Properties of a Feature in Code-Assets: An Exploratory Study

Software product line engineering is a paradigm for developing a family of software products from a repository of reusable assets rather than developing each individual product from scratch. In featureoriented software product line engineering, the common and the variable characteristics of the products are expressed in terms of features. Using software product line engineering approach, software products are produced en masse by means of two engineering phases: (i) Domain Engineering and, (ii) Application Engineering. At the domain engineering phase, reusable assets are developed with variation points where variant features may be bound for each of the diverse products. At the application engineering phase, individual and customized products are developed from the reusable assets. Ideally, the reusable assets should be adaptable with less effort to support additional variations (features) that were not planned beforehand in order to increase the usage context of SPL as a result of expanding markets or when a new usage context of software product line emerges. This paper presents an exploration research to investigate the properties of features, in the code-asset implemented using Object-Oriented Programming Style. In the exploration, we observed that program elements of disparate features formed unions as well as intersections that may affect modifiability of the code-assets. The implication of this research to practice is that an unstable product line and with the tendency of emerging variations should aim for techniques that limit the number of intersections between program elements of different features. Similarly, the implication of the observation to research is that there should be subsequent investigations using multiple case studies in different software domains and programming styles to improve the understanding of the findings.

Software as a service and security

Nowadays, Cloud Computing is an important hi-tech research area in the most recent innovation. These advancements give clients a few benefits: cost-adequacy, effective asset usage, cooperation, catastrophe recuperation, and elite. Cloud offers administrations for processing on a solitary mouse click. The overview was completed in the type of an online survey. This examination paper exhibits that SaaS is safer than other web applications. SaaS is superior to different applications and SaaS is savvy. This Research paper investigates the significance of SaaS for productive distributed computing for associations and its suggestions. This examination paper additionally talks about the significance of SaaS application engineering, usefulness, proficiency, benefits, and weaknesses.

Sistem Informasi Antrean Pada Pusat Layanan Kesehatan Masyarakat Dengan Electronic Kartu Tanda Penduduk Menggunakan Radio Frequency Identification

Guna mendapatkan pelayanan Kesehatan di Pusat Pelayanan Kesehatan masyarakat (Puskesmas) biasanya diawali dengan antrean, antrean merupakan aktivitas menunggu untuk dilayani oleh satu orang atau lebih guna mendapatkan pelayanan yang diinginkan. Pasien yang melakukan kunjungan Puskesmas, biasanya akan mendaftar terlebih dahulu ke loket dan kemudian diberikan nomor antrian manual dan petugas mencatat kedalam buku kunjungan dan buku tersebut sebagai rekam kunjungan sehingga setiap kali kunjungan, staf akan mencari buku pasien dan memastikan apakah pasien terdaftar atau tidak, yang menyebabkan proses pelayanan menghabiskan waktu lebih banyak. Dari permasalahan tersebut maka dilakukan penelitian untuk sistem antrean, antrean dengan memanfaatkan teknologi IoT (Internet of Things) yaitu RFID (Radio Frequency Identification) dengan obkjek e-KTP (electronic Kartu Tanda Penduduk). Pada penelitian dengan menggunakan e-KTP yang di tempelkan pada alat RFID perekaman informasi pengunjung puskesmas cukup satu kali pendataan saja dan untuk kunjungan berikutnya pengunjung tidak perlu dicatat lagi ientitasnya, pengunjung puskesmas hanya mendaftar ke bagian/ poli yang ingin didatangi, seingga dapat memudahkan petugas / staf Puskesmas. Proses identifikasi menggunakan RFID dengan objek e-KTP dapat terjadi dengan menggunakan gelombang elektromagnetik, proses identifikasi RFID membutuhkan dua perangkat yaitu tag dan reader agar dapat berfungsi dengan baik. Penelitian ini menggunakan metode Guidelines for Rapid Application Engineering (GRAPPLE) agar dapat menghasilkan luaran dari sistem ringkas namun tidak mengurangi kualitas sistem yang dibangun. Penelitian ini bertujuan untuk memudahkan pelayanan Puskesmas salah satunya pada proses antrean. Sistem Informasi Pusat Layanan Kesehatan Masyarakat Menggunakan RFID dan objek e-KTP dapat dibuat dan dioperasikan dengan mikrokontroler ESP8266 sebagai pusat kendali rangkaian dan fitur Multi Database yang memudahkan dalam sinkronisasi dengan sistem Rekam Medis, sehingga sistem informasi yang di buat dapat diimplementasikan pada Puskesmas

Smart City Solution Engineering

Many smart city applications have been proposed and demonstrated over the years; however, moving to large-scale deployment is still scarce. A contributing factor to this scarcity is the lack of well-established engineering methodologies for large-scale smart city applications. This paper addresses engineering methodologies and tools for large-scale smart city application engineering, implementation, deployment, and evolution. A model-based engineering approach based on IoT, SOA, and SysML is proposed and applied to a smart streetlight application. Engineering considerations for streetlight area enlargement and updated technology generations with additional capabilities are discussed. The proposed model-based engineering approach provides considerable scaling simplifications and opportunities for considerable savings on engineering costs. The model-based engineering approach also provides good documentation that enables technology evolution specifications that support both maintenance and emerging behaviours.
