...YFOSBAPP Database A database is information organized in such a way that a computer program can quickly select pieces of data. You can think of it as an electronic filing system. A database is an organized collection of data. It is the collection of schemas, tables, queries, reports, views and other objects. Data Integration Data integration involves combining data residing in different sources and providing users with a unified view of these data. This process becomes significant in a variety of situations, which include both commercial (when two similar companies need to merge their databases) and scientific (combining research results from different bioinformatics repositories, for example) domains. Data integration appears with increasing frequency as the volume and the need to share existing data explodes. It has become the focus of extensive theoretical work, and numerous open problems remain Existing DBMSs provide various functions that allow management of a database and its data which can be classified into four main functional groups: Data definition – Creation, modification and removal of definitions that define the organization of the data. Update – Insertion, modification, and deletion of the actual data. Retrieval – Providing information in a form directly usable or for further processing by other applications. The retrieved data may be made available in a form basically the same as it is stored in the database or in a new...

Both timing constraints and data consistency should be taken into consider in real-time database systems when scheduling the transactions so that they can be accomplished by their corresponding deadlines[3]. For instance, both the query and update on the acquisition data of smart electricity meters, mainly working for the calculation of the multistep electricity price and electricity increment, must satisfy not only the database consistency constraints but also the time constrain, processed within the given deadlines. Apart from the time constraints that are out of the demand of continuously data tracking, timing correctness requirements are also proposed due to the need to keep data available for the decision-making activities of the controlling systems[4].

This is required as foundational knowledge for the chapters to come. We will explore it at a business level and a minimal technical level. | | Evolution | | The business landscape has changed over the past seventy years in every significant way. Without information systems, these changes would not have occurred. To gain a perspective on the evolution of information systems, we can review the significant computer inventions from the first computer through to cloud computing. As computer technology progressed, new skills had to be learned, and new methods of management evolved to replace old hierarchical styles with new team based methods. Increased productivity resulting in new information technology caused the downsizing of employees that began in the late 1980s and has continued. Information systems consultants identified productivity gains, so large that they cut the numbers in half and still weren't believed. Many of the products and services we use every day had not been invented just five or ten years ago. The ability to communicate electronically with anyone anywhere in the world...

...Chapter 1 Database Systems Why Databases? * At the heart of all of these systems are the collection, storage, aggregation, manipulation, dissemination, and management of data * Databases are specialized structures that allow computer-based systems to store, manage, and to retrieve data very quickly Data vs. Information * Data – raw facts * Raw indicates that the facts have not yet been processed to reveal their meaning * You transform the raw data into a data summary * Information – the result of processing raw data to reveal its meaning * Data processing can be as simple as organizing data to reveal patters or as complex as making forecasts or drawing inferences using statistical modeling * To reveal meaning, information requires context * Raw data must be properly formatted for storage, processing, and processing * Ex: dates must be stored in Julian calendar formats and yes/no responses must be converted to Y/N or 0/1 * Data are the foundation of information which is bed rocked of knowledge * Knowledge – body of information and facts about a specific subject * Knowledge implies familiarity, awareness, and understanding of information as it applies to the environment * A key characteristic of knowledge is that “new: knowledge can be derived from “old” knowledge * Key Points: * Data constitute the building blocks of information * Information is produced by processing...

...2010-05. Who’s Driving this Cloud? Towards Efficient Migration for Elastic and Autonomic Multitenant Databases Aaron Elmore Sudipto Das Divyakant Agrawal Amr El Abbadi Department of Computer Science University of California, Santa Barbara, CA, USA {aelmore, sudipto, agrawal, amr}@cs.ucsb.edu Abstract The success of cloud computing as a platform for deploying webapplications has led to a deluge of applications characterized by small data footprints but unpredictable access patterns. An autonomic and scalable multitenant database management system (DBMS) is therefore an important component of the software stack for platforms supporting these applications. Elastic load balancing is a key requirement for effective resource utilization and operational cost minimization. Efficient techniques for database migration are thus essential for elasticity in a multitenant DBMS. Our vision is a DBMS where multitenancy is viewed as virtualization in the database layer, and migration is a first class notion with the same stature as scalability, availability etc. This paper serves as the first step in this direction. We analyze the various models of database multitenancy, formalize the forms of migration, evaluate the offthe-shelf migration techniques, and identify the design space and research goals for an autonomic and elastic multitenant database.

...FILE ORGANIZATION TERMS AND CONCEPTS THE DATA HIERARCHY A computer system organizes data in a hierarchy that starts with bits and bytes and progresses to fields, records, files, and databases * A bit represents the smallest unit of data a computer can handle * A group of bits, called a byte, represents a single character, which can be a letter, a number, or another symbol (A,2?,S) * A grouping of characters into a word, a group of words, or a complete number (such as a person’s name or age) is called a field Ex: employee Last name, Customer Account number * A group of related fields, such as the student’s name, the course taken, the date, and the grade, comprises a record; Ex: There will be one record for every one * A group of records of the same type is called a file. Ex: Employee Benefits file, Employee payroll file * Database: A group of related files about a specific entity Ex: HR database PROBLEMS WITH THE TRADITIONAL FILE ENVIRONMENT In most organizations, systems tended to grow independently without a company-wide plan. Accounting, finance, manufacturing, human resources, and sales and marketing all developed their own systems and data files. Figure 6-2 illustrates the traditional approach to information processing * In the company as a whole, this process led to multiple master files created, maintained, and operated by separate divisions or departments. As this process goes on for 5 or 10 years, the organization is saddled...

...Research projectDatabase TrendssUBMITTED BYAndrew HoPatrick TchissamboFlavio baptista | | | PROFESSOR TAHEREH DANESHI | Summary page Our project is about database trends. We started the project by identifying aims and goals such as understanding what database is.We calculated in detail and understood and researched on database understood database used by ORACLE. INTRODUCTION The definition of a database is a structured collection of records or data that is stored in a computer system. In order for a database to be truly functional, it must not only store large amounts of records well, but be accessed easily. In addition, new information and changes should also be fairly easy to input. In order to have a highly efficient database system, you need to incorporate a program that manages the queries and information stored on the system. This is usually referred to as DBMS or a Database Management System. Besides these features, all databases that are created should be built with high data integrity and the ability to recover data if hardware fails. (What is a Database?, 2010) AIM The aim of the study is many folded such as, understanding database, go in detail and understand and research on database, understand the technology used by ORACLE, derive conclusions on the development in the field of database. LIMITATIONS This study is descriptive in nature and the research is done on published secondary materials. Logical conclusions are made based on our experience and...

...Database Design Paper John Hancock DBM/380 April 23, 2013 April Johnson Database Design Paper Database systems are an organized collection of data. The data is normally organized by a couple different methods; structured and unstructured. Database systems make working in a company a lot easier when an employee is looking for information. By having a database management system in the work place the employees will have improved data sharing, data security, data access and better data integration. A couple examples of databases would be Oracle, Microsoft Access and Microsoft SQL Server. Oracle’s primary function is to store and retrieve data as it is requested. Database architecture not only focuses on the design, development, implementation and maintenance of computer programs that store and organize database information for any business or company big or small. Also a database architect my use a vast array of different languages to create a database, one language is called the structured query language or SQL. When I was in the Navy at first I didn’t realize how structured all of the information was and how much information was actually kept on file. Every duty station has a database system that is used which is Oracle. This database in particular is a very great database for the Navy to use because as information is needed a service member can access the information on the Oracle database cloud at any given time. Also the service member will know that the information...
