ETL tools are capable of saving an organization time and money through increased productivity by helping it to read Excel in Java among other actions for instance. The first step in establishing whether they are appropriate for an organization is to understand how these programs function and what kind of operations they can perform.
ETL in a Nutshell
ETL is an acronym for Extract, Transform and Load. This software tool is capable of extracting data from external sources, transforming it to fit operational requirements and loading it into an end target. Oftentimes, Data Pipeline ETL engine tools are utilized for data warehousing projects for consolidating data of diverse forms or sources in multiple formats. This data then gets sorted and compiled into a single format, usable by an internal database or other kind of end target.
It is easy to add data to tables or databases, join, filter and store it as desirable, once extracted and stored within a Staging Area. As well, the data can be examined and cleaned easily if needed.
Data is ready for loading into a Central Warehouse that functions much like a database, once it is transformed and saved into the desired format. Data sourced from the warehouse can then get sorted or combined into smaller cubes or pieces of information and utilized as necessary.
Increase Your Productivity
A lot of organizations and businesses are undertaking this sorting, analyzing and transforming manually or even writing their individual custom code for performing the function. Such action requires a lot more staffing and financial resources than does buying a given kind of software from an ETL vendor. An added advantage of utilizing vendor-supplied software is of functionality and crossover utility. When you use custom-designed or custom-coded software it can become hard to maintain, simply because of the manpower needed to maintain it.
An ETL tool is capable of helping to boost productivity by reducing the time-frame that employees spend locating, extracting as well as interpreting data from numerous sources. They can easily learn how to transfer columns from one CSV file into another using Java by example. This is true especially if the data requires being reformatted or transformed into a format their company can utilize. It is also not unusual for the larger organizations especially, to have diverse departments analyzing data of similar form without having a central, shared database. Organizations can avoid such an overlap by combining all data into a single shared database when having the right kind of ETL tool that can for instance read Excel in Java and execute other crucial functions.
ETL tools have the ability of accomplishing a lot more than simply read Excel in Java for example or translate data. These programs can be applied for profiling data, which is vital if one is concerned about the quality of data being utilized. They also prove invaluable in determining whether any data is missing or invalid in a quick and easy way. This can assist in culling bad data from the database source before it gets utilized by an organization.
A credible ETL program should make it easy to execute functions like write a CSV file to database in Java, revise new data only or even that changed since being last updated. Read more at North Concepts
