...systems approach can be applied to the solution of many types of problems. When this involves the development of information system solutions to business problems, it is called information systems development or application development. Most computer-based information systems are conceived, designed, and implemented using some form of systematic development process. In this process, end users and information specialists design information systems based on an analysis of the information requirements of an organization. Thus, a major part of this process is known as systems analysis and design. When the systems approach is applied to the development of information system solutions, a multistep process or cycle emerges. This is frequently called the information systems development cycle, also known as the systems development life cycle (SDLC). Steps involved and products produced in the traditional information systems development cycle: 1. Systems investigation - Product: Feasibility Study 2. Systems analysis - Product: Functional Requirements 3. Systems design - Product: Systems Specifications 4. Systems implementation - Product: Operational System 5. Systems maintenance - Product: Improved System 1. All the activities involved are highly related and interdependent. 2. Several developmental activities can occur at the same time. 3. Different parts of a development project can be at different stages of the development cycle. 4. Analysts may recycle back at any time...

...INTRODUCTION 1. INTRODUCTION Telecom Connections is a web based application through which user can effectively use the benefits of Telephone Provider. We have analyzed the needs of the users, and thus developed a web based application, for providing telephone connections and associated services online. Because now a days people became so busy with their work and they don’t want to waste their time by going and waiting for long time or waiting in a queue for applying for new connections or to get their bills or to give the complaints regarding the service. Also they are not sure whether waiting for that much time , they will get their turn or not. If so they will get out with frustration .By considering all this issues associated with the manual process we have developed a web application for the telecom users , where in the user can apply for new connections online , can view the bill status online , can send the feedback and do complaints regarding the service provided by the telecom company. 1. PURPOSE OF THE PROJECT: We are going to build an automated system where user can online apply for phone connections and they can view their telephone bills and they can also post the complaints details. EXISTING SYSTEM AND PROPOSED SYSTEM 2. EXISTING SYSTEM AND PROPOSED SYSTEM 2.1 PROBLEMS EXISTING IN SYSTEM: In existing system user has no option of online. He has to go to telecom office...

...and Conflict Research Methods Assignment In the field of political and international relations studies, there are two broad types of research methods, which include and combine various research methods, based on its designs and core principles, and they are quantitative and qualitative research methods. Also, there is the third one, called experimental research method, which does not fit into qualitative and quantitative methods, but rather constitutes separate research design, although it might be based on qualitative and quantitative methods’ tools and theories. Quantitative research methods include many particular techniques and in general could be described as methods, which works with numbers and applies statistical analysis by using various mathematical operations with formulas and computer software. The usage of surveys and various types of databases are examples of quantitative methods. Scientists conduct surveys either in person, or through telephones, mail or internet to collect data concerning people’s opinion and attitudes about particular events in politics and international relations (Box-Steffensmeier, 2008, p. 9-10). Then, gathered information could be analyzed through the coding of data into numbers and application of tools of statistical analysis on them. Surveys allowed scientists to form databases from the collected data that made it possible to share databases with other scientists, especially with the emergence of internet, test theories or do further research...

...Phoenix BSA/375 July 15, 2010 Riordan Manufacturing HRIS Analysis The ability to analyze and study the needs of an organization is an essential skill for a systems analyst. A systems analyst uses the concept of analysis and design to maintain and improve their information systems. The main goal of systems analysis and design is to improve organizational systems, typically through applying software that can help employees accomplish key business tasks more easily and efficiently (citation). The first steps that need to be taken in systems improvement are research and analyzing the scope and feasibility of a new project. Systems Analysis Approach The information-gathering technique and design method proposed for this project is the Rapid Application Development method, acronym RAD. The RAD methodology is a process in which research of user requirements is compiled before producing any detailed system design documents. Using this approach decreases the time needed to design and implement new systems. Factors of Successful Analysis The Rapid Application Development method incorporates using three different approaches of systems analysis. These sub-approaches are Prototyping, Computer-Assisted Software Engineering Tools, and Joint Application Design. By using the three different perspectives, RAD streamlines the entire systems analysis and design process. Prototyping Prototyping is the building of a raw and small-scaled working model. This...

...CHAPTER ONE INTRODUCTION 1. BACKGROUND OF THE STUDY User authentication for network or internet based environment posed a challenging task for system and network administrator. This statement is true and is still very much applicable till these days as it is a well known fact that authentication is being widely incorporated as part of access control for most systems. Authentication has been the catalyst for business organization in information protection and security. Implementation of access control policies, standards or procedures involves the identification of appropriate authentication mechanism whereby the criticality of the information being protected are being used as justification for having a more refined authentication mechanism as compared to a more simple approach. Without the appropriate authentication mechanism in place, attacker could easily gain access to systems or applications by utilizing personal information, gained through various means, including but not limited to social engineering. Conventional textual passwords are the most common mechanism used in authentication. This method requires a user to enter their username and password, either in alphabet or numeric, or more commonly, a mixture of both forms as authentication tokens to gain access to systems or applications. Two recent surveys have shown that users choose short, simple passwords that are easily guessable, for example, “password”, personal names of family members, names...

...Riordan Business-to-Business Web Site Use Case Scenarios Analysis In deciding which way to take Riordan Manufacturing’s business-to-business web site use case studies were performed and the top two scenarios were chosen for further analysis. Both scenarios present a way for Riordan to improve raw material ordering through different means. In order to decide which path to take the two scenarios will be discussed in greater detail including a brief synopsis on the technological role involving systems analysis and design, database design, programming, networking, and the web. Use Case 1 As described before, in use case scenario 1, a Riordan employee would log into a business-to-business web site and place an order with one of our partnered vendors as Figure 1 depicts. The employee logs into the secure website, chooses a vendor from a list, selects from the common list of products purchased from the vendor, chooses a quantity and enters a required by date, the vendor receives notification of an order, verifies credit status or requests credit card information, fills the order, generates an invoice, and ships the order to our warehouse. Use Case 2 In use case scenario 2, as shown in Figure 2, the approach to replenishing key inventory levels resides with the vendor. Triggers in the database alert the vendor via email that the level is at its threshold and then the supplier logs into the secure business-to-business web site, issues an order to ship replenishment supplies...

...Why Normalization Failed to Become the Ultimate Guide for Database Designers? Marin Fotache Alexandru Ioan Cuza University of Iasi, Romania Faculty of Economics and Business Administration Dept. of Business Information Systems Blvd. Carol I, nr. 22, Iasi, 700505, Romania Tel: + 40 744 497 654, Fax: + 40 232 217 000 fotache@uaic.ro ABSTRACT With an impressive theoretical foundation, normalization was supposed to bring rigor and relevance into such a slippery domain as database design is. Almost every database textbook treats normalization in a certain extent, usually suggesting that the topic is so clear and consolidated that it does not deserve deeper discussions. But the reality is completely different. After more than three decades, normalization not only has lost much of its interest in the research papers, but also is still looking for practitioners to apply it effectively. Despite the vast amount of database literature, comprehensive books illustrating the application of normalization to effective real-world applications are still waited. This paper reflects the point of 1 view of an Information Systems academic who incidentally has been for almost twenty years a practitioner in developing database applications. It outlines the main weaknesses of normalization and offers some explanations about the failure of a generous framework in becoming the so much needed universal guide for database designers. Practitioners might be interested in finding out (or confirming)...
