Datastage Course in Bangalore

What are the core aspects of DataStage?

DataStage (DS) is an ETL tool that extracts data, transforms it, applies business principles, and then loads it to any specific target destination. It is part of IBM’s Information Platforms Solutions suite as well as that of InfoSphere. DataStage uses graphical notations for constructing data integration solutions. It has the ability to integrate all kinds of data, which includes big data at rest or in flux, and over platforms that may be distributed or mainframe in nature. IBM InfoSphere DataStage is another name for DataStage.

DataStage can broadly be classified into two separate entities: as an ETL tool, and secondly, as an ETL designing and monitoring tool. As for the first, it resides in the server and links up with data sources, then targets and processes the data in the application. As such, DataStage jobs can carry out their workings on a single server or even in multiple machines in clusters or grids. For the second part, DataStage offers a set of graphical tools which are based on Windows. This can be utilized for designing ETL processes, monitoring ETL processes, and managing the metadata associated with them. DataStage is available in several versions. Some of the prominent ones include Enterprise Edition, Server Edition, and MVS Edition.

An overview on InfoSphere DataStage :

IBM InfoSphere DataStage is basically a data integration tool used for designing, developing, and running jobs that work with the movement and transformation of data. InfoSphere DataStage is the data integration part of an IBM InfoSphere Information Server. It provides a special graphical framework that can be used for developing jobs that send data from source systems into target systems. The transformed data can then be delivered to data warehouses, operational data stores, real-time web services, data marts and messaging systems, and other enterprise applications. InfoSphere DataStage supports the extraction, transformation, and the loading (ETL) and extraction, loading, and transformation of (ELT) patterns. InfoSphere DataStage utilizes parallel processing and enterprise connectivity to offer a truly scalable platform that can be used to understand and effectively transfer data. The ability to design data flows that can extract information from multiple source systems, manipulate the data as required, and produce the data to target databases or applications. The software lets you connect directly to enterprise applications as its source or target making sure the data is relevant, complete, and accurate. Reduces the time taken for development and improves the design's consistency and deployment by using precoded functions.The time of the delivery cycle is reduced exponentially by working with a common set of tools within the InfoSphere Information Server.

WHAT DOES A DATASTAGE DEVELOPER DO?

Datastage developers work to supervise technological designs and buildings. These developers make use of various tools and solutions. They write up estimations, take an analysis of the requirements, and set up Datastage projects that go in line with the requirements. A Datastage developers' responsibility is to understand the requirements of a business, ensure consistent unit tests, and design applications according to predetermined requirements. Once an update is received, these developers help to support the technology infrastructure team through the implementation and training of clients. To be successful as a Datastage developer, one must know how to design and develop an application, have inherent analytical skills, and be a self-starter.

General Roles of DataStage Professionals :

• Lead the workflow resolution by an automated process thus effectively routing information to appropriate queues with sufficient flexibility that can handle exceptions.
• Be involved in the implementation of UNIX shell scripts that can copy files from different servers and invoke PL/SQL scripts.
• Create an Informix ODBC connectivity using windows in the Datastage environment.
• Upgrade jobs from DataStage 8.1 to 8.5 and the environment from AIX over to LINUX.
• Resolving issues that are related to the compatibility of the code with DataStage 8.7 as well as Redhat Linux server 6.
• Developing SQL scripts that can load data from the source systems and take care of the verification of the data in target tables to accurately load by ETL process.
• Identify rules for business for data migration and the performance of data administration via data models and metadata.
• Convert windows scripts into KSH, Perl, and Perl DBI.
• Deployment and/or the migration process that moves code from DEV to QA and finally to PRD.
• Developing PL/SQL procedures and functions to make reports by retrieving the information from the data warehouse.
• Work intimately with mainframe developers by getting the source files, and discussing data-related issues.
• Work on various types of transformations like a filter, aggregator, row generator, store procedure, and join.
• Use Aggregator stages in order, to sum up the key performance indicators in decision support systems and for granularity requirements in DW.
• Use Zeke job scheduler that makes an automated monthly regular run of DW cycle in both production and UAT environments.
• Use the DB2 stage process to load data into the mart tables. DB2 bulk load stage also loads bigger data chunks into staging tables.
• Use real-time stages such as web services, XML, web sphere MQ connector, and use all of the stages available in the sequencer.
• Extracting all the data from mainframe applications that are available in the hierarchy file system using complex flat file stages.
• Development of stored procedures in DB2 for temporal tables. This reverts data to the initial stage whenever there is termination during a batch cycle.
• Analyze & conceptualize/design the database which serves the purpose of providing critical business metrics.
• The ability to work extensively with user defined functions and stored procedures within SQL to perform specific operations as required.
• Be involved in business needs, evaluate technical alternatives for business and implement them using DataStage.
• Writing UNIX utilities to perform verification and validation procedures. This is done before the transformation of the data.
• Create sessions through ETL methodology for complete processing of extensive data extraction, transformations, and loading using Informatica.
• Create and develop all kinds of front-end and back-end web applications with the use of PHP, Javascript, MySQL, and CSS for clients.
• Define a static and dynamic repository variable to modify metadata content and dynamically adjust to changing a data environment.
• Evaluating Netezza features to change the existing functionality and application performance for a database.
• Re-Design Netezza tables with the proper distribution keys for performance improvement.
• Design/Develop IDQ reusable mappings that match the accounting database on demographic information.
• Provide online and personal technical consulting to program participants within the client organization.
• Develop customer segmentation routines through SAS.

DataStage Modules :

DataStage Module - The reduction of workload and the management of business rules. Optimizes hardware utilisation and can control job activities where resources have exceeded their limit, as well as to reassign job priority.

Administrator: This allows users to interact with administrative projects. It also maintains system interaction and can manage global settings. The administrator's responsibilities range from project setup to property management, as well as adding, deleting, and moving projects. Administrators of the Datastage Repository are provided with a command interface.

Manager: DataStage repository can be viewed and edited; DataStage Manager is the primary interface for the DataStage repository. Manager loads all services,whether we need to search or store the DataStage repository and manage to reuse Metadata. It is critical to organising all tasks to the DataStage Repository.

Designer: This aids in the creation of jobs on DataStage or apps by providing a design interface. From the outside, each job specifies the instinct of data, possible transformations, and the target. The designer will also create an easy-to-use user interface.

Director: DataStage Director will provide an interaction that schedules properly executable programs, formed by the compilation of jobs. It runs, validates, monitors and schedules server jobs and similar jobs. Thus its role in parallel processing. This targets the testers and operators.
