ETL testing online training:

 ETL the term stands for Extract-Transform-Load. This is a process of loading data from the source system to data warehouse. The ETL tool helps extract data from different data sources and transforms the data such as applying calculations, keys fields, removal of incorrect data fields, and so on. This is loaded into the Data Warehouse.

Key operations of the ETL Tool:

·         Extracting data from your transactional system that may be Oracle, Microsoft, or any relational database

·         Transforming data by performing cleansing operations.

·         Loading data into the OLAP data Warehouse.

Take a look at some of the ETL Tools used:

o    SAP BO Data Services (BODS)

o    Informatica – Power Center

o    Microsoft – SSIS

o    Oracle Data Integrator ODI

o    Talend Open Studio

o    Clover ETL Open source and so on.

One may extract data from flat files such as spreadsheets and CSV files with the use of the ETL tool and load the same into the OLAP data warehouse for further data analysis and reporting. ETL tool-based data warehouse uses the staging area, data integration, and access layers in order to perform its operations. It is generally said to be a 3-layered architecture

 ·        Staging Layer – This is used to store data that is extracted from different data sources.

·        Data Integration Layer – This is used to transform the data from staging layer and moves data to the database, where it is arranged in hierarchical groups, termed as dimensions, facts and aggregate facts. This combination of facts and dimension tables in a Data Warehouse system is said to be schema.

·        Access Layer – this is used by the end-users in order to retrieve data for analytical reporting and information.

 ETL Testing training is especially useful for software testing professionals who perform data analysis in order to extract the relevant information from the database.

It is good for the ETL learners to have hands-on experience in handling the database using different SQL queries. In addition to the same, it helps learners when they have elementary knowledge related to data warehousing concepts.

Data Modeling:

Data Modeling is the first step to design the database and object oriented programming. It is the foundation for users to communicate information across businesses and developers for an effective Database. Data Modeling today stands as one of the most essential tools for Data Management that enables organizations to configure complex data from different sources in a unified form.

A Data Model for a Data warehouse stands as the information framework for business intelligence. It is the foremost step that constructs a potential and a flexible Data warehouse. A data model helps the organization reach a common understanding with regards to various business concepts.  

A well-structured logical data model permeates the stake holders to distinguish the errors and make the appropriate changes before the programming code is written. Multiple Data models are used in order to view data to ensure that all processes, entities and data flows are analyzed.

Today organizations derive upon various strategies to deal with vast unstructured data to improve their business. The Data Modeling training online is designed in a way that you can draw data model representations from complex to simple ones in an efficient manner.

The data model may be re-designed or a blue print may be created for the same.

BYTES’s Data Modeling Online Training provides a complete understanding of how to design the flow chart representing the relation between data and different entities.  

Data modeling course online is designed with the key concepts such as Layer Architecture, Relational Data Models, Schemas, Methods, Attributes and more.
