This project focuses on the context-aware system support applications that make use of context information including user location, time and date, neighboring environment etc. with the contents uploaded over internet. Such types of applications are easily integrated in mobile devices such as PDA, mobile phones and so on. In addition, multimedia contents may also be added for extended data management to be applicable over a large group of consumers.
Thisproject describes a simple algorithm implemented on a smalldatabase. The project work has been completed in two languages: MySQL and PHP. MySQL is used to create and maintain the database while making it easily searchable by issuing related queries. PHP or Hypertext Preprocessor is the language used to create the interface between webpage and the database. When used along with MySQL, it enhanced the database searching while giving the freedom of a scripting language. Asthe multimedia content in the database increases, there is practically no room left for any search that cannot return anything related to the subject matter. Thus, it becomes highly necessary to constrain the data retrieval from the database to better suit what the user is looking for.
In addition, this project provides a practical example by restricting the search based on the distance from the geographic location of the user. In this project, a simple algorithm to constrain the search from the database based on the most popular entry within a given distance is demonstrated. |
