Choice?. Big Data The curse of data explosion Virtually every larger enterprise struggles with the problem of data redundancy.
Data is produced by almost every electronic device and various types of systems supporting the operational activities of the organization. These include systems for: enterprise resource planning customer relationship management warehouse management financial and accounting systems production systems and many others often specific to the company's area of activity. These systems usually store data in third normal form databases. What does Email Marketing List it mean? There are three types of relationships in databases. First normal form = PN NF = First normal form each attribute in the table has an elementary value no repeating groups of information the table has a key;. Second normal form PN NF Second normal form the table should store data regarding only a specific class of objects.
Third normal form PN NF Third normal form each nonkey attribute is directly dependent only on the primary key. At some point every company must face the problem which is not the lack of access to data or its scarcity but excess difficult processing and the inability to transform it into knowledge and effectively use it in the decisionmaking process. The answer to this problem is a data warehouse whose task is to integrate heterogeneous enterprise data i.e. coming from many sources.
