Web-based programming projects.
This book is the first of three volumes which provide guidance to students undertaking web-based computing projects. Developing a web-based project rather than a stand-alone application involves a particular set of challenges, but also provides new opportunities to meet the requirements of the user. Web applications often require a mixture of technologies which can work together on a single web page. In the example projects in this book, HTML, CSS, SQL, PHP, JavaScript and p5.js program code are mixed in convenient ways to achieve the required outcome. In Volume 1, a variety of business and information applications are developed. An object-oriented approach is used in the projects, with object classes forming a link between database tables and web pages. Methodologies are developed for transferring data between different web pages, and between PHP and JavaScript functions.

Gesch瓣ftsprozessoptimierung in der Softwareentwicklung. Evaluierung von Methoden zur praktischen Umsetzung
Projektarbeit aus dem Jahr 2020 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1,2, Hochschule Ravensburg-Weingarten, Veranstaltung: Projektseminar, Sprache: Deutsch, Abstract: Im Rahmen dieser Projektarbeit soll die Frage beantwortet werden, welche Methoden zur praktischen Umsetzung von Gesch瓣ftsprozessoptimierungen (Six Sigma, Lean Management, Kaizen, Agiles Prozessmanagement) in der Softwareentwicklung Anwendung finden k繹nnen. Die Hauptaufgabenstellung liegt darin, die verschiedenen Methoden auf die Softwareentwicklung zu adaptieren, zu evaluieren und miteinander zu vergleichen. Hierbei soll auch erl瓣utert werden, ob die Art des Projektes (Umfang, Thema, et cetera) die Eignung der Methoden zur Gesch瓣ftsprozessoptimierung bestimmt. Des Weiteren soll er繹rtert werden, ob es Voraussetzungen oder Einflussfaktoren gibt, die das Projektteam oder das Unternehmen mitbringen m羹ssen, um den Erfolg der Gesch瓣ftsprozessoptimierung zu sichern. Seit der industriellen Revolution wurde die Produktivit瓣t durch Arbeitsteilung massiv erh繹ht. Dabei wurden komplexe Abl瓣ufe in kleine Schritte - Funktionen - zerlegt, welche durch darauf spezialisierte Mitarbeiter effektiv durchgef羹hrt werden konnten. Doch in der zweiten H瓣lfte des 20. Jahrhunderts f羹hrte die Konzentration auf Funktionen auch zu Nachteilen f羹r die Mitarbeiter. Des Weiteren stellte sich heraus, dass durch die Arbeitsteilung die Erf羹llung von Kundenw羹nschen, insbesondere bei Dienstleistungen, erschwert wird. Zus瓣tzlich ver瓣nderten sich die Anforderungen an Unternehmen durch die Digitalisierung und Globalisierung: Produkte wurden immer komplexer, Kundenanforderungen spielten eine gr繹?ere Rolle und durch den sich schnell ver瓣ndernden Markt sind Unternehmen zu einem hohem Ma? an Flexibilit瓣t gezwungen, wenn sie wettbewerbsf瓣hig bleiben wollen.
Beurteilung der Qualit瓣t von Software. Software Benchmarking und die Entwicklung eines Plugins f羹r Sonarcube
Masterarbeit aus dem Jahr 2014 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1, Johannes Kepler Universit瓣t Linz (Institut f羹r Wirtschaftsinformatik - Software Engineering), Sprache: Deutsch, Abstract: Was ist Qualit瓣t von Software und wie kann man sie bestimmen? Beide Teile dieser Frage sind zentrales Thema dieser Arbeit. Zuerst wird versucht, eine Definition f羹r Software Qualit瓣t zu finden, bevor ein Vorgehen zur dessen Bestimmung, n瓣mlich das Software Benchmarking, vorgestellt wird. Die n瓣here Betrachtung des Benchmarkings f羹hrt anschlie?end zur Entwicklung eines Plug-Ins f羹r SonarQube, welches das Benchmarking der einzelnen Softwareprojekte erm繹glicht. Dieses Plug-In namens SBench errechnet, aufgrund der Regelverletzungen, alle vier Quartillen und ordnet die Projekte anschlie?end darin ein. Das Ergebnis wird in Form eines Boxplots und eines Benchmark Profils f羹r den Benutzer grafisch dargestellt. Die Anwendung des Plug-Ins zeigte, dass die Qualit瓣t der Projekte, im Vergleich zu den Referenzprojekten, sehr schnell eingesch瓣tzt werden konnte und sich die M繹glichkeit er繹ffnete gezielt Qualit瓣tsverbesserungen durchzuf羹hren. Das einzige Manko stellt die doch l瓣ngere Zeit in Anspruch nehmende Berechnung dar. Die Informations- und Kommunikationstechnologien haben in den letzten Jahrzehnten eine immer bedeutungsvollere Aufgabe erhalten. Mittlerweile ist eine Welt ohne Computer, Smartphones und anderen Rechner unvorstellbar. Sie sind Bestandteil des t瓣glichen Berufslebens, alle Bankgesch瓣fte werden mit ihrer Hilfe abgewickelt und in naher Zukunft wird es vermutlich m繹glich sein, ein ganzes Haus durch wenige Tastendrucke zu steuern. All diese eingesetzten Ger瓣te k繹nnten jedoch nicht die gew羹nschten Funktionalit瓣ten ausf羹hren, w羹rde auf ihnen nicht eine geeignete Software laufen. Ein St羹ck Software ist inzwischen in mehr Dingen enthalten, als man es sich jemals vorstellen konnte. Von der Waschmaschine, 羹ber Uhren bis hin zu Autos funktioniert alles nur noch
