This document discusses database system concepts and architecture. It covers topics such as data models and their categories, schemas and instances, the three-schema architecture, data independence, DBMS languages and interfaces, and centralized and client-server architectures. The three-schema architecture defines three levels of schemas - internal, conceptual, and external - to support program-data independence and multiple views of the data. Data independence allows changes to lower-level schemas without affecting higher-level schemas and applications. A variety of DBMS languages exist, including DDL for schema definition and DML for data manipulation.
Database concepts and Archeticture Ch2 with in class ActivitiesZainab Almugbel
This is the slides of chapter 2 of the book Ramez Elmasri and Shamkant Navathe, "Fundamentals of Database Systems" 6th Edition, 2010
I did not include the activities in the slides. I printed them out in separate papers. Then, I asked students: who liked to participate in activity 1 (the interview) in the class. I selected 2 students for the first activity (one was the interviewer and another was the guest). I did the same for the other activities.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
