Book Description
This work follows the ICDL (International Certification of Digital Literacy) Database Basic and Advanced Syllabus, expanded according to the document on Curriculum Guidelines for Undergraduate Degree Programs in Computer Science of December 20, 2013 by the Association for Computing Machinery and IEEE Computer Society. As for the know-how aspects (skills), some use Microsoft Access, which is not professional and has a non-standard version of SQL. This text uses MySQL and SQLite. They are professional, open source, totally free and widely used and easy to install. This satisfies the skills of the ICDL modules. However, the question of how to use this data remains. To do this today you need to master the Python language or the R language, which require learning times and delay the start of practice by weeks. There is a third possibility: using visual environments that allow you to make applications without knowing any language. Orange is one of these. It is visual but is based on Python, it allows you to make applications without knowing the language but also allows you to extend the application if and when you know Python. In addition, MySQL and SQLite coexist with Python and Orange Data Mining. This text uses Orange as an environment for experimentation and exercise in Data Science. It is possible to decide not to install Orange in case one is interested exclusively in SQL. In this case the reader will be free to skip the application exercises with Orange and return to them later if he/she feels the need. It should be clarified that this text follows the ICDL Syllabus and provides the skills associated with the modules in question, but it is not able to guarantee that the reader will be able to automatically pass the certification exam. In fact, it requires the purchase of a skill card, registration with a test center, compliance with a series of rules dictated by the national member organizations of the ICDL consortium and by the test center, and all of this is beyond what we can guarantee. After describing the installation of the programs used for the exercises, the text considers the types of data and their representations, including images and documents. The concepts of System, Information System and Database are introduced, as well as the most common practices of data security and privacy. The relational model and SQL are also explained with application examples with MySQL and SQLite. The various types of Joins, sorting, aggregation and grouping queries, integrity constraints, GRANT and REVOKE security features, views, indexing, Normal Forms and Normalization are then analyzed. Multi-user access to databases, interference and deadlock, locking techniques and transactions are then considered. Distributed databases and the possible options with MySQL and SQLite are then described. The limits of the relational model and the most common non-relational models (NOSQL) are outlined, the conceptual Entity-Relationship and object models according to ISO/UM and the process for moving from the problem text to the conceptual and logical relational model. The data integration process is outlined also with the use of data warehouses, data lakes and mediators, data cleaning, management of missing, repeated, anomalous and incorrect values, coding of categorical values. Finally, the project objectives are distinguished according to the best model, whether relational or non-relational. The text is accompanied by supporting material and it is possible to download the examples and test data.

Teaching and Learning in Digital World
Author: Mercè Gisbert
Publisher: PUBLICACIONS UNIVERSITAT ROVIRA I VIRGILI
ISBN: 8484243761
Category : Education
Languages : en
Pages : 212
Book Description
Many reports over the last few years have analysed the potential use of games, videogames, 3D environments and virtual reality for educational purposes. Numerous emerging technological devices have also appeared that will play important roles in the development of teaching and learning processes. In the context of these developments, learning rather than teaching becomes the main axis in the organisation of the educational process. This process has now gone beyond the analogue world and face-toface education to enter the digital world, where new learning environments are being produced with ever greater doses of realism. Teaching and Learning in Digital Worlds examines the teaching and learning process in 3D virtual environments from both the theoretical and practical points of view.

Nursing Informatics
Author: Marion J. Ball
Publisher: Springer Science & Business Media
ISBN: 147574160X
Category : Medical
Languages : en
Pages : 432
Book Description
Nursing, like other health-related professions, is information-inten sive. The quality of care a patient receives is based on the soundness of judgment exercised by the health care team. Underlying sound judg ment is up-to-date information. Unless nurses have access to accurate and pertinent information, the care being rendered will not be of the highest standard. What is required is not necessarily more rapid and efficient informa tion services. Modern technology can process immense amounts of data in the blink of an eye. What we in the health professions need are information systems that are more intelligent, systems that can inte grate information from many sources, systems that analyze and syn thesize information and display it so that it may be applied directly in patient care-in other words, information that answers a question or even gives practical advice. In order to accomplish such objectives, work is needed to establish the scientific and theoretical basis for the use of computing and infor mation systems by health professionals. This is the research com ponent. In addition, there is the need for continued development and evaluation of practical information systems.

Book Description
To assess progress made in the first years of Qatar's implementation of its K-12 education reform, RAND analyzed data from school-level observations, national surveys, and national student assessments. Findings reveal that the new, Independent schools had implemented many elements of the reform, that students in these schools were performing better than students in Ministry of Education schools, and that much work was still needed to enable students to meet the new, higher standards.
