You may also choose to watch YouTube tutorials to round out your knowledge of ETL. The mode of study you choose depends on what works best for you.

Data Integration

Data integration is the process of combining data from different sources into a single, unified view. Integration begins with the ingestion process. It includes steps such as cleansing, ETL mapping, and transformation. Data integration ultimately enables analytics tools to produce effective, actionable business intelligence.

There is no universal approach to data integration. However, data integration solutions involve a few common elements. It may include a network of data sources, a master server, and clients accessing data from the master server.

In a typical data integration process, the client sends a request to the master server for data. The master server then intakes the needed data from internal and external sources. The data is extracted from the sources, then consolidated into a single, cohesive data set. This is served back to the client for use.

ETL: Extract – Transform – Load

ETL is a data integration process. It refers to the three distinct, interrelated steps of extract, transform, and load. The process involves extracting data from different systems and transforming it. Then load it into the appropriate data warehouse. 

Using ETL, businesses can gather data from a variety of sources. It can consolidate it into one centralized location. The three functions are defined as follows:

  • Extract. This is the process of gathering data from multiple sources.
  • Transform. In this step, the data is converted into a form that can be stored in the database. In the transformation process, related data are combined with other data using rules or lookup tables.
  • Load. This is the process of writing the data into the correct database. 

Anyone with experience in data hubs, data warehouses, or data lakes will understand the need to extract, transform, and load data. It is an excellent approach to data processing that will result in better performance. 

Use Of ETL

ETL is used to seamlessly migrate data from one database to another. The process is efficient when loading data from data warehouses and data marts. It is also reliable in converting the format of large databases.

In the digital era, most businesses recognize the need to prepare data and store it properly. The use of ETL has made it a go-to solution for many companies and corporations. Below are some of the possible uses of ETL.

  • Providing Historical Context

Businesses can acquire historical context when using ETL with an enterprise data warehouse. It provides extended reference material for both old and new data. 

  • Giving A Consolidated View

ETL provides a common data repository. This makes it easier to analyze, visualize, and evaluate large data sets.

  • Improving Productivity

With ETL, there is no need for technical assistance, as it can code and reuse processes to transfer data. There is no need to hand-code a migration of big data.

  • Making Business Decisions

Companies can make well-informed decisions. When they are strategizing based on proper data analysis. ETL can be used to tackle complex business problems. These are the problems that a traditional database could not handle.
