The involvement and evolvement of data in today’s businesses is growing leaps and bounds. The value of data and its importance in taking business decisions is now indispensable for organizations. Managing customer information, studying trends and patterns, analyzing KPI and metrics are all fundamental processes for effective business output.
One such process that can help in getting the best out of data is ETL and ETL software tools today are competent enough to optimize capabilities and avail real-time information from data warehouses.
Before we plunge into the pool of best ETL tools, let us glance through the fundamentals of ETL and its salient features.
What Is ETL?
In computing, extract, transform, load (ETL) is the general procedure of copying data from one or more sources into a destination system that represents the data differently from the source(s) or in a different context than the source(s) – Wikipedia
ETL signifies E – Extract, T – Transform, and L – Load. It is the approach that data engineers leverage for extraction of data from disparate sources, transformation into accurate information, and loading of that data into approachable, consolidated systems – the data warehouses. It enables detailed analytics of data that can be used for resolving business issues and offer insightful business information for further prospects.
It holds an important place in data integration processes, facilitating a variety of data to work together. As an important arm of the data engineering process, ETL is the core process for any type of data management. It is a trilogy of procedures that deal with heterogeneous databases leading to data in consolidated data warehouses.
Functions of Extract, Transform, Load –
- Converts data from various data sources and gets necessary data sets
- Retrieves needed data with the best utilization of resources
- No disturbance to data sources, performance, and operating processes
- Filtering, cleansing, and data readiness for extracted data
- Validation of records, contradiction, and assimilation of data
- Sorting, filtering, clearing, standardization, translation, and verification of data
- Extracting and transforming data to a data warehouse and then writing of data output
- Inserting records physically as new rows in tables or linking of procedures from the major source
Key Features Of ETL:
- Extraction of meaningful insights and patterns
- Conversion of assorted data into a consistent and accurate form
- Enhanced derivation of business intelligence from data
- Possesses readily usable components
- Easy management of complicated transformation
- Maximum Return on Investment
- Support for all types of data management
- Perfect data formats and accuracy
What Is ETL Tool?
It is interesting to perceive what is ETL tool and what can it do. A single ETL tool performs all three processes as a single unit. Hence, the responsibility that it shoulders is quite high. It must offer accurate, secure, usable data for further analytics.
Over the years, the configuration of ETL tools has evolved and some best ETL tools have come up as competitive alternatives.
Organizations today need an ETL tool because of the following reasons:
- Streamlining of data pipeline procedures
- Reduction in manual processes
- Managing repeatable and mundane tasks
- Involvement of latest technologies like IoT, AI, and ML
- Data governance requirements like GDPR etc.
- Ensuring data quality and secure, trustworthy information
