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 (, 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.
