About Data mining?
Right now many business either online or offline requires atleast a basic software to run the business. Definitely data and database are the key factors for all business to determine their important decision on various data analysis. Right now all businesses are facing problems with too much of data with a great deal of info on hiding within it, but “hiding” is the right word which we can define this. So much data exists that it overpowers traditional methods of data analysis.
Data mining paves a way to get all the information buried in the data. Data mining creates models to find various hidden patterns and it can done for dataWhich are large, complex collection of data, patterns that sometimes elude traditional statistical approaches to analyze because of the large number of attributes, the density of patterns, or the difficulty in performing the analysis.
Data warehousing Concepts — Role of data mining in database?
Data mining normally require a considerable amount of data collection and data processing before and after model building. Data tables can be done by combining various types and sources of information. The fact is the actual data is often dirty, that is, includes wrong and missing values, all business should take utmost care and most often be cleaned before it can be used. Data is filtered , trimmed, sampled, transformed in various ways using data mining. Up to 80% of hard work in a data mining project is often dedicated to data preparation when the data is stored in a table inside a database, data preparation can be used through database facilities.
Data mining models consist of testing, validating , managing and then deployment in their appropriate application domain environments. The data mining results may need to be post processed as part of domain specific computations such as for ex. Calculating, estimated risks, expected utilities and response probabilities and then stored into permananet databases or data-warehouses.
Challenging job is to make the entire data mining process work in a reproducible and reliable way, it may involve automation and transfers across servers, data repositories, applications and tools . For example, some data mining tools require that data be exported from the corporate database and converted to the data mining tool’s format; data mining results must be imported into the database. Removing or reducing these obstacles can enable data mining to be utilized more frequently to extract more valuable information and, in many cases, to make a significant impact on the bottom-line of an enterprise. Data mining in the database makes the data movement required by tools that do not operate in the database unnecessary and make it much easier to mine up-to-date data.
