Initially, with the emergence of computers and the means for mass digital storage, we started collecting and saving all sorts of data, counting on the power of computers to help sort through this mix of information. Unfortunately, these huge collections of data stored on structures that are not similar, very quickly became too much. The production of data is expanding at an incredible rate. Expert now point to a 4300% increase in annual data generation by 2020. In 2007 the estimated information content of all human knowledge was 295 exabyte, CSC predicted that in 2020 data production will be 44 times more greater than it was in 2009. …show more content…
The efficient database management systems have been very crucial assets for management of a huge amount of data, especially for effective and efficient retrieval of particular information from a large collection whenever needed. The wide spread of database management systems has also influenced the recent massive gathering of all sorts of information. Today, we have far more information than we can handle, from business transactions and scientific data, to satellite pictures, text reports and military intelligence. Information retrieval is not enough anymore for decision-making. Faced with huge collections of data, we have now created new needs to help us make better managerial choices. As we make a shift from collecting to connecting data, businesses are searching for relationships between data sets to reveal valuable new insight.

These attributes allow a system to not only function in a specific way but they also add definition to the system which in turn creates a specific identity. One of the identities of a Network is a Client/Server Network. The term "client server" defines a network system where computers known as servers are used. The Servers create central management.

Since there are a variety of Network configurations, the end user has to determine which one of the specific Network features they want and also to consider the advantages and disadvantages of each system. Even though the Client/ Network architecture is the most desirable for most commercial businesses, there are certain disadvantages in this system. “The reason that client/server computing is still growing in popularity is because top management believes that it will save them money, and end-users believe that it will solve many of their computing problems.” (Windsor, 2011) Client/Server Definition: This type of computing provides the necessary comingling of personal......

During the holidays and high volume periods, sales personnel can be strategically placed throughout the store with these mobile devices.

Logical and Physical Security

...CONVERGENCE OF LOGICAL AND PHYSICAL SECURITY SYSTEMS INTRODUCTION Up to now, majority of organizations have their physical and logical access systems operating as independent structures, with each being run by a totally separate department. The information technology security system, which controls access to information technology infrastructure including mail servers, the internet, database applications and web servers was managed by the department of information technology. The physical security system, which incorporates door access into buildings, systems of life support such as CCTV and Fire, and the badging process of employees, was run by the department of facilities (Mehdizadeh, Y, 2003). Currently, security operations involve the guarding of buildings and equipment in addition to protection of networks, taking care of issues of privacy, and risk management. The interrelation between the aspects of the security initiatives necessitates consolidation of the two security systems. Such a convergence of the IT and physical security functions is important in achieving an efficient security system (Mehdizadeh, Y, 2003). However, such an operation is also lined up with disadvantages. This paper looks at the pros and cons of combining the IT and physical security functions in a medium to large-size firm with complex IT system requirements and a global footprint. It also analyzes the fundamental components of an IT security system and explains how their integration......
