Resource Cost Problem: How to pull relevant information from disparate systems using different software and hardware and report formats, into a common report. Solution: Web services Problem: How to pull relevant information from disparate systems using different software and hardware and report formats, into a common report. Solution: Web services

Resource Cost Using old technology, linking systems required the development of an elaborate superstructure of hardware and software built around specific exchanges between specific systems using lots of client side software. The expense of these systems in both personnel and financial resources was tremendous.

Resource Cost During the last 18 months, new software tools have become available that for the first time allow ‘practical’ solutions to linking systems. These tools make it easy for users to build linkages to dissimilar systems using Web services and XML instead of specific client side software solutions. The cost of doing this has dropped by a factor of 10. What used to cost 1M$ to do can now be done for 100K.

Resource Cost With the new Web based technologies and standards it is possible to dramatically accelerate the pace of the development process; drastically reduce the cost in manpower, software, and hardware; and greatly simplify the adaptability of the solution to new demands and needs. The difference in the scale of the solution that is now possible compared with what was possible before introduction of these Web technologies is analogous to the difference between a minicomputer from 1980 and a laptop computer of With the new Web based technologies and standards it is possible to dramatically accelerate the pace of the development process; drastically reduce the cost in manpower, software, and hardware; and greatly simplify the adaptability of the solution to new demands and needs.

Presentation to Justice Information Sharing Conference November, 2003 A service-oriented architecture is essentially a collection of services. These services communicate with each other. The communication can involve either simple data passing or it could involve two or more services coordinating some activity. Some means of connecting services to each other is needed. Service-oriented architectures are not a new thing. The first service-oriented architecture for many people in the past was with the use of DCOM or Object Request Brokers (ORBs) based on the CORBA specification.

Presentation to Justice Information Sharing Conference November, 2003 ServicesServices Services are what you connect together using Web services. A service is the endpoint of a connection. Also, a service has some type of underlying computer system that supports the connection offered Web services Web services technology is the most likely connection technology used in service-oriented architectures. Web services essentially use XML to create a robust connection. XML Web services XML Services are what you connect together using Web services. A service is the endpoint of a connection.
