Approved for public release, distribution is unlimited / A thorough examination of the Secure Application Integration Methodology (SAIM) for applicability in the Department of the Navy (DON) would provide useful information about a beneficial methodology. SAIM is analyzed, by accessing its step by step directions, for suitability in the integration of the Enterprise Resource Planning (ERP) projects implemented by the SYSTEMS COMMANDS (SYSCOMS). The Navy Enterprise Convergence Team (NECT) that leads the ERP integration effort could benefit from a sound Enterprise Application Integration methodology. Results do not support SAIM as the sole guiding EAI methodology however it could have some value to the NECT. SAIM has three primary benefits which NECT could employ: 1) It provides a complete walkthrough of the EAI process, 2) It emphasizes the importance of an Enterprise Architecture, and 3) It provides useful management checklists along with other important considerations. SAIM also has some significant shortcomings: 1) It does not support all the DON Chief Information Officer requirements, 2) It does not provide Change Management Guidance, 3) It does not take into account the uniqueness of the Navy's environment, and finally 4) SAIM relies on an Enterprise Architecture as its foundation which the Navy does not currently have. / Lieutenant Commander, United States Navy

Electronic message transfer is the key element in enterprise application integration (EAI) and the privacy of data transferred must be protected by the systems involved in the message transfer from origin to the destination. The recent data privacy regulation such as GDPR (General Data Protection Regulation) has enforced the organizations to ensure the privacy of the personal data handled with obligations to provide visibility and control over to the data owner. Privacy concerns with relevant to sensitive data embedded and transferred through business-to-business (B2B) middleware platforms in enterprise architecture are mostly at risk with the legacy nature of the products and the complexity of system integrations. This poses a great threat and challenge to organizations processing sensitive data over the interconnected systems in complying with regulatory requirements.  This research proposes a solution design to address the data privacy issues related to personal data handled in an enterprise application integration framework. Where electronic messages used to transfer personally identifiable information (PII). The proposal consisting of a design called “Safety Locker” to issue unique tokens related to encrypted PII elements stored in a persistence data storage based on Apache Ignite. While adding REST API interfaces to access the application functionality such as tokenization, de-tokenization, token management and accessing audit logs. The safety locker can run as a standalone application allowing clients to access its functionality remotely utilizing hypertext transfer protocol (HTTP). The design allows the data controllers to ensure the privacy of PII by embedding tokens generated from the application within the electronic messages transferred through interconnected systems. The solution design is evaluated through a proof of concept implementation, which can be adapted, enhanced to apply in EAI implementations.

<p>U sklopu doktorske disertacije izvršeno je istraživanje vezano za<br />automatizaciju integracije poslovnih aplikacija. Prikazani pristup<br />kombinuje model strukture interfejsa aplikacija koje se integrišu sa<br />formalnim opisom njihove semantike, datim u vidu ontologije. Na<br />osnovu ovih izvora, obavlja se automatsko mapiranje među elementima<br />interfejsa koji se integrišu, kao i detekcija i razrešavanje<br />semantičkih konflikata. Razvijena je praktična implementacija<br />predloženog pristupa, koja je korišćena za verifikaciju teorijskih<br />razmatranja, a uključuje adaptivan radni okvir i jezik specifičan za<br />domen. Predloženi pristup je verifikovan na dva realna<br />integraciona scenarija i jednim eksperimentom.</p> / <p>This thesis presents a research in the field of automation of enterprise<br />application integration. The approach combines structural models of<br />interfaces of the applications being integrated with a formal specification of<br />their semantics, given in form of an ontology. Using information from these<br />sources, automated interface mapping is performed, along with detection and<br />resolution of semantic conflicts. A practical implementation of the presented<br />approach was developed and used to verify theoretical considerations. The<br />implementation includes an adaptive framework and a domain specific<br />language. The proposed approach has been verified on two real-world<br />integration scenarios and one experiment.</p>

Due to the changing scope of data management from centrally stored data towards the management of distributed and heterogeneous systems, the integration takes place on different levels. The lack of standards for information integration as well as application integration resulted in a large number of different integration models and proprietary solutions. With the aim of a high degree of portability and the reduction of development efforts, the model-driven development—following the Model-Driven Architecture (MDA)—is advantageous in this context as well. Hence, in the GCIP project (Generation of Complex Integration Processes), we focus on the model-driven generation and optimization of integration tasks using a process-based approach. In this paper, we contribute detailed generation aspects and finally discuss open issues and further challenges.

The purpose of this project was to explore the use of Web services to solve enterprise computing problems. XML-based Web services allow complex information systems to be subdivided. In order to explore this architectural paradigm, two systems were built: an employee records sytem, and a vacation system.

With the widespread use of the Internet and its associated technologies, enterprises have to evolve in the way they are conducting business. 'e-business applications' refer to a new class of distributed applications that involves the Internet as a communication platform. Each e-business application supports the full automation of business processes that can span across multiple enterprises. For a given application domain that involves e-business application development, a number of design decisions that best fullfil stakeholders requirements have to be made. One important issue is the reuse of functionality which exists within legacy systems that can belong to one or more enterprises within the same domain. Most existing design approaches are inadequate in supporting the exploration of all design combinations. Moreover, there is little work on how to identify the best design decisions systematically for a given application domain. In this thesis we present a pattern-based approach that addresses the architectural design of e-business applications. We identify a number of architectural patterns whose instantiation on a given design problem correspond to different architectural design alternatives. We also identify models that enable the estimation of quality attributes for such alternatives. Then we investigate and utilise methods to select the best pattern for a given design problem. We also describe the process of generating the alternative architectures, estimating their qualities, and then ranking them with respect to any quality attribute or a combination of quality attributes. We validate this approach on a real life case study in the area of capital markets. The case study concerns realistic e-business applications that rely on existing legacy applications. The validation exercise has produced predictions which have been compared with actual design decisions that have been made. The thesis also proposes a framework for the systematic identification of architectural patterns. An additional set of architectural patterns and their impact on the case study are discussed. The main contribution of this thesis is in the identification of patterns and quality attributes models for the architectural design of e-business applications that aid in the systematic selection of the most appropriate architectural pattern for a given problem context.
