LEARNING OBJECTIVES
After studying this chapter, you should be able to:
1. Explain the importance and advantages of databases, as well as the difference between database systems and file-based legacy systems.
2. Explain database systems, including logical and physical views, schemas,
the data dictionary, and DBMS languages.
3. Describe what a relational database is, how it organizes data, and how to
create a set of well-structured relational database tables.
Relational databases underlie most modern integrated AISs. This chapter and Chapters 17
through 19 explain how to participate in the design and implementation of a database. This
chapter defines a database, with the emphasis on understanding the relational database structure. Chapter 17 introduces two tools used to design databases—entity-relationship diagramming and REA data modeling—and demonstrates how to use them to b uild a data model.
To appreciate the power of databases, it is important to understand how data are stored in
computer systems. Figure 4-1 shows a data hierarchy. Information about the attributes of a
customer, such as name and address, are stored in fields. All the fields containing data about
one entity (e.g., one customer) form a record. A set of related records, such as all customer
records, forms a file (e.g., the customer file). A set of interrelated, centrally coordinated data
files that are stored with as little data redundancy as possible forms a database. A database
consolidates records previously stored in separate files into a common pool and serves a variety of users and data processing applications.
Databases were developed to address the proliferation of master files. For many years, companies created new files and programs each time a need for information arose. Bank of America
once had 36 million customer accounts in 23 separate systems. This proliferation created problems such as storing the same data in two or more master files, as shown in Figure 4-2. This made
it difficult to integrate and update data and to obtain an organization-wide view of data. It also created problems because the data in the different files were inconsistent. For example, a customer’s
address may have been correctly updated in the shipping master file but not the billing master file.
Figure 4-2 illustrates the differences between file-oriented systems and database systems.
In the database approach, data is an organizational resource that is used by and managed for
the entire organization, not just the originating department. A database management system
(DBMS) is the program that manages and controls the data and the interfaces between the
data and the application programs that use the data stored in the database. The database, the
DBMS, and the application programs that access the database through the DBMS are referred
to as the database system. The database administrator (DBA) is responsible for coordinating, controlling, and managing the database.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

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.
