State of Colorado – Dept. of Wildlife – Refunds Processing Migration
Background Business Case The Colorado Department of Natural Resources, Division of Wildlife (CDNR-CDW) was spending an inordinate amount of time and money maintaining their collection of legacy applications that included: Colorado Outdoor Recreation Information System (CORIS): a High Volume Refunds Processing system, Cash Management system, Hunter Education system, and a License Administration system. In addition, CDW required the development of a custom Workflow Foundation for increasing the automation and efficiency of their batch processing activities. The department’s existing legacy systems did not meet the CDW Information Technology Architectural Standards. This meant that any new application and infrastructure components were to be developed to meet CDNR-CDW’s current Information Technology Architectural Standards.
Solution The CDNR-CDW selected Estrada Consulting, Inc. (ECI) and their team of Service Oriented Architecture (SOA) development experts to design and build a suite of new Microsoft .NET applications to meet the needs of CDNR-CDW as follows: High Volume Refunds Processing System ECI worked collaboratively with CDNR-CDW stakeholders and IT resources to co‐develop a new High Volume Refunds Processing System that provides the same core functionality as the legacy Colorado Outdoor Recreation Information System (CORIS). The new system uses a custom developed Workflow Foundation Framework that leverages Microsoft .NET Windows Workflow Foundation (WF), and provides the following functionality:
ECI successfully implemented this new system by developing a suite of services provided by Microsoft .NET Windows Communication Foundation (WCF) that support data contracts, message contracts, service contracts, service implementations, and fault contracts.
ECI also developed a custom user interface using Microsoft .NET / ASP.Net that allows users to set processing input parameters, and provide feedback to the user during processing. This included development of Microsoft SQL Server stored procedures for CRUD (Create, Retrieve, Update and Delete) operations, and successful unit and system testing.
Cash Management System ECI worked collaboratively with CDNR-CDW stakeholders and IT resources to co‐develop a new Cash Management System that replaced the legacy processin capability of the Colorado Outdoor Recreation Information System (CORIS). The new system was developed as a Microsoft .Net Smart Client solution that uses a custom developed Workflow Foundation Framework which leverages Microsoft .NET Windows Workflow Foundation (WF), and provides the following functionality:

Workflow Foundation Framework ECI worked collaboratively with CDNR-CDW stakeholders and IT resources to co‐develop a Workflow Foundation Framework using Microsoft .Net Windows Workflow Foundation (WF). This framework facilitates the development of large scale database batch processing that includes:
ECI successfully implemented the framework by developing a suite of services provided by Microsoft .NET Windows Communication Foundation (WCF) that support data contracts, message contracts, service contracts, service implementations, and fault contracts – as well as a suite of workflow processes provided by the custom Workflow Foundation Framework developed using Microsoft .Net Windows Workflow Foundation (WF).
Highlights Serviced Oriented Architecture ECI developed the CDNR-CDW solution by way of a Service Oriented Architecture (SOA) that provides methods for systems development and integration, packaged as interoperable services. A SOA infrastructure allows different applications to exchange data with one another. Service-orientation aims at a loose coupling of services with operating systems, programming languages and other technologies that serve as the framework for applications. SOA separates functions into distinct units, or services, which developers make accessible over a network. This insures that users can combine and reuse them in the production of applications. Communication is facilitated by passing data from one service to another, or by coordinating an activity between two or more services using Microsoft .NET Windows Communication Foundation (WCF). Workflow Based Solution The term workflow is used in computer programming to capture and develop human-to-machine interaction. Workflow-enabled software aims to provide end users with an easier way to orchestrate or execute complex processing of data in a visual form, without the need to understand computers or programming. ECI developed the CDNR-CDW solution to enable workflow through the use of the Microsoft .Net Windows Workflow Foundation (WF) allows programmers to define, execute and manage workflows. Workflow communication is facilitated by Windows Communication Foundation (WCF) which provides a service interface for interacting with Workflow activities. OSHPD realized many expected and unexpected benefits from the development of a new Annual Financial Database including: ECI Role ECI’s team of consultants has been instrumental in the successful implementation of the CDNR-CDW applications and infrastructure. ECI’s responsibilities included:
ECI’s team of consultants used the latest tools and technologies to deploy the solution at CDNR-CDW including:
