How does information become data?

Raw data becomes information once it is organized and sorted. Raw data that is collected, is useless until it becomes information.


What are the difference between database systems and data information retrieval systems?

A database management system (DBMS or simply database) forms the back-end of a data information retrieval system. Data retrieval is just one component of a DBMS; data input, storage and maintenance being the other major components.


What are characteristics of an information system that lead to it having one database and many application processes?

1. The Organization of data into information For data to be made meaningful it must have a purpose. The purpose of the stored data should reflect the purpose and type of the information system. Data needs to be processed and organised before it becomes information. Organising the data will most likely involve the processes of sorting and filtering (classifying) before it can be analysed and stored for later retrieval. Data dictionaries are used to help organise the data. 2. Ability to Analyse the Information Once the data has become information it needs to be analyzed to make the most of the information stored. Analysis of databases is done through the tools of queries and reports. You can find answer in the net.... like i did....XD


What is internal cache information?

A cache is a data store, thus "internal cache information" is metadata relating to a data storage facility that is used solely by a system. That is, a data store that is not intended for user consumption (internal use only).

What is a geographic information system GIS explain advantage of such system?

A geographic information system differs from other computerized information systems in two major respects. First, the information in this type of system is geographically referenced (geocoded). Second, a geographic information system has considerable capabilities for data analysis and scientific modeling, in addition to the usual data input, storage, retrieval, and output functions.A geographic information system is composed of software, hardware, and data. The notion of data layer (or coverage) and overlay operation lies at the heart of most software designed for geographic information systems.

In general what does GIS data mean?

GIS stands for geographic information system. It's a computer technology that allows user to apply a layer of information and data to a geographic map. The examples are population density, wildlife distribution, network coverage, etc.


What is the purpose of using a geographical information system?

How are geographic information systems used?

A geographic information system is also known as a GIS. These systems are designed to capture, analyse, store, manipulate and present a variety of geographical data. These systems can be used with engineering, management, logistics and telecommunications.


What is GIS?

Geographic Information System (GIS), or geographical information system, is any system that captures, stores, analyzes, manages, and presents data that are linked to location. In the simplest terms, GIS is the merging of cartography and database technology.


What do you need to use GIS?

A geographic information system, otherwise known as GIS, generally requires a some type of data collector, many of which nowadays are of the handheld variety. Additionally tools like theodolites, total stations, levels, and positioning antennas are used.


A geographic information system is information that is what?

Geographic information is information that has some spatial component, usually in relation to the earth. The information is stored in spatial co-ordinates and can be one of a variety of geometries, such as a single point, a line of points or an enclosed line of points such as a polygon.A geographic information system can support spatially referenced information. Many kinds of information can have a spatial component. A geographic information system is capable of understanding the spatial nature of the information and provides functionality that supports it.For example, a dataset of national parks in a non-geographic system has no awareness of the geographical position of the park. In a geogrpahical information system the geometry of the park and its spatial location on the earth can be described. With this kind of information the parks can be queried and compared based on geographic properties, such as:the distance between parksthe boundary length or area of the parkspatial querying, for instance parks that are within a bounding areaspatial comparison, what's the biggest park? What is the nearest park to some point?Geographic information systems can often also visualise geographic data: for instance, Google Maps can display the geometry of road information.
