IntroductionIntroduction
Nowadays there is also a great amount of applications and services that are available through Internet as they are seeking, chats, sales, etc.
Knowledge discovery is a concept that describes the process of searching on large volumes of data for patterns that can be considered knowledge about the data.
Three kinds of data warehouse applications Information processing:-
Supports querying, basic statistical analysis, and reporting using cross tabs, tables, charts and graphs.
Analytical processing:-Multidimensional analysis of data
warehouse data supports basic OLAP operations, slice-dice, drilling, pivoting.
Data mining:-Knowledge discovery from hidden patterns
supports associations, constructing analytical models, performing classification and prediction, and presenting the mining results using visualization Tools.

1960s:Data collection, database creation, IMS and
network DBMS. 1970s:
Relational data model, relational DBMS implementation.
1980s: RDBMS, advanced data models (extended-
relational database ), Application-oriented DBMS (spatial, scientific,
engineering, etc.). 1990s:
Data mining, data warehousing and Web databases.
2000s:Data mining and its applications Web technology
(XML, dataintegration) and global information systems.
Evolution of TechnologyEvolution of Technology
Data mining, the extraction of hidden predictive information from large databases, is a powerful new technology with great potential.
Data mining is a knowledge discovery process in large and complex data sets, refers to extracting or “mining” knowledge from large amounts of data.

Data Mining ApplicationData Mining Application
Usually, web mining is categorized as web content mining and web usage mining.
Both usage and content attributes of a site is
described. Some techniques based on clustering and association rules are proposed.
Web MiningWeb Mining
Social data mining is a new and challenging aspect of data mining.
Social data mining includes communities, searching for multimedia data (images, video, digital photos, audio recordings etc) .
It also search personalization search methods for social activities (find friends), text mining for blogs or other forums.
Social Data MiningSocial Data Mining
More recently, stated that “privacy is about self-possession, autonomy, and integrity.”
Another view is corporate privacy – the release of information about a collection of data rather than an individual data item.
For example:-I may not be concerned about someone knowing my birth date, mother’s name, or social security number.
