Introduction: -
Corporation Information Management System (CIMS) is an Integrated Information Management System for Municipal Corporations, which is designed specially for Indian environment but having an international standard of applicability. High Resolution Satellite (IKONOS) Data has been used for preparation of land base data so that a high level of accuracy can be maintained, especially for locating and assessing the Corporation’s immovable property e.g. Building, Roads, and Parks etc.

Idea behind designing CIMS is to provide an e-governance solution, which would be cost effective, and which would provide a real world scenario for the planners and decision makers to work with. After reviewing the tools available in the market, our search ended with PARIS.

PARIS (Parametric rule Based Information System), as evident from its name, is a kind of tool, which is driven by set of rules which can be defined by a user as per his need.

PARIS Technology is based on OOPS Concept, which in turn is based on concept of real world modeling. This helps PARIS to provide a possible real world scenario, an ultimate objective of any GIS solution. Still most of the GIS solutions are working on the principle of “Entity” rather than concept of “Object”. When an entity inherent certain characteristic of its class, it becomes an Object e.g. a line drawn in any GIS package may represent a Cable or a Pipeline for a user. But for system, it’s nothing but an entity. Only we are assuming that it’s a Cable or a Pipeline. Of course, we can assign some value in the form of attribute data for the sake of analysis based on our requirement as Cable No, Type or Voltage etc. But it is not making any difference in the nature of entity inside the system. Still an entity that is representing a Cable can be connected with another entity, which is representing a Pipeline. Is it possible in real world? Answer should be the no! If these “Entity” had been the “Object”, it would not have happened because a Cable in terms of its use and characteristics is different from a Pipeline.

GIS solutions based on PARIS technology works on the concept of object, driven by user-defined rules. For example, as a Pipe with 80 mm diameter cannot be connected with to a pipe, which does not have same diameter without a connecting sleeve of appropriate diameters. Similarly a one way road should not be included for calculating the shortest path between two places if that road is not allowing traffic from the starting point to destination point’s direction.

Let us see the architecture of PARIS and how an object is created and administered.

PARIS Architecture: -
PARIS has been developed on Client and Server architecture and can be divided into four modules based on their functionality as given below

1. Administration
2. Modeling
3. Data Capturing
4. Analysis and Data Display
