...HANDS ON DATABASE by Steve Conger © 2010 Hands ON Database Introduction Many students taking an introductory database course need hands-on experience. Typically they are under pressure to finish quickly with a certificate or degree and get to work. They need to get actual practice in the process of designing and developing databases that they can apply in their future employment. They need to create tables, enter data, and run SQL queries. This book is designed for them. Hands on Database: an Introduction to Database Design and Development focuses on the process of creating a database. It guides the student through the initial conception of the database. It covers gathering of requirements and business rules, the logical and physical design and the testing of the database. It does this through a continuous narrative that follows a student, Sharon, as she designs and constructs a database to track the tutoring program at her school. It shows some of her missteps as well as her successes. Students get hands-on experience by doing practices and developing scenarios that parallel the narrative. After completing this book students will have a good sense of what is involved in developing and creating a database. Below is a list of the book outcomes. A student who has completed this book will be able to give a general definition of a relational database to identify a variety of ways to gather database requirements to define business rules for a database to create an...

...Forensic Science Introduction Within this paper the author will explain what DNA is, describe how it used and discuss the ethical issues surrounding the idea of having a national database. Deoxyribonucleic acid (DNA) is the hereditary material in all humans and almost all other living organisms. Nearly every cell in a person’s body has the same DNA however no two people have the same DNA make-up. Most DNA can be found in a cell nucleus. (http://ghr.nlm.nih.gov/handbook/basics/dna) DNA was first discovered in 1892 but wasn’t used in criminal investigations until a murder inquiry of two young girls between 1983 and 1986 which Professor Alec Jeffreys used DNA profiling to convict suspect Colin Pitchfork in 1988. Only one-tenth of a single percent of DNA differs from one person to the next. Scientists or forensic profilers can use this to generate a DNA profile of an individual using samples from blood, bone (marrow), hair, semen and other body fluids and tissues. Main Body In 1984 a very popular figure of the party Greenpeace Hilda Murrell was murdered in Shrewsbury. She had been stabbed, sexually abused and kidnapped before being left to die in a Shropshire wood of hypothermia along with her other injuries. She was due to give evidence at a public inquiry about a proposed nuclear reactor. Also her nephew played a crucial part in the sinking of the Belgrano during the Falklands war. This prompted a rash of conspiracy theories pointing the finger at British...

...Network 8 Application 9 Conclusion 11 References. 12 Introduction In the modern world, businesses depend largely on databases and therefore in a case whereby such databases became unavailable then it would be an indication the businesses will also fail. As a result, there are lots of different databases in the market with different characteristics in term of memory planning, processes, and physical appearance. It is the obligation of an organization to understand the features of such databases to make the correct choice regarding which one to purchase. Therefore, an outline of the comparisons between the Oracle 12c and the Microsoft SQL Server 2012 has been given. History. The Microsoft SQl Server was initially released in the year 1989, and major improvements have been done o it since then. On the hand, the Oracle database was released in the year 1980. Both databases use the c++ language to carry out their operations which in turn makes them compatible with a lot of computing devices. However, Oracle uses C language as well. Microsoft SQL is widely used in Windows operating systems while on the other hand, Oracle is used in OS X, AIX, Linux, Windows, z/OS and Solaris operating systems which clearly makes it the widely used database (Bryla & Loney, 2013) As well, the partitioning in Microsoft SQL is done by the use of tables which can be distributed over several files in a horizontal...

...http://link.springer.com/chapter/10.1007/978-3-642-01793-3_20 Eigenvalue estimation plays an important role in biometrics. However, if the number of samples is limited, estimates are significantly biased. In this article we analyse the influence of this bias on the error rates of PCA/LDA based verification systems, using both synthetic data with realistic parameters and real biometric data. Results of bias correction in the verification systems differ considerable between synthetic data and real data: while the bias is responsible for a large part of classification errors in the synthetic facial data, compensation of the bias in real facial data leads only to marginal improvements. https://www.eff.org/wp/biometrics-whos-watching-you September 14, 2003 September 2003 Introduction Among the many reactions to the September 11 tragedy has been a renewed attention to biometrics. The federal government has led the way with its new concern about border control. Other proposals include the use of biometrics with ID cards and in airports, e.g. video surveillance enhanced by facial-recognition technology. The purpose of this document is to sketch out EFF's concerns about biometrics. In today's public arena, biometric technologies are being marketed as a "silver bullet" for terrorism; however, very little independent, objective scientific testing of biometrics has been done. Deploying biometric systems without sufficient attention to their dangers makes them likely to be used in a...

...Web 407 Week 3 Database Paper In the business world, most people will find a need for a database software program to store or house data pertaining to their business. There are however, multiple things to consider before one makes their final choice on what software they will be using. A few things that should be addressed are the type of software desired, either open-source or propriety, and what characteristics of the database meets the company’s needs. There are two basic types of database programs people can choose from when deciding what they want for their small business, an open-source database or a propriety one. While both of these are similar, they still have their advantages and disadvantages. First, consider what an open-source program is. The term open-source means exactly what it sounds like; the source code for the software is completely open and free to the public. Some advantages that come with this are the fact there is no upfront costs when it comes to obtaining the database program. While this sounds great, one needs to consider the tools the business has at its disposal. If you do not have the people to manage the databases and run them, then more employees must be hired in order to support the system. This can lead to more cost in the long run. So the fact that it’s free can also be a disadvantage. Another advantage to open-source database systems is a lot of them have a huge following such as MYSQL. MYSQL is database that is designed to use Standard...

...Column or Field Depending on what type of database management system you are working with, the terms column and field are often used interchangeably. Basically, a column represents one attribute of a record in a table. As an example, think about a table containing information from your email contacts list. The entries of your contact list would contain information such as name, email address, and telephone number. Each of these pieces of information would be considered a column or field. Database A database is an organized collection of information. This information can be stored as a set of text files or spreadsheets as well as in many other forms. Even a simple hand-written address book that contains basic information such as name, address, and phone number could be considered a database. Database Management System (DBMS) A database management system, or DBMS, is a tool or software application used to create and manipulate databases. Common examples of such applications that are used on a wide-scale basis are Google Spreadsheets and Microsoft Excel. Other programs that are more widely used by database developers include MySQL, Microsoft Access, and Microsoft SQL Server. Datatype The datatype of a column is a particular data format allowed in that column. For example, suppose one of the columns of your table is designated to contain the three-letter abbreviation for each month of the year. Then, the datatype of that column would be a character string consisting of exactly three...

...Internet Databases I do support medical information electronically stored on an Internet database because the advantages out weight the disadvantages. A major benefit is if you or a family member gets into an accident, then the ambulance will have access to yours or a family member’s information. This can save your life because if you cannot remember or unresponsive, then the information will already be in the database. Maybe you are out of town on business and you go to the hospital, then the hospital staff can have access to you information (Macdonald, 2007). Having all your information in the database can help to make sure you are not given the wrong medication, which this can cause serious health problems and even death. Also, this can make it easier for the medical staff to retrieve your information as soon as possible, so you can receive the best medical care. Not have the database can lead to more deaths and medical mistakes because it can take longer for the medical staff to get your information. The disadvantages of the database would be if others were reading you information without your knowledge or consent. With having information stored on the Internet database can steer people to pay for the information, the records getting exchanged because of blackmail, or the information getting stolen. Since there are many hackers that can get into the Internet database and they can get the information to sell them to anyone. Having people reading your information...
