Informatica is a (ETL) tool Extraction, Transformation and Loading. It is used for building enterprises with data warehouses. The main aim of informatica tool is to extract the data from its source and transforming as per the business requirements. Finally, it's loaded into the targeting data warehouse.
What is Extract, Transformation, and Load?
ETL refers to trio of processes that can be performed from moving raw data to data mart and data warehouse.
Why do we need ETL?
Creating a new data warehouse is common for the data from disparate sources. It will be easy for analyzing the insights and patterns. Getting the data from the outside source would be great for outset in compatible schema, but it's a rare case.ETL takes the heterogeneous process and converts it into a homogeneous process. Without ETL there will be difficult to find (or analyze) the heterogeneous data.
What does the ETL execute?
Extract - First phase in the extraction process, data can be collected from more than one data source and it would be held in a temporary storage, where the subsequent phases are executed. During extraction, the validation rules are tested, if the data is valid it will further move to the next step. It the data fails the validation is rejected, then analyze why the data are rejected and further proceed to recover that why it is failing.
Transform - Second phase in the transformation process, the main goal of transformation is scheduling the process. The data will be processed to make structures consistent and values for all data's. Typical transformations like resorting rows, date formatting, conversely, splitting data like one into two, etc.
Load - Third phase in the loading process, it moves from transformed to permanent data. Once loaded the process will be completed, although many organizations are performed ETL regularly to update the data warehouse with the latest data.
Advantages of using Informatica as an ETL Tool over Teradata
Informatica over Teradata
1. Recovery and job monitoring
Easy to recover the failed jobs and slow running process.
Easy to monitor with the help of an Informatica workflow monitor.
2. Informatica marketplace
Single failure stop shops for excess of tools for enforma that accelerators makes SDLC faster and improve the application support.
Major advantages of informatica
Communication- With the help of new information technologies our process will be done easier way.Instant messaging, voice, emails, video calls become very much quicker and cheaper with much more efficient.
Availability-The availability-business will open at anytime, anywhere, purchasing process will be much easier for different countries .It saves our time to do our work. It also helps to deliver the goods at your doorstep. It makes the business to open in 24×7 all over the globe.
Creating a new type of jobs - The main advantage is to get the interesting jobs with new creation.System Analysers, Computer programmers, Web designers are surrounded on all over the world.
Globalization and cultural gap -By implementing new technology,we can get the geographical, linguistic and cultural boundaries. Sharing the information, communication, knowledge, cultures are much easier.
Disadvantages of Informatica
Unemployment and lack of job security - Technology is improving day by day, it is much easier to do our task. Most of the tasks like financial transaction, online purchasing can be done in a short period of time.
Security issues - Hackers and thieves can get access to our identities. Such data includes bank records, vendor information, etc. Hackers are distributing the information over the net and it into the rival companies.
