What is ETL (Extract, Transform, Load)?
To understand this professional word, some knowledge might be hard to learn and grasp.
What Is ETL (Extract, Transform, Load)?
Many people might be curious about that why you need ETL.
In this era where cloud data becomes the mainstream, ETL seems less important in a traditional data warehouse.
How Does the ETL Process Work?
In this ETL process, three steps are included to enable data integration from source to destination.
There are some steps in data transformation:
Cleansing inconsistencies and missing values in the data are resolved.
Standardization formatting rules are applied to the dataset.
Deduplication redundant data is excluded or discarded.
Verification unusable data is removed and anomalies are flagged.
Sorting data is organized according to jot down.
These are two different methods of Loading.
Incremental Loading A less comprehensive but more manageable approach is incremental loading.
This architecture allows smaller, less expensive data warehouses to maintain and manage business intelligence.

ETL vs ELT
The most obvious difference between ETL and ELT is the order of operations.
ELT is particularly useful for large-volume unstructured data sets because it can be loaded directly from the source.
ETL processes, on the other hand, require more definition at the beginning.
May you have a good day.
