                                                 Data Mining Concepts What is Data Mining Data mining is the branch of computer science which deal with huge data. Data mining is a computing process of recognizing patterns in large data using machine learning, statics, and a database system. The extracted information should give us new patterns, relationships, among the data entities. Data mining is also known as knowledge discovery in the database(KDD). The information is extracted so it can be used for the following applications Market analysis Fraud detection Customer retention Production control Science exploration Various data mining methods: these methods help make decisions and predict future 1 Association 2 Classification 3 Clustering Analysis 4 Prediction 5 Sequential Patterns or Pattern Tracking 6 Decision Trees ...

DATA WAREHOUSE Data warehouse is a collection of data that support decision making processes. It provide the following features are ·         Subject oriented ·         Consistent ·         Shows its evaluations over time ·         Non volatile A data warehouse is a central location where consolidated data from multiple locations are stored. It is like a relational database design for analytical processing. DATA WAREHOUSING Data warehousing is the act of organizing data and storing data in a way so as to make its retrieval efficient and insightful. Also called data as the process of transferring   data into information. Is a collection of method, techniques, and tools to support knowledge workers to conduct data analysis that help with performing decision making process and improving information resources.

                                                              Introduction to artificial intelligence The science and engineering of making intelligent machines, especially intelligent computer programs. – John Mc Carthy (AI name was coined by him at 1956). Artificial intelligence is an approach to make a computer, a robot, or a product to think how smart human think. AI is study of how human brain think, learn decide and work. And finally this study outputs intelligent software systems. The aim of AI to improve computer functions which are related to human knowledge, for e.g. reasoning, learning and problem solving. Turing test for artificial intelligence The Turing test was developed by Allan Turing (computer scientist) in 1950. Turing test is used to determine whether or not computer machine can think inte...

DBMS:  The database  management system, is a generalized software system for manipulating databases. It is basically a computerized record-keeping software system; which stores information and allows users to add, delete, change, retrieve and update that information on demand. ADVANTAGE OF DBMS ARE 1. Minimal data redundancy 2. Program-data independence 3. Efficient data access 4. Improved data sharing 5. Improved data consistency 6. Improved data integrity 7. Improved security 8. Increased productivity of application development 9. Enforcement of standards 10. Economy of scale 11. Balance of conflicting requirement 12. Improved data accessibility and responsiveness DISADVANTAGES OF DBMS ARE 1. Increased complexity 2. Required of new specialized skilled manpower 3. The large  size of DBMS 4. Increased installation and management costs. 5. Need for explicit backup and recovery  DATA MODELS:  Data model is a mecha...

A typical computer system irrespective of its size, class or type consists of hardware and software, integrated and synchronized together to perform computational work or data processing. Computer anatomy is concerned with the way the various functional units operate and how they connected together to form the computer system. A computer system consists of the following functional units : 1)  Input unit 2) Memory/Storage unit 3) CPU(central processing unit) 4) Output unit

A system is defined as a set of interacting elements, responding to inputs so as to produce outputs. The computer system also consists of the following elements or components. Software Hardware Firmware Humanware   Software All the intangible components of the computer system are known as software In other words, we can say that all computer programs and applications run behind the monitor screen, are known as software. Computer software is a term that describes computer programs. Example   Microsoft-windows (all operating system software) and notepad, MS office suite, window media player(application software). Software is further divided into two parts these are following 1) system software 2) application software Hardware All tangible component of a computer system is known as hardware. In other words, computer hardware is the collection of physical parts of the computer system. Example  CPU(Microprocessor), monitor, keyboard,...

DATA AND INFORMATION There is a little difference between data and information. Data are the facts or details from which information is derived. Data  Data comes from a singular Latin word "datum" which originally meant "something given." its early usage dates back to the 1600's. Over time data has become the plural of datum. information It is a processed form of data. In other words, when data is processed, organized, structured and useful. For e.g. 32 is data and age 32 is information. Which means information is understandable form.
