Abinitio:
    Grew up as a speed mongor.  They did not start with metadata first, their whole purpose in life was bent on making the base OS: a) fault-tolerant b) fast c) partitionable flat file access.   – that’s right, it’s all 100% flat-file driven.  So what they did was create something called the Co-Operating system.  The co-operating system basically is a parasite.  It sits on top of your existing OS, and pluggs in to the I/O interrupt level – it assumes and overrides 100% of all file operations on the machine.  Even files that aren’t “running” through Ab-Initio go through the AB-I interrupts at the file system level.

    They then, constructed their own “data description and manipulation language” known as ab-initio scripts (much the same way C-Shell, or K-Shell acts in unix).  They interpret these scripts at the start of a run-request (compile them really), and then figure out mathematically what operations can be split across which resources.  Their only notion of a shared repository (at that time) was the systems-performance metadata.  They gather this metadata from each registered system upon install to make a profile of the machine’s capabilities.  This makes heterogeneous activity possible, and load-balancing mathematically easy.  It’s also why when you upgrade your OS, or upgrade your hardware that you’re asked to re-run the machine profile, and re-register it with the “central brain”.

Key Features:
    Ab Initio is a commercial licensed tool and a most costlier tool in the market.
    The basic features of Ab Initio are easy to learn.
    Ab Initio Co>Operating system provides a general engine for data processing and communication between rest of the tools.
    Ab Initio products are provided on a user-friendly platform for parallel data processing applications.
    The parallel processing gives capabilities to handle a large volume of data.
    It supports Windows, Unix, Linux and Mainframe platform.
    It performs functionalities like batch processing, data analysis, data manipulation etc.
    Users who are using Ab Initio product have to maintain confidentiality by signing NDA.

Talend:
    Talend is a free open source ETL tool.
    It is the first commercial open source software vendor for data integration.
    Over 900 inbuilt components for connecting various data sources.
    Drag and drop interface.
    Improves productivity and time required for deployment are using GUI and inbuilt components.
    Easily deployable in a cloud environment.
    Data can be merged and transforms traditional and Big Data into Talend Open Studio.
    The online user community is available for any technical support.
