Grid computing is a method of distributed computing. It includes location and organization, software and hardware to provide unlimited power. Its name is to make anyone
DISTRIBUTED DATABASES AND DISTRIBUTED DATABASE MANAGEMENT SYSTEMS 1. INTRODUCTION Distributed database systems (SBDD) are two approaches to meeting the data processing which may seem diametrically opposed: technology systems and the database of computer networks. Database systems have evolved from data processing in which each application to define and maintain their own data, to one in which the data are defined and managed centrally. This new orientation leads to independent data, such applications become immune to changes in physical or logical data organization and vice versa. A major motivation in using database systems is the integration of data and provide a centralized and controlled access to data.
Individuals can also benefit from cloud computing, but some of the most sophisticated and advanced cloud computing services are aimed at enterprises. For example, big businesses and even smaller operations use specific cloud computing services to make different processes like supply-chain management, inventory handling, customer relationships and even production more efficient. An emerging picture of the difference between cloud computing and mobile computing involves the emergence of smart phone and tablets operating systems and, on the cloud end, new networking services that may serve these and other
Servers allow information to be stored remotely and accessed by various other computers. Servers are an integral part of businesses, especially internet businesses as there servers are being used to store data that can be accessed via the internet. They can also be used for internal intranets that allow different types of computers to share certain information internally. Companies use geographically dispersed servers, which can be used through cloud computing. Cloud computing is a process in which a computer assesses data and software that can be stored on remote servers, this type of process is used by companies such as Apple.
Also, it was seen that there was dispersion of software applications of different origins with inevitable difficulties of construction and management of interfaces between these applications. ERP Systems: Literature Review Organizations aim to use information in the best possible way so as to maximize productivity. This has lead to, the problems of integration of information systems to be one of the most discussed topic in the recent years. This is mainly because they are several isolated tools in various environments leading to duplication of information and thereby different results. The main problem of fragmented information is difficulty in finding consolidated information in one place.
CONCLUSION In this paper, we have analyzed about Cloud Computing characteristics, limitations and comparisons of cloud computing and fog computing that is probable reason for the birth of fog computing. Fog computing has the ability to handle the data tsunami created by Internet of Things. The characteristics of fog computing like mobility, proximity to end-users, low latency, location awareness, heterogeneity and due to its real-time applications fog computing platform is considered as the appropriate platform for Internet of Things. Fog Computing is not a replacement for Cloud Computing. Fog computing resolves problems related to congestion and latency.
Every organization has a different usage of electronic resources also in academic institutions. According to (Kinengyere, 2007) examined the effect information literacy (IL) has had on the usage of electronic information sources (EIS) in academic and research institution in Uganda. It focus on the innovations that any library users were trained well on how to access information sources, evaluate the information and apply it for their own needs. Solution For the solution, users now can use computer and access for accurate information because of the training program and workshops is effective. A computers literate user is expected for accessing the information from use online services and feels confident to browse the world wide web.
In an organization, there must has a main application system used to manage the entire organization daily transaction and used for accounting, financing, reporting and etc. Computer operation involve starting the program, managing output devices like printer, observing the information processing facility for unauthorized entry, backup and restore, and routine health checkup of the printer, scanner, servers, router and firewall, etc. All these operation could be undertaken centrally or at distributed locations, depending on the application and organization architecture. For the centralized operation, the operation cost would be comparatively less due to economies of scale. It is convenient and easy to manage because all the troubleshooting it can be done centrally.
