The library databases include JSTOR, ProQuest and EBSCOhost Databases. These databases require the user to create a personal account. With these three databases once the users personal account is verified, they will receive an automated email confirming the account and provide immediate access. The benefit of securing a personal account with these databases consist of the ability to organize resources, to retrieve the search history, and establish numerous alerts (Personal Database Accounts, 2015). However, the disadvantages to having a personal account with these databases, is that the user must login each session, if they want to access or save articles, and ProQuest requires the user to log in every 76 days, if not the account will become inactive after 90 days (Personal Database Accounts, 2015).

A relational database is designed to comply with a term called normalization. Normalization is a process of organizing tables to minimize the redundancy in the database. The design of a relational database decreases the amount of space the database uses in a system. The relational database uses fields to help reduce redundancy in the tables. Relational designed database use the relational value in fields, an example would be a field for Book_ISBN and a field with Title_ISBN, could be limited to just one field naming the ISBN (Safari).

To add attributes to your entity, simply click on the columns section of the database properties window, and enter in your column names. Be sure to include the appropriate attribute descriptors [rucdm] with the physical name. Ignore the data type Req’d and PK columns. Those are used in logical modeling.

1) Accurately describe the source contents. Be as specific as possible. The September 11, 2001, Documentary Project is a collection of reactions, eyewitness accounts, and opinions expressed by Americans and others in the months following the September 11 terrorist attacks on the World Trade Center, the Pentagon, and United Airlines Flight 93. The collection is comprised of 200 audio and video interviews, 45 graphic items such as photos and drawings, and 21 written narratives. 2) What things make this document significant and worthy of someone else's attention? Tell us everything you can think of that makes this document important. The September 11, 2001, Documentary Project is important because it illustrates the political climate that led the nation into a war against a nation-less enemy, which had been termed the "War on Terror." The reactions demonstrate the feeling of deep fear and insecurity prevailing amongst many Americans, who were not accustomed to seeing foreign threats on American soil. 3) Who is the audience(s)? What goal(s) was the author seeking to accomplish? What were his/her major points? What didn't the author say that might have been included? Being a collection gathered by the National Library of Congress, the intended audience is the general American public. It was gathered in order to create a record of American public opinion at the time of the September 11 attacks. 4) Place the source into its

In today’s world, we have a huge database that we all refer to as the internet. So many things can be found on the internet such as how to walk your dog or how to fix your broken TV. There are several networks on the internet that many teenagers use to communicate with each other or to simply talk about their day. These networks are known as social media networks, like Twitter, Facebook, Instagram, etc. On many of these social media networks, there are many issues involving the privacy of their users. Occasionally, users may find that someone has hacked their account and is posting false information or that somebody is trying to “catfish” them. The term catfish can be defined as a person who uses someone else’s identity, or creates their

While designing and defining tables in databases, it is important to find out the data type for each column in the data tables. A data type is an attribute which defines the type of data an object can retain: integer, string, data and time, etc. There are basically three main types: text, numbers and date/times. The data types are different, depending on the database management system (DBMS), the various types of which include SQL Server, Oracle and MySQL.

Introduction: A company called Ian’s & Co currently employs a team of IT technicians to manage their IT infrastructure and also support the IT users. Also quite recently the company has taken over a similar but a smaller company which is also employs technical support staff in the same way.

In the two scenarios there are many ways that they can be solved or worked out to make them fit to the person working with them. They both deal with databases and communications that companies need to consider. In this paper we are going to discuss some of the options that companies or self employed business owners can use.

“We create as much information in two days now as we did from the dawn of man through 2003”- Eric Schmidt, former CEO, Google Inc.

The term database was popularized with the growth of the computer industry and is typically thought of as software used to store, index, manipulate, and retrieve information (Vaughn). Database software has been in use since the Census Bureau used a punch card system to meet the requirements for the collection, sorting, and reporting of data for the 1890 census (National Research Council). These earliest databases were flat file databases. The flat-file style of database works well for small amounts of data that need to be organized to be read and edited by hand. Flat file databases are made up of tables that store a set number of characters in each field. The individual tables are

The first thing you need to do is make a list of items you need to store information about. These are called Entities or Relations (or Classes in OOAD)

Recent research on interpolation of climatological and meteorological information with the support of Geographic Information Systems (GIS) has shown that interpolation has a large development potential within climatology and meteorology. At the same time the demand for interpolated data products are increasing, numerical weather models are working at higher spatial resolutions and may be initiated by gridded data from observations. Interpolation is a method of getting new data from some known data points. In India, many weather data is from official departments and there are many weather sites, but in some areas it is difficult to obtain weather data, so we will use interpolation methods to get climate data of that areas. Interpolation can be defined as the estimation of an unknown value of the variable, at some point where no measurement is available, where the estimate is made using known measurements obtained at a set of sample locations. With the advent of Geographic Information Systems (GIS), numerous spatial interpolation methods have been applied to create continuous surfaces of climate variables at various spatial (watershed, regional, and global) and temporal (hourly, daily, monthly, seasonal, and annual) scales. The prediction of weather condition is essential for various applications. Like weather prediction, soil moisture, climate data monitoring, rainfall, population prediction, agriculture, image processing etc. Regression model, Feed Forward
