The Information Age has emerged with speed, excitement, and great promise. The electronic eyes and ears of technology follow us everywhere. There are those enamored with the rush of technology, who b elieve that the best of worlds is one in which everyone can peer into everyone else's lives. In fact, we now live in a world consumed with "the ecstacy of communication" (Karaim 76). Americans line up to reveal their darkest secrets of their m ost intimate moments, or just "hang out their dirty laundry" on the numerous television talk shows. The more exposure, the better. So it may be absurd that we should worry that our privacy is being endangered, our personal life and even our se crets made public. The loss of privacy is on the fast track, and the high-tech Information Age is a willing conspirator. Somebody, somewhere, may know something about you that you'd prefer to keep private: how much you earn a year, what you paid for yo ur car or house, whether you've had certain diseases, what your job history is. Your medical, financial, consumer, and employment records are in computers and may be flying through cyberspace without your knowledge or consent.
Electronic progress has been miraculous, even exciting, but with it problems evolve. One of the greatest is the threat to people's personal privacy. The Automatic Teller Machine (ATM) was developed in the 1980's to give people an easier way to de posit and withdraw cash that they had in the bank. Everyone who has an account is assigned a secret PIN number, but someone in the bank has access to clients' financial records in the electronic database. Another type of new technology is the ele ctronic tolls used on the nation's highways. Drivers can pay tolls...

The personal connection Americans have with their phones, tablets, and computers; and the rising popularity of online shopping and social websites due to the massive influence the social media has on Americans, it is clear why this generation is called the Information Age, also known as Digital Age. With the Internet being a huge part of our lives, more and more personal data is being made available, because of our ever-increasing dependence and use of the Internet on our phones, tablets, and computers. Some corporations such as Google, Amazon, and Facebook; governments, and other third parties have been tracking our internet use and acquiring data in order to provide personalized services and advertisements for consumers. Many American such as Nicholas Carr who wrote the article “Tracking Is an Assault on Liberty, With Real Dangers,” Anil Dagar who wrote the article “Internet, Economy and Privacy,” and Grace Nasri who wrote the article “Why Consumers are Increasingly Willing to Trade Data for Personalization,” believe that the continuing loss of personal privacy may lead us as a society to devalue the concept of privacy and see privacy as outdated and unimportant. Privacy is dead and corporations, governments, and third parties murdered it for their personal gain not for the interest of the public as they claim. There are more disadvantages than advantages on letting corporations, governments, and third parties track and acquire data to personalized services and advertisements for us.
A database contains a variety of data which are structurally placed in order. They can easily be manipulated, accessed and viewed e.g. a dictionary, timetable or telephone book. A database is like a bank, were you either retrieving the money as well as storing it or you just simply view the amount.
The issue on privacy is extremely controversial in today’s world. As the United States’ use of the internet, a global web of interconnected computer networks, expands, so does its problem with privacy invasion. With the U.S. pushing for new laws governing internet use, citizens are finding their privacy being pulled right from underneath them. Web users are buying and selling personal information online as well as hacking users for more information. One may argue that there is no such thing as privacy on the internet, but privacy is a right among Americans, and should be treated as such.
In 1970, Edgar Codd wrote several papers outlining in theory a new approach to database construction that would use a table of records and a unique identifier called a ¡§key¡¨ to search for related records within the table. Codd demonstrated that such a system could provide sets of data in a single operation without the need for the end user navigation required by earlier flat file models. Codd¡¦s theory resulted in the introduction of relational database management systems. Relational databases organize information in multiple tables that are linked together and include built-in functions allowing them to retrieve, sort, and edit the data in numerous ways. Instead of duplicating records in each table, the data can be stored in one table and simply linked to other tables that might utilize it. In addition, data retrieval speed is increased by the ability of a relational system to access any of the linked tables with a single connection instead of requiring multiple tables to be opened for data extraction (Wise).
RDBMS remains for Relational Database Management System. RDBMS information is organized in database tables, fields, and records. Each RDBMS table comprises of database table columns. Every database table line comprises of one or more database table fields. RDBMS store the information into the accumulation of tables, which may be connected by basic fields (database table sections). RDBMS additionally give social administrators to control the information put away into the database tables. Most RDBMS use SQL as database query language
SQL is the Structured Query Language. A database and SQL help communicate with each other. Its main function is to manage data. According to sqlcourse.com, SQL are “used to perform tasks such as update data on a database, or retrieve data from a database.” The majority of all databases in someway use SQL. SQL is an effective tool for accessing and controlling databases. SQL is also an American National Standards Institute standard.
While operational databases maintain state information, data warehouses typically maintain historical information. Although there are several forms of schema, e.g., star schema and snowflake schema, in the design of a data warehouse, the fact tables and dimension tables are its essential components. Users typically view the fact tables as multidimensional data cubes. The attributes of a dimension table may be organized as one or more concept hierarchies.
Oracle's relational databases represent a new and exciting database technology and philosophy on campus. As the Oracle development projects continue to impact on University applications, more and more users will realize the power and capabilities of relational database technology.
The comprehensive tools in Microsoft Excel make it easy to create powerful spreadsheets and work with others to review and analyze them. Excel gives novice and intermediate users more confidence in working with spreadsheets by making more of the existing functionality easier to discover as well as by providing more intelligence to help assure users that they are not making mistakes. For the advanced users, Excel focuses on making common tasks easier and more intuitive. Excel is designed to make it easy for anyone to share data with others, connect to important data on the Web or within an organization, and analyze that data to make better decisions. Excel allows users to spend time analyzing their data rather than worrying about their software. For example, in the past, if an error were to occur, it was likely that the user would have had to spend a significant amount of time recreating their work.
Database systems play an important role in our daily lives, and the need to be used in various fields of life in the present day are
First, database management systems can be very complex and difficult to understand. The designers and the end users must have the necessary skills in order for them to use it properly. The database designers need to have the SQL coding knowledge to properly write the database software. Not only do they have to know SQL coding, they will have to learn the altered version of SQL the database management software might use. The end user will need the understanding of how to run queries, generate reports, and update the database if their security level allows.
Determining the tables can be the trickiest step in the database – the reports you want to print, the forms you was to use, the questions you want answered – don’t necessarily provide clues about the structure of the tables that produce them.
The transfer and preservation of Information is a major part of the digital age. People try to control their flow of information and the amount of information websites,organisations and even the government has on them. And even with the various ways of protecting information, there are still issues of privacy, freedom of information and the conflict between the public and private domains on who really owns or governs these information.
Data is raw, unorganized facts that need to be processed data can be something simple and seemingly random and useless until it is organized.
Data can be organized a specific way for each business to be able to get the best use. Employees can also access the system at the same time but in different ways. For example, the customer service team can pull up documents and keep track of complaints at the same time that the marketing team is in a
