A Model-Driven Method for Fast Building Consistent Web Services from OpenAPI-Compatible Models

This conceptual study tackles the digital-adoption gap in Jakarta's kos-kosan boarding-house rooms, where landlords managing 5–20 units still juggle paper ledgers despite near-universal smartphone and WhatsApp use. Guided by the Technology Acceptance Model (TAM), Lean Start-up logic, and the Business Model Canvas (BMC), this research develops an integrated theoretical framework that explains behavioral hesitancy, sequences low-risk Minimum Viable Product (MVP) iterations, and pinpoints the "missing-middle" niche for a boarding house management platform. The proposed framework positions TAM to surface core drivers (perceived usefulness and ease of use) recast for WhatsApp-first workflows. Lean Start-up methodology will then map these insights into quick, feedback-rich MVP cycles tuned to resource-constrained settings. BMC will situate the validated feature set in a defendable market position underserved by premium PropTech and ultra-basic bots. This conceptual foundation establishes the theoretical groundwork for future empirical phases, which will combine stakeholder interviews and platform benchmarking to diagnose pain points, quantify adoption triggers, and refine the MVP and business model through qualitative fieldwork and pilot deployments. By linking behavior, experimentation, and strategy, this study lays a theory-driven pathway toward inclusive digital transformation in informal housing in emerging economies, with empirical validation planned for subsequent research phases.

In the competitive landscape of startups, achieving product-market fit is essential for survival and growth. This article introduces an expanded framework called “Product-Content-Market Fit” (PCMF), which integrates content strategy into the Minimum Viable Product (MVP) development process. Through case studies and existing literature, this study illustrates how strategic content creation aligns with customer needs and market demands, enhancing the effectiveness of MVPs. The research emphasizes the importance of a content strategy in the early stages of product development and its impact on market engagement and product validation.

The conventional product development process employs a design-build-break philosophy. The sequentially executed product development process often results in a prolonged lead-time and an elevated product cost. The proposed concurrent design and manu facturing (CDM) paradigm employs physics-based computational methods together with computer graphics techniques for product de sign. This proposed approach employs Virtual Prototyping (VP) technology to support a cross-functional team in analyzing product per formance, reliability, and manufacturing cost early in the product development stage; and in conducting quantitative trade-off for design decision making. Physical prototypes of the product design are then produced using Rapid Prototyping (RP) technique primarily for de sign verification purposes. The proposed CDM approach holds potential for shortening the overall product development cycle, improving product quality, and reducing product cost. A software tool environment that supports CDM for mechanical systems is being built at the Concurrent Design and Manufacturing Research Laboratory (http://cdm.ou.edu) at the University of Oklahoma. A snapshot of the envi ronment is illustrated using a two-stroke engine example. This paper presents three unique concepts and methods for product develop ment : (1) bringing product performance, quality, and manufacturing cost together in early design stage for design considerations, (2) supporting design decision-making through a quantitative approach, and (3) incorporating rapid prototyping for design verification through physical prototypes.

Web service architectures have gained popularity in recent years within the scientific grid research community. One reason for this is that web services allow software and services from various organizations to be combined easily to provide integrated and distributed applications. However, most applications developed and used by scientific communities are not web-service-oriented, and there is a growing need to integrate them into grid applications based on service-oriented architectures. In this paper, we describe a framework that allows scientists to provide a web service interface to their existing applications as web services without having to write extra code or modify their applications in any way. In addition, application providers do not need to be experts in web services standards, such as Web Services Description Language, Web Services Addressing, Web Services Security, or secure authorization, because the framework automatically generates these details. The framework also enables users to discover these application services, interact with them, and compose scientific workflows from the convenience of a grid portal.

In the Web Service world, it is an important technique that taking the usable behaviors in the existed web services provides some value-added functions by the service composition. Therefore, the usability analysis of web service behaviors is a significant problem to be solved. Based on our early study about behavior derivation for software components by interface automata (IA), a method is given for checking whether there are usable behaviors in a web service or not according to a user's requirement. A behavior is usable if it can be preserved in a composite web service under some constraints, otherwise it is unusable. Web services are described by BPEL4WS and the user's requirements are specified by MSCs. The key step in our proposal is to build an IA model for the web service behaviors. Thus, we give the transformation rules from BPEL4WS to IA. By using the algorithm of constructing an environment for an IA which had been given in our early works, the usability of a web service behaviors is checked. A case study from real application is used to validate our proposal.

In the era of Covid-19, people are more sensitive to their health and hygiene. SAC is present in the community as a service to clean each customer’s favourite shoes. Even though SAC has been around since 2013, until now they have not touched the digital realm. For this reason, innovation for SAC needs to be implemented so they are not left behind by competitors who are starting to become aware of digitalization. So that the implementation of digitalization can save costs and time, the approach to making digital products is through product development. To innovate through the use of product development in digital, a User-Centered Design (UCD) method approach with a Design Thinking (DT) mindset is used. The UCD process includes understanding context, specify user requirements, design solution, and evaluate. With the DT mindset, the process of emphatizing, defining, and ideation is applied to the understand context and specify user requirements so that this research will understand the usability side for users. With the addition of 5 UCD elements from Jesse James Garret, the digitalization process will be more in-depth and detailed in terms of creating interface design solutions. Primary data will be collected through In-depth Interview resulting abundant data that create persona and Minimum Viable Product(MVP). This research aims to analyze and identify the user experience flow for the prototype mobile web app product design SAC with the identifying the MVP and design prototype mobile website application and later do some usability testing to getting result that can meet the needs and uses for SAC customers. The result of this design approach method is a high-fidelity mobile web app prototype which was evaluated using Usability Testing (UT). The persona of each customer and the desire are the first key in development. Strong framework is formed with information architecture, low-fidelity, and high-fidelity prototypes. The final stage of the UCD iteration is to evaluate Usability Testing with a binary task success rate of 90%. Another UT results of quantitative data analysis with the Single Ease Question (SEQ) showed the number 6.42 and the System Usability Scale (SUS) showed the number 87.5 with quality A.

Chapter 9 - Risks and Issues: Preparing for and Responding to the Unexpected

This paper examines the intersection of entrepreneurship, innovation, and sustainability in the tourism sector through the lens of knowledge creation and transfer. It focuses on the Tourism Creative Factory (TCF) ideation programme, developed under Turismo de Portugal’s Fostering Innovation in Tourism 2.0 initiative. Using a case study methodology, the research situates the 2021–2022 “RESTART” edition of TCF within broader theoretical frameworks of knowledge-based development and organisational learning. This study highlights the programme’s role in facilitating knowledge exchange among participants, mentors, and institutional actors, thereby enhancing entrepreneurial readiness and resilience in a post-pandemic context. Emphasis is placed on mentorship, capacity-building, and experiential learning as mechanisms for knowledge management, enabling the 39 selected participants to develop sustainable business models and Minimum Viable Products (MVPs), with the 16 most innovative being selected for a final pitch presentation to a panel of experts representing diverse sectors of the entrepreneurial ecosystem. The findings underscore the transferability of TCF’s methodology to other knowledge-intensive sectors and contribute to advancing theoretical and practical understanding of how structured ideation programmes function as knowledge systems within tourism and beyond.

The Internet is going through several major changes. It has become a vehicle of Web services rather than just a repository of information. Web Services are heterogeneously developed software components invoked over the network viz. the Internet, Web Services are the most famous implementation of service-oriented architectures (SOA) that has brought some challenging research issues related to security, Quality of service. Among all the challenges Web Service Composition turns out to be a major research, because it supports business-business enterprise application integration. Web services Maneuvering is the ability to create a new value-added service by integrating related Web services together. After Composing the Web Services, Only limited number verification techniques are available. The Correctness properties of the composed service will be effective if Muller Automata and Buchi Automata is used, because these automata are suitable both for deterministic and non-deterministic system. In this paper we have taken a survey report for verification of web service maneuvering, existing techniques are suitable only for deterministic system rather than non-deterministic system

When developing modern distributed computer systems that work with DBMS data, a service-oriented architecture is widely used. For the practical implementation of such systems, Web services are used, which are developed using various technologies.At the same time, the performance of a Web service largely determines the possibility of its use in a distributed system.PHP tools provide an efficient platform for building Web services that support various technologies.PostgreSQL is one of the most common and productive DBMS. The performance of XML-RPC, SOAP and RESTful PHP Web services when searching PostgreSQL data, i.e. when performing a CRUD read operation, has been explored before.At that time, similar studies for XML-RPC, SOAP and RESTful PHP Web services in the implementation of CRUD oper-ations to create, update and delete PostgreSQL data were not made.In this work, PHP CRUD Web services were developed to work with PostgreSQL data in the amount of 1 MB, as well as a tester program that evaluates their performance based on determining the response time when making Web requests.With the help of the created programs, the analysis of performance of XML-RPC, SOAP and RESTfulPHP CRUD Web services at work with PostgreSQL data is carried out.The SOAP Web service had the highest response time when performing create, read, update, and delete operations on DBMS data, the XML-RPC service had the average, and the RESTful service had the lowest (best performance).The results obtained indicate both the significant impact of service development technology on its performance, and the advisability of using RESTful Web services when creating applications with a service-oriented architecture for working with PostgreSQL DBMS data using CRUD operations.

Web services and service-oriented architecture are emerging technologies that are changing the way we develop and use computer software. Due to the standardization of Web services related description languages and protocols, as well as the open platforms, for the same Web service specification, many different implementations can be offered from different service providers. This paper presents an adaptive group testing technique that can test large number Web services simultaneously and effectively. Based on a case study, experiments are performed to validate the correctness and effectiveness of the technique.

The growing scale and complexity of the enterprise computing systems under distributed and heterogeneous environments present new challenges to system development, integration, and maintenance. In this paper, we present a model driven web service development framework to combat these challenges. The framework capitalizes on the UML profile for Enterprise Distributed Object Computing (EDOC), MDA and Web Services. Within the framework, first, the platform independent models (PIMs) are created using the EDOC profile. Second, the PIMs are broken down into sub PIMs according to functional decomposition, each of which can provide service independently and will be implemented in a web service. Then, these sub PIMs are transformed into the corresponding web service interface models for service publication and invoking. Finally, supported by model transform techniques, the sub PIMs are implemented into web services on specific platforms. Automatic model transformation is the key to this framework, therefore, the transformation from EDOC models to Web Service interface models within this framework is deeply discussed, and the detailed transformation rules are proposed. A case study is also provided to demonstrate the effectiveness of these rules and the merits of this framework.
