Overview
ETL stands for Extraction, Transformation and Load.
The E represents the capability to constantly and reliably extract data with high performance and minimum impact to the source system. The T represents the capability to transform one or more data sets in batch or real-time into a consumable format. The L stands for loading data into a persistent or virtual data store.
What is Informatica ETL?
Informatica is ETL tool which is extensively used for extracting and transforming source data and load it to target. Informatica is substantially used in data integration and data quality services. ETL is used by organizations for analyzing large and complex data for business decisions. ETL can be defined as a process of migrating and manipulating data and converting it to target database.
Context behind Data Integration
The Problem:
Large organizations have a lot of data which can be stored in numerous formats including databases and unstructured files. This data must be collated, combined, compared and made to work as a seamless whole but the different databases don’t communicate well. Many organizations have implemented interfaces between the databases:
Every pair of databases requires a unique interface
If you change one database, numerous interfaces have to be upgraded.
The Solution:
Data integration technologies allow applications using different databases and formats to communicate with each other using only one interface each.
Data Integration
Data integration is the method, technique and technology that deals with the extraction, restructuring, movement and loading of data to logical data stores or repositories in order for it to be used by logical/reporting operations and systems. A framework of operations, products, techniques and technologies for furnishing a unified and harmonious view of enterprise-wide business data.
Goal of Data Integration: Provide uniform access to data available in multiple, independent, heterogeneous and distributed data sources
Uniform (same query interface to all sources)
Access to (queries; eventually updates too)
Multiple (Involves multiple sources)
Autonomous (Independent solution)
Heterogeneous (data models are different)
Distributed (over LAN, WAN, Internet)
Data Sources (not only databases)
Components of ETL
ETL tool has various components like Informatica Domain, repository services, administrator console, source, target, etc.
Informatica Domain:
It is an administrative unit consisting of nodes and services. There are two types of services. They are:
Service Manager: It is responsible for authenticating or authorizing the logins.
Application Service: It is responsible for running the application services.
Repository Service
It maintains the connection between client system and PowerCenter repository. It is a multi-threaded process that fetches, serves and updates the metadata.
Reporting Service
These are responsible for handling the metadata and allowing the services to access the same.
Integration Service
This is responsible for executing the tasks created in the informatica tool. As soon as the workflow is executed, the integration service gets the details and executes it.
Is ETL becoming a history with the advent of Big Data?
1. Data needs to flow from source operations into logical data stores in a controlled, dependable, secure manner.
2. Information needs to be formalized, with regards to semantics, format and lexicon, for accurate analysis.
3. Functional results need to be harmonious and repeatable.
4. Functional results need to be verifiable and transparent.
5. Facilitates integration of data from various data sources for building a data warehouse.
6. Businesses have data in multiple databases with different codification and formats.
7. Transformation is needed to convert and to summarize functional data into a consistent, business-oriented format.
8. Pre-Computation of any derived information
9. Summarization is also carried out to pre-compute summaries and aggregate.
10. Makes data available in a query-able format.
