If every processing, search, purification had to be done individually. It is enough to imagine how hard and laborious it would be to work with data if we had to be an expert on every data source that is processed in our company. The list of possible applications of the ETL tool goes beyond these four most characteristic points, but clearly shows how important it is to use ETL in everyday business operations. Linking our data with databases of suppliers and business partners.Integrating company data after acquisitions, mergers or purchase – all activities related to the development and growth of the company.Importing data from old, no longer used analytical systems into new ones.Collecting data from different sources (different types of databases), different departments of the company (production, logistics, sales, accounting) and creating data warehouses from them.What possibilities does the ETL tool give us?
Our extracted and transformed data must be loaded (pulled in, uploaded) into the target database, which will be the basis of our analysis. It is also a stage that transforms data so that it is compatible and can be analyzed as such. That is why it is so important to prepare this data according to the needs, requirements and standards of each client individually. Every company wants to learn other things from their data. Data must be consistent – homogeneous – to give a clear and true message. Different sources, different standards, different formats. In order to make a full analysis we need to extract the data we need from the source. At different stages this trace can be saved in different ways, in different databases.
Nowadays, everything, every object that surrounds us, that we use, that we want to buy leaves a trace.
