Data Minining and Data Discovery Research Paper

Data Minining and Data Discovery - Research Paper Example However, the data that is analyzed via different techniques is fetched from data warehouses, where many databases are interconnected with each other. Major techniques that are involved in the process of data miming are regression, classification and clustering. Data mining is incorporated for gaining in depth patterns for market intelligence from data warehouses containing massive amount of data. However, the issue that arises is not the quantity of data, as we already have massive amount of data to work with, it is the methodology that is required to learn data. 3 Data Mining 3NF is usually recommended for a corporate environment managing massive amount of replicated data. For instance there is no requirement of saving data several times. However, there is a requirement of doing more joins. Comparatively, 1NF will provide the functionality of storing replicated data regardless of number of joins. It is the choice of database administrator to evaluate what is the right form; it may b e 3NF or 1 NF. Moreover, normalization comprises of five rules that are applied on a relational database. The main objective is to eliminate or minimize the redundancy and at the same time increasing database efficiency. The negative part illustrates that too much implementation of normalization can cause issues. The objective is to deploy the highest acceptable level of normalization. If we compare three of these NF’s, the 1NF removes replication in groups. The 2NF reduces data replication or redundancy and the 3NF reduces columns from the tables that are not reliant on primary keys. Therefore, database design must demonstrate the highest level of normalization possible, in order to make database efficient and robust. In order to maintain 3 large databases for a VLDB and to keep them efficient for two years if required, there is a requirement for constructing a ‘store and forward’ mechanism that will process the data or information from and through each distribu tion center database. Likewise, at the same time embrace that data or information pending till the completion of EDW. Moreover, data archiving is also required for maintaining each distribution center becoming a VLDB. EDW is efficient enough to support this scenario. A study demonstrated the overall cost of this disease throughout the world is $376 Billion annually. It is now almost fundamental that a person exceeding an age of 60 have more chances to get this disease, as it is now considered as the fourth largest live taking disease globally along with making its name for the fourth most common disease that contributes to a death of a person. However, the most common of all diabetes is the type 2. As there are almost 20% habitants suffering from in the United Arab Emirates alone, many research studies and debates are conducted yearly in Dubai and Abu Dhabi. Moreover, awareness sessions are conducted in every town of the cities to aware the people about this disease (MoH launches se cond phase of diabetes campaign.2010). However, this case study demonstrates the disease diabetes and medical data associated with patients from the Middle east region i.e. United Arab Emirates for discovering concealed patterns and the valuable information that can be utilized for decision making process. In addition, these informed decisions are performed by medical personnel
