Ensuring a production-ready state of the application under development is the imminent feature of the Continuous Delivery (CD) approach. In a blockchain network, nodes communicate and store data in a distributed manner. Each node executes the same business application but operates in a distinct execution environment. The literature lacks research focusing on continuous practices for blockchain and Distributed Ledger Technology (DLT). Specifically, it lacks such works with support for both design and deployment. The author has proposed a solution that takes into account the continuous delivery of a business application to diverse deployment environments in the DLT network. As a result, two continuous delivery pipelines have been implemented using the Jenkins automation server. The first pipeline prepares a business application whereas the second one generates complete node deployment packages. As a result, the framework ensures the deployment package in the actual version of the business application with the node-specific up-to-date version of deployment configuration files. The Smart Contract Design Pattern has been used when building a business application. The modeling aspect of blockchain network installation has required using Unified Modeling Language (UML) and the UML Profile for Distributed Ledger Deployment. The refined model-to-code transformation generates deployment configurations for nodes. Both the business application and deployment configurations are stored in the GitHub repositories. For the sake of verification, tests have been conducted for the electricity consumption and supply management system designed for prosumers of renewable energy.

Delivery Approach

Ensuring a production-ready state of the application under development is the immanent feature of the continuous delivery approach. In a blockchain network, nodes communicate, storing data in a decentralized manner. Each node executes the same business application but operates in a distinct execution environment. The literature lacks research, focusing on continuous practices for blockchain and distributed ledger technology. In particular, such works with support for both software development disciplines of design and deployment. Artifacts from considered disciplines have been placed in the 1 + 5 architectural views model. The approach aims to ensure the continuous deployment of containerized blockchain distributed applications. The solution has been divided into two independent components: Delivery and deployment. They interact through Git distributed version control. Dedicated GitHub repositories should store the business application and deployment configurations for nodes. The delivery component has to ensure the deployment package in the actual version of the business application with the node-specific up-to-date version of deployment configuration files. The deployment component is responsible for providing running distributed applications in containers for all blockchain nodes. The approach uses Jenkins and Kubernetes frameworks. For the sake of verification, preliminary tests have been conducted for the Electricity Consumption and Supply Management blockchain-based system for prosumers of renewable energy.

Software Contracts

Compositional, plug-and-play-like reuse of black box components requires sophisticated techniques to specify components, especially when combined with third party components that are traded on component markets to individual customer’s business application systems. As in established engineering disciplines, like mechanical engineering or electrical engineering, formal documentation of business components that become part of contractual agreements are needed. With this initial problem, we explain the general, layered structure of software contracts for business components and show shortcomings of common specification approaches. Furthermore, we introduce a formal notation for the specification of business components that extends the Object Constraint Language (OCL) and allows for a broader use of the Unified Modeling Language (UML) with respect to the layered structure of software contracts for business components.

Mobile agents gained immense attraction as a new programming concept for implementing distributed applications. However, up to now mobile agent programming has been mainly technology driven, with a focus on the implementation of mobile agent platforms and only small programming applications. In this chapter, we present an extension of the standard UML that provides language concepts for modeling mobility both in analysis and design phases. This extended version of UML is applied to the modeling of an advanced telecommunication system.

One important aspect of product lifecycle management (PLM) is the computer-sensible representation of product information. Over the past fifteen years or so, several languages and technologies have emerged that vary in their emphasis and applicability for such usage. ISO 10303, informally known as the Standard for the Exchange of Product Model Data (STEP), contains the high-quality product information models needed for electronic business solutions based on the Extensible Markup Language (XML). However, traditional STEP-based model information is represented using languages that are unfamiliar to most application developers. This paper discusses efforts underway to make STEP information models available in universal formats familiar to most business application developers: specifically XML and the Unified Modeling Language™ (UML®). We also present a vision and roadmap for future STEP integration with XML and UML to enable enhanced PLM interoperability.

One important aspect of product lifecycle management (PLM) is the computer-sensible representation of product information. Over the past 15 years or so, several languages and technologies have emerged that vary in their emphasis and applicability for such usage. ISO 10303, informally known as the Standard for the Exchange of Product Model Data (STEP), contains the high-quality product information models needed for electronic business solutions. By using STEP, the aerospace, automotive, and shipbuilding industries are saving $150M/yr primarily in areas related to geometric modeling. However, traditional STEP-based model information is represented using languages that are unfamiliar to most application developers, thus impeding widespread usage in other areas. This paper discusses efforts underway to make STEP information models available via mechanisms familiar to more business application developers, specifically XML and the Unified Modeling Language™ (UML®). We also present a vision and roadmap for STEP integration with XML, UML, and other technologies to enable enhanced PLM interoperability. Our conclusion is that STEP, XML, and UML are complementary technologies, where STEP provides significant standardized content models, while XML and UML provide enhanced implementation methods. Together, they are a powerful force to enable pervasive digital representation and sharing of diverse technical information.

Monitoring of warehouse inventory data processing is an important thing for companies. PT Talaga mulya indah is still manual using paper media, causing problems that have an effect on existing information, namely: problems with data processing of incoming and outgoing goods. And the difference between data on the amount of stock of goods available with physical data, often occurs inputting data more than once for the same item, searching for available data, and making reports so that it impedes companies in monitoring inventory of existing stock of goods. Which aims to create a system that can provide updated information to facilitate the warehouse admin in making inventory reports, and reduce errors in input by means of integrated control. In this study, the authors used the data collection method used in this analysis using the method of observation, interviews, and literature review (literature study). For analysis using the PIECES analysis method. Furthermore, the system design used is UML (Unified Modeling Language). The results of this study are expected to produce the right data in the process of monitoring inventory data processing, also can provide the right information and make it easier to control the overall availability of goods.
