TECHNOLOGY
AJAX (from
wikipedia)
Ajax, or AJAX, is a
web development technique used for creating interactive
web applications. The intent is to make web pages feel more responsive by
exchanging small amounts of data with the server behind the scenes, so that the
entire web page does not have to be reloaded each time the user requests a
change. This is intended to increase the web page's interactivity, speed,
functionality, and
usability.
The name is shorthand for Asynchronous JavaScript and XML. Ajax is
asynchronous in that loading does not interfere with normal page loading.
JavaScript is the
programming language in which Ajax function calls are made. Data retrieved
using the technique is commonly formatted using
XML, as reflected in the naming of the
XMLHttpRequest
object from which Ajax is derived.
Ajax is a
cross-platform technique usable on many different
operating systems,
computer architectures, and
Web browsers as it is based on
open standards such as JavaScript and XML, together with
open source implementations of other required technologies.
SEACH ENGINE
A search engine is an
information retrieval system designed to help find information stored on a
computer system. Search engines help to minimize the time required to find
information and the amount of information which must be consulted, akin to other
techniques for managing
information overload.
The most popular form of a search engine is a
Web search engine which searches for information on the public
World Wide Web. Other kinds of search engines include
enterprise search engines , which search on
intranets,
personal search engines, and
mobile search engines.
GIS
A GIS is an information system designed
to work with data referenced by spatial / geographical coordinates. In other
words, GIS is both a database system with specific capabilities for
spatially referenced data as well as a set of operations for working with
the data. It may also be considered as a higher order map.
GIS technology integrates common database operations such as query and
statistical analysis with the unique visualization and geographic analysis
benefits offered by maps. These abilities distinguish GIS from other
information systems and make it valuable to a wide range of public and
private enterprises for explaining events, predicting outcomes, and planning
strategies
AI
Artificial intelligence is primarily concerned with symbolic
representations of knowledge and heuristic methods of reasoning, that is,
using common assumptions and rules of thumb. Two examples of problems
studied in artificial intelligence are planning how a robot, or person,
might assemble a complicated device, or move from one place to another; and
diagnosing the nature of a person's disease, or of a machine's
malfunction, from the observable manifestations of the problem. In both
cases, reasoning with symbolic descriptions predominates over calculating.
WEB API
Highly customizable and flexible web application is a demand for sharing and
publishing information around the world. With WEB API, information is shared
and given according to the rule specified by the WEB API owner. WEB API
brings more control to authenticated outsiders so that information can be
utilized in their own wish.
