How businesses store, organize, and manage their data has a tremendous impact on organizational effectiveness (Laudon & Laudon, 2012). In order to determine whether to have a separate database from a data warehouse, you must first understand the differences between the two. A database is referred to as an organized collection of data. Databases are created to operate large quantities of information by storing, retrieving, inputting, and managing that information. Databases are set up so that one set of software programs provides all users with access to all the data. A simple database is usually designed in normalized tables in order to minimize redundancy and optimize writing operations to the table. This can be acquired by dividing large tables into smaller tables and less redundant tables, so that data of the same kind are isolated in one place so that additions, deletions, and modifications of a field can be made in just one table. The smaller tables are then connected together via defined relationships between them, resulting in many junctions between tables when retrieving the data. Data is often stored in separate systems, sometimes making it difficult to obtain certain pieces of information. In order to retrieve data from a database, one has to use a database management system (DBMS). The database management systems are designed applications that interact with the user, other applications, and the database itself to capture and analyze data. The DBMS is designed to allow the definition, creation, querying, update, and administration of databases (DifferenceBetween.info, 2014). The DBMS relieves the programmer or end user from the task of under- standing where and how the data are actually stored by separating the logical a...

...smissions. The next evolution in wireless communication, called 4G networks, is entirely packet switched and capable of 100 Mbps transmission speed, with premium quality and high security (Laudon & Laudon, 2012). Overall, convenience is the greatest advantage mobile wireless networks have over wired networks. Wireless networks are slower, less reliable, and less secure than wired networks.
A mobile wireless network works well with an educational environment like the one we are experiencing. Our colleagues are from many different parts of the states, and many of us work full time jobs at different hours of the day. A mobile wireless network allows us to communicate at real time while still performing our personal or family obligations. For myself, I am able to sign-in online through my mobile device and participate in my class assignments while on my lunch break.
Strategies that worked in a classroom from 1996, may not work for todays student in 2015. As an administrator one must be able to adapt to change. Currently, the biggest wave of change shaped by the addition of mobile technology in the classroom. With this change in education, administrators must be willing to strategize and find ways to shape instructional strategies that reflect today’s classroom climate. Naturally, most administrators have not experienced the abundance of mobile technology in the classroom during their time in class as a teen. Today’s administrator must focus and find ways to incorporate mobile technology in the instructional
As of January 2016, each teacher will use and have students use technology at least once a week in every classroom. It is important to note that the change directly aligns with district initiatives. In the early stages of implementation change, there needs to be process in place for resource allocation and addressing the barriers to change. Before full implementation of BYOD, I sat in with the logistics committee to determine what our barriers to implementing change would be and how we could collectively overcome them. For example, the issue of spotty Wi-Fi came up several times. To overcome this barrier, the team had district technology personnel come out and evaluate the connectivity. Over winter break, the district significantly upgraded the bandwidth and Wi-Fi capabilities. Another early task is having a process for resource allocation. Resource allocation includes time and funding for professional development, funding for purchase of devices for students who cannot afford their own, and purchasing of technology that will be beneficial for each
A database management system, or DBMS, gives the user access to their data and helps them transform the data into information. Such database management systems include dBase, Paradox, IMS, and Oracle. These systems allow users to create, update, and extract information from their databases. Compared to a manual filing system, the biggest advantages to a computerized database system are speed, accuracy, and accessibility.
As more and more schools are becoming wireless, all students would need to do is sign into the school’s wireless network to have free access to the Internet. Critics argue that this will lead to “distractions” and will cause “behavior and discipline issues”. Tucker, in response, points out that, in our society, mobile devices are “lifelines” and integrating them into the classroom will allow educators and administrators to teach valuable life skills that will extend far beyond the classroom walls.
A data warehouse comprised of disparate data sources enables the “single version of truth” through shared data repositories and standards and also provides access to the data that will expand frequency and depth of data analysis. Due to these reasons, data warehouse is the foundation for business intelligence.
Furthermore, there are many upsides that technology brings upon students by presenting new ways of learning where technology is being used in the classroom. Within the article “Cell phones in schools pros and cons” presented by Rujuta Borkar, the advantages of having a cellular phone device in school are through emergency contact, and having a cell phone for security purposes.
The world has gone through a lot of changed as time passes by. With advancements in the technological field people are can communicate with ones from around the world without having to even lift a finger. To make things more efficient and more cost saving industries have made technology wireless. Wireless technology gives people the chance to get up from their stationary computer, or cord phone and able to freely move without restrictions. The IT, or Information Technology has become a standard and very critical part of today’s society. Wireless technology came from the basic just cellular usage to sensors in the medical field. Wires are now a thing of the past in today’s world with forever revitalizing technology.
Major comparisons pros and cons between 3G and 4G can be summarized as follows: Architectural difference: 3G network architecture is the radio terminal base stations (BTS) aggregate the radio Access Network (RAN) traffic and transport it over a mobile backhaul network to radio network controller. The Wireless Application Protocol works on top of standard data link protocols, such as Global System for Mobile communication, code-division multiple access, and Time Division Multiple Access, and provides a complete set of network communication programs comparable to and supportive of the Internet set of protocols. Such standards are always a necessity for companies and users simply because they do not limit the opportunities to have interactive data services.
As you can see for the most part, people are connecting to wireless from the moment they leave their home till they get to work and then back. Wireless communication definitely provides an advantage over wired networks due to its mobility, allowing users to connect from virtually anywhere.
The use of cell phones in schools is one of the biggest issues being debated today since technology is growing more and more every day. Higgins discusses in his article that Datla, a sophomore says, “Using technology in everyday life is not that new to us because we grew up with technology.” The current generation has grown up using cell phones, computers, tablets, and many more devices their whole life. Some schools have installed free Wi-Fi so students can get high-speed Internet on their mobile devices, but it comes with a few rules. For example, the
Having access to a mobile device all day will create more drama among the students and the teachers. Teachers will become more frustrated because the students will not be paying attention to what they are saying. Then teachers will start to complain more and try to turn phones into the office and complain to the principle. This would probably cause the principle more stress. Also, it would also cause drama between the students bec...
Technology has rapidly changed over the years and has expanded our infrastructure greatly. In particular, as technology advances the education system adapts to the many changes. The world of technology brings about many new improvements and shows no sign of slowing down. Many people spend their day to day lives utilizing the great aspects of technology doing almost anything imaginable. Through technology teachers and students can connect and expound upon the many fields of education. Technology is an ever growing aid in education that has increased awareness, communication, and accessibility. How is technology shaping education? The uses of mobile devices and applications have shown a great influence in the education system.
Ever since incidents such as 9/11 and Columbine, high schools have started implementing new rules regarding cellphones. Cellphones attract the attention of building managers, teachers, parents, and students. Although teachers see them as a distraction and a way to cheat, they can be quite helpful to students. School districts should permit students to use cellular devices in school for purposes of improving their education and providing themselves with a sense of security. By permitting the use of cellphones in school, students can increase their knowledge and complete school work by using applications and other features on their smartphones.
There are various terms that are associated with Enterprise Data Management. Some of these terms are UML, OLAP, OLTP, Data Warehouse, Data Mart and Multi-Tier Architecture. Subsequently, these terms were covered during the five week course of DMB405 and will be explained in further detail throughout the course of the paper. Although the paper will not be all inclusive to the detail of each term, it will touch upon the definition, their use and their place in Enterprise Data Management. The first term that will be discussed is UML and how it relates to the subject at hand.
In our world, people rely heavily on the power of technology every day. Kids are learning how to operate an iPad before they can even say their first word. School assignments have become virtual, making it possible to do anywhere in the world. We can receive information from across the world in less than a second with the touch of a button. Technology is a big part of our lives, and without it life just becomes a lot harder. Just like our phones have such an importance to us in our daily lives, database management systems are the same for businesses. Without this important software, it would be almost impossible for companies to complete simple daily tasks with such ease.
