Comparative analysis of connection performance with databases via JDBC interface and ORM programming frameworks

The research subject of this paper was the comparative analysis of efficiency of connections with databases using different communication methods based on Java programming language. The tools investigated included JDBC drivers and Object-relational mapping (ORM) frameworks. A survey based on 8 different criteria was conducted to determine the most effective method and tool for working with relational databases when developing Java applications. The weights of the criteria were determined through a survey of Java programmers and computer science students.

ALEA – Adaptive eLEArning System – Lernende datenbankbasierte Lernsysteme in der Datenbanklehre

ZusammenfassungIm Bereich Datenbanken werden selbstentwickelte E‑Learning-Systeme an vielen Hochschulen seit Jahren erfolgreich verwendet. An der Hochschule Harz werden E‑Learning-Systeme im Bereich Datenbanken im Rahmen der Lehre und für die Lehre entwickelt, weiterentwickelt und eingesetzt. Das Gesamtsystem, welches die zusammengehörenden Systeme umfasst, wird als ALEA bezeichnet. Es werden relevante Komponenten von ALEA erläutert, die im Rahmen der Datenbanklehre für die klassischen Teilgebiete SQL, ER-to-Relational-Mapping und Normalisierung genutzt werden.

DESIGN AND IMPLEMENTATION OF PERSONNEL MANAGEMENT INFORMATION SYSTEM BASED ON SSM

Personnel management is a series of management activities for the company to select, use, train, evaluate, reward and punish its employees. The personnel management information system designed and implemented in this paper integrates the functions of batch import of information, instant update of personnel information, position transfer, information inquiry and statistical analysis. This system is oriented to various users such as managers at all levels of small and medium-sized enterprises and institutions. In this paper, using the aspect-oriented programming, Inversion of Control features of the Spring framework, using spring MVC model and using the ORM (Object Relational Mapping, Object Relational Mapping) feature of MyBatis, using B/S architecture and MySQL database, with high scalability, high refactorability as the design goal, designs and implements an Personnel Management Information System. The system builds a personnel database covering more than 20 information about personnel's basic information, education background, and positions, and realizes functions such as batch import of information, instant update of personnel information, job transfer, entry management, resignation management, information inquiry and statistical analysis. At the same time, it is ensured that these functions will not be illegally operated by users without authority, so that the system has higher security. This system provides an integrated solution for the informatization of personnel management and has high practical and commercial value.

Utilising Field Theory to Examine Mega-Event Led Development

Scholars and practitioners have long been analysing and evaluating the way events, particularly mega-events, serve as a mechanism of change. Powerful descriptions are typically brought to life via event impact and legacy case studies: yet, I argue such work can remain a-theoretical – or – conceptually disorganised. I draw on Bourdieu’s field theory and the management study of Field Configuring Events to develop a new analytical framework: the ‘Cognitive and Relational Mapping of Field Configuring Events’ – offering a set of inter-related concepts to strengthen analysis and conceptual consistency between studies, whilst providing latitude to overlay different disciplinary perspectives. I detail methodological and conceptual advantages afforded alongside six ways the framework could be applied-and-extended across various cases and contexts.
