meta data are invoked as the data are being received and written into the database. The appr...
