Basically, a Browser/Server (B/S) model is adopted in the system design where nearly all computing load is located on the server side, while the client side is only responsible for displaying. In this project, SOA is used to facilitate data communication and interactive operations for the reason that each web service is an independent unit in SOA. The general structure of the web-based UMS using SOA is described as follows (Figure 2). In Figure 2, the server side is composed of GIS web service providers, an image cache server, a web server and a firewall.

In response to the two basic types of urban data at the City of Windsor, two GIS web service providers are devised, respectively a vector data service provider and an aerial photo service. Web service providers are computer servers to publish maps. The vector data service provider is an Object-Relational Database (ORD) based server where all GIS vector data is stored and indexed. The aerial photo service provider is a RDMS based server. High resolution aerial photos are stored in RDMS as pyramid images that can accelerate data distribution at different scales. ArcSDE, a middleware that can facilitate data management, data transfer, and data interaction in one RDMS or among RDMSs, is used to help the data communication between the database servers and map servers.
In order to enhance the efficiency, an image cache server is placed in this system. Maps are usually static, but most map servers render WMS data every time they are queried. This situation can result in unnecessary processing and increased waiting times. In this UMS, an image cache server is added to store all map tiles. When a user requests a map from the cache server...

Additionally, Java Servlet technology is employed to develop certain modules. Java Servlet is a server side procedure, which can respond HTTP requests from the client side. It provides a simple, consistent mechanism for extending the functionality of a web server and for accessing existing business systems (Vandana, 2001). In this project, the printing functionality is developed based on Java Servlet. When a client wants to print the current map and sends the request to the server, the print server will run the print servlet on the server side and respond the client with the requested map in PDF format. The use of Java Servlet can further transfer computing load from the client side to the server side in order to make the client perform only simple tasks, such as sending requests and downloading PDFs.

You might be thinking, “Why would I finance an electric scooter?”, but you’ll be amazed by how easy and cheap it is to purchase an URB-E — the time and money saving vehicle that’s revolutionizing urban commuting.
The purpose of this assignment is to provide an analysis of GIS applications in the real estate industry. The primary focus is on the two most widely used applications of the technology in commercial real estate sector; (1) commercial lending and (2) site selection; however a review of the residential real estate sector, which is in the early stages of implementing GIS, is also included.
...regarded GPS – an indispensable part of GIS. Discussions on cartographic principles, commercial GIS software programs, satellite images, aerial photos, and geodatabases are some of the other conspicuous omissions in this book. There is an inconsistency in the depth of topics explored; for example map projections are explored in great depth, while vector topology is merely glossed over. These omissions and inconsistencies would in my opinion make this book marginally less beneficial to all the three audiences together. However, there is something for all them; structure for engineers, equations for engineers and students, and GIS concepts for students, engineers and users. This book will therefore be undeniably valuable if used to complement the material in some of the other fundamental GIS books in the discipline. It has merits, but there is room for improvement.

Web IS. The importance of web led the classical information systems to transform in order to integrate with web technologies. This means that a web application can access an organization’s dataset. And as we mentioned above, this integration creates new data issues, like security and accessibility.
A trouble ticket system is a software system which works on multi-channel customer requests centralised management. It can help streamline work flow processes, track and solve requests more effectively and improve customer satisfaction. Ticket is this case is as same as medical report which records trouble description, process and result. Finally, it is archived after it closeshttp://doc.otrs.org/3.3/en/html/introduction.html.
GIS is an emerging method of data storage and interpretation. GIS is, simply put a database. It is many tables of data organized by one common denominator, location. The data in a GIS system is organized spatially, or by its physical location on the base map. The information that is stored in the database is the location and attributes that exist in that base map, such as streets, highways, water lines, sewers, manholes, properties, and buildings, etc. each of these items don’t just exist in the database, the attributes associated with the item is also stored. A good example of this would be a specific sewer line, from and arbitrary point A to a point B. Ideally, the sewer line would be represented graphically, with a line connecting the two points or something of the like. When one retrieves the information for that line in particular, the attribute data would be shown. This data would include the size of pipe, the pipe material, the upper invert elevation, the downstream invert elevation, the date installed, and any problem history associated with that line. This is the very gist of what a GIS system is.
When developing an architecture for a system, there are different patterns which can be used depending on the needs of the customer and the requirements of the new system. One of the popular architectures is the client-server architecture. According to Sommerville (2011), the client-server architecture functionality of the system is broken into services with the services being delivered from a server and the clients are the users of the services, (p. 161). An example of client-server is an employee logging into Active Directory network. The computer they are logging into is the client, and then it pulls information from the server to give that employee the rights and access to the network they need for their job duty. The client-server pattern is used when need to share data in databases over a range of locations.
The Geographic Information System (GIS) is used in Saudi Arabia for several projects. The Kingdom of Saudi Arabia is one of the biggest exporter or oil, gas and phosphates; therefore, using GIS is beneficial to them as they understand further information regarding drilling and extracting the two major natural resources. Another aspect in which the geographical information system is used is for projects such as water management. A problem they seem to be facing for years, they finally found a solution to it using the GIS system. The government of Saudi Arabia believes that a successful way of staying ahead of the competition in the real estate business is by using this efficient system. The kingdom of Saudi Arabia is also looking into applying
Proxy / Cache Management: The Windows Media Server can be configured in such a way that it serves as reverse proxy server or as a cache / proxy server. This will allow to provide proxy and caching support to other servers. One of the major advantages of having a server that provides proxy and caching support for the media content is that it reduces operational costs and better streaming for users by offsetting the load from the ori...
The Wireless Markup Language (WML) is used to create pages that can be delivered using WAP. WML is a language that allows the text portions of Web pages to be presented on cellular telephones and personal digital assistants (PDAs) via wireless access. WML is part of the Wireless Application Protocol (WAP) that is being proposed by several vendors to standards bodies. The Wireless Application Protocol works on top of standard data link protocols, such as Global System for Mobile communication, code-division multiple access, and Time Division Multiple Access, and provides a complete set of network communication programs comparable to and supportive of the Internet set of
GIS has been around the block far longer than the internet and the web, with the first GIS being developed by Roger Tomlinson in 1962. This was used for Canada’s Federal Department of Forestry and Rural Development. Other than for conventionally producing maps, GIS more importantly has powerful analytical functions that translate raw data into information that is useful.(Fu & Sun, 2010)
In a particular case study of “Sun County”, the real location name was changed for confidentiality purposes; the implementation of a new GIS (Geographic Information System) was followed for several years in order to focus on the process of e-government rather than the outcome or outputs that other research has focused on (Tsai, Choi, & Perry, 2009). The goal of the new GIS database was for the Department's staff to have the ability to enter data into the GIS database, run reports, and generate maps in a real time manner from their own workstations; this would allow them to provide a high level of service without having to allocate a lot of resources. Another goal of the project was to ease the decision making process of management by giving them the ability to perform analyses to better understand County resources and circumstances (Tsai, Choi, & Perry, 2009).
