A Standard Design Pattern for eGov
Administrative Processes

This publication describes the conception, design, validation and use of a standard common pattern for automating e-Government (eGov) administrative processes and covers the normal common activities of public administrative processes—theoretically of any size—representing an estimated 80% of development requirements. This study was carried out on Nicaraguan Public Administration which manages around 1,200 administrative processes. If 80% of the logic of each of these processes can be automatized with the services proposed pattern, the savings can be considerable.This study identifies basic services following the mainstream SOA service models: entity, task, orchestrated task and utilities and also identifies two potential new service models, the catalogs and the public IT registries. In addition, it also identifies a new candidate design pattern, the Hybrid Service Inventory design pattern but does not elaborate on it. With thousands of administrative processes to automate, the public administrations of most e-governments would benefit from a standard, common design for the automation of their administrative processes, particularly if they have adopted SOA and if the pattern is based on a number of...

New Data Analytics

Paul S. Prueitt

Human knowledge transfer commonly occurs on digital platforms within industry training programs, in schools, and in colleges. A necessary part of digital knowledge based transfer systems is the enumeration of categories, and thus the rise of categorical analytics as an important sub-discipline of data science. Since this sub-domain is not yet well known, we cite Katzan's entire abstract for his 2008 article: "Categorical analytics is an admixture of computational methods with the express purpose of facilitating the multifaceted process of unstructured decision making. The complex subject is based on consensus theory and includes structured analytics, categories, entropy, and the combination of evidence. The methodology is applicable to a wide range of business, economic, social, political, and strategic decisions. The paper includes an election application to demonstrate the concepts." Katzan's approach is based on probability and is covered more extensively in his book. Our approach in this article is consistent with Katzan's, but stresses a specific "stratified model" in the development of a set of substructural categories, and...

Service Architecture – The Importance of Standardized Modeling – Part II

Mario Mesaglio

According to serviceorientation.com, a Message Processing Logic can be defined as: "… A fundamental part of a physical Web service architecture. It typically exists as a combination of parsers, processors, and service agents, many of which are provided by the runtime environment... Examples of message processing logic include message validation, message data transformation, and message header processing." This relates mainly to Service as a Web-Service architectures. Despite that, the MPL should be taken as a fundamental block of any service architecture, not only related to web-service technology approaches so as to increase the applicability of the "Decoupled Contract" design pattern. Scenarios where WS technology is not chosen for exposing the service endpoints are rare, but nevertheless there should not be a distinction about where to use an MPL component on a standard service architecture. A clear definition will be made on where messaging/support and business/utility-driven logic within service architecture must be placed in order to promote a physically separate implementation of each one. This approach is the most effective for attaining agility on service general implementation changes, Software...
