...1. (a) What is the difference between an intranet and an extranet Intranet is an internal network. It is used by companies to connect their computers on a network. In general, intranet as a network based on TCP/IP protocols belonging to an organization and only the members of the organization can access the network. However, intranet is inaccessible from the outside. Only the members of the corporation with authorized access the network. Like other networks, the Intranet is mainly used to share data, information, resources, company programs, software applications. Intranet improves the data sharing capability and overall knowledge base of the company’s employees (Difference between Intranet and Extranet). Extranet, is an internal network that can be accessed externally. The extranet is the extension of the company’s intranet where People from outside the company can have a limited access to the company’s internal network for business related purposes. This access is usually granted to the organization’s partners, vendors and potential customers etc (Difference between Intranet and Extranet). Security-wise, Intranets are a lot more secure due to the limited interface with the Internet. Extranets are made less secure not only by the use of the Internet as a medium but also by the fact that the administrators of the Intranet have no control over the networks that connect to the Extranet. When sensitive information is being transmitted on the Intranet, all parties need to take...

...MANAGEMENTapplied Research projectDatabase TrendssUBMITTED BYAndrew HoPatrick TchissamboFlavio baptista | | | PROFESSOR TAHEREH DANESHI | Summary page Our project is about database trends. We started the project by identifying aims and goals such as understanding what database is.We calculated in detail and understood and researched on database understood database used by ORACLE. INTRODUCTION The definition of a database is a structured collection of records or data that is stored in a computer system. In order for a database to be truly functional, it must not only store large amounts of records well, but be accessed easily. In addition, new information and changes should also be fairly easy to input. In order to have a highly efficient database system, you need to incorporate a program that manages the queries and information stored on the system. This is usually referred to as DBMS or a Database Management System. Besides these features, all databases that are created should be built with high data integrity and the ability to recover data if hardware fails. (What is a Database?, 2010) AIM The aim of the study is many folded such as, understanding database, go in detail and understand and research on database, understand the technology used by ORACLE, derive conclusions on the development in the field of database. LIMITATIONS This study is descriptive in nature and the research is done on published secondary materials. Logical conclusions are made based on...

It is maintained and considered an integral part of most organizations worldwide. The database management system houses a program that enables storage, modification, and extraction of information from a database. In this paper team A will address database the phases of the database life cycle, and provide a conceptual representation for a database system. Team A focused on relational data model utilizing the Oracle database management system. Implementation of a Database System The purpose of the implementation phase is to make the new system available to a prepared set of users. In this phase the construction and installation of the new database system is initiated according to the plan and design that represents all aspects of the organization, including its interactions with the external environment, this requires matching the design requirements with the best available implementing tools and then using those tools for the implementation. There are several basic steps to implementation of a database system.

...Introduction This paper will address data systems; a database is an organized group of files that are related. It is maintained and considered an integral part of most organizations worldwide. In Data Base Management, programs enable you to store, modify, and extract information from a database. In this paper team A will address database types, demonstrate a conceptual representation for a database system. We focused on relational data model to explain how DBMS organizes information in different formats and design models.

...AIS Colloquium and at the 1995 Workshop on Semantic Modeling of Accounting Phenomena. Financial support was received from Arthur Andersen LLP and from the Departments of Accounting at Grand Valley State University and Michigan State University. The REA Accounting Model: Intellectual Heritage and Prospects for Progress ABSTRACT: Researchers often equate database accounting models in general and the Resources-Events-Agents (REA) accounting model in particular with events accounting as proposed by Sorter (1969). In fact, REA accounting, database accounting, and events accounting are very different. Because REA accounting has become a popular topic in AIS research, it is important to agree on exactly what is meant by certain ideas, both in concept and in historical origin. This article clarifies the intellectual heritage of the REA accounting model and highlights the differences between the terms events accounting, database accounting, semantically-modeled accounting, and REA accounting. It also discusses potentially productive directions for AIS research. Key words: REA accounting, events accounting, database accounting, semantically modeled accounting, accounting models, accounting...

...a room with a bed, a cupboard, a small table and a washstand has largely been replaced by rooms with modern facilities For the purpose of this work a guest house is (also guesthouse) is a kind of lodging. In some parts of the world a guest house is similar to a hostel, bed and breakfast, or inn whereas in other parts of the world (such as for example the Caribbean), guest houses are a type of inexpensive hotel-like lodging and a hotel is a commercial establishment providing lodging, meals, and other guest services, both of which can be used interchangeably For this Project I would be using The Covenant University Guest House as my case study The Covenant University Guest house has 80 rooms which are divided into three categories; Executive deluxe rooms, mini suits and standard rooms.
