Data Mining and Financial Data Analysis
Most marketers understand the value of collecting financial data, but also realize the challenges of leveraging this knowledge to create intelligent, proactive pathways back to the customer. Data mining – technologies and techniques for recognizing and tracking patterns within data – helps businesses sift through layers of seemingly unrelated data for meaningful relationships, where they can anticipate HR data analysis , rather than simply react to, customer needs as well as financial need. In this accessible introduction, we provides a business and technological overview of data mining and outlines how, along with sound business processes and complementary technologies, data mining can reinforce and redefine for financial analysis.
- The main objective of mining techniques is to discuss how customized data mining tools should be developed for financial data analysis.
- Usage pattern, in terms of the purpose can be categories as per the need for financial analysis.
- Develop a tool for financial analysis through data mining techniques.
Data mining is the procedure for extracting or mining knowledge for the large quantity of data or we can say data mining is “knowledge mining for data” or also we can say Knowledge Discovery in Database (KDD). Means data mining is : data collection , database creation, data management, data analysis and understanding.
There are some steps in the process of knowledge discovery in database, such as
- Data cleaning. (To remove nose and inconsistent data)
- Data integration. (Where multiple data source may be combined.)
- Data selection. (Where data relevant to the analysis task are retrieved from the database.)
- Data transformation. (Where data are transformed or consolidated into forms appropriate for mining by performing summary or aggregation operations, for instance)
- Data mining. (An essential process where intelligent methods are applied in order to extract data patterns.)
- Pattern evaluation. (To identify the truly interesting patterns representing knowledge based on some interesting measures.)
- Knowledge presentation.(Where visualization and knowledge representation techniques are used to present the mined knowledge to the user.)
A data warehouse is a repository of information collected from multiple sources, stored under a unified schema and which usually resides at a single site.
Most of the banks and financial institutions offer a wide verity of banking services such as checking, savings, business and individual customer transactions, credit and investment services like mutual funds etc. Some also offer insurance services and stock investment services.
There are different types of analysis available, but in this case we want to give one analysis known as “Evolution Analysis”.
Data evolution analysis is used for the object whose behavior changes over time. Although this may include characterization, discrimination, association, classification, or clustering of time related data, means we can say this evolution analysis is done through the time series data analysis, sequence or periodicity pattern matching and similarity based data analysis.
Data collect from banking and financial sectors are often relatively complete, reliable and high quality, which gives the facility for analysis and data mining. Here we discuss few cases such as,
Eg, 1. Suppose we have stock market data of the last few years available. And we would like to invest in shares of best companies. A data mining study of stock exchange data may identify stock evolution regularities for overall stocks and for the stocks of particular companies. Such regularities may help predict future trends in stock market prices, contributing our decision making regarding stock investments.
Eg, 2. One may like to view the debt and revenue change by month, by region and by other factors along with minimum, maximum, total, average, and other statistical information. Data ware houses, give the facility for comparative analysis and outlier analysis all are play important roles in financial data analysis and mining.
