You can download the Pentaho from URL:- of Pentaho Data IntegrationPentaho Data Integration is an extremely flexible tool that addresses a broad number of use cases including:Data warehouse population with built-in support for slowly changing dimensions and surrogate key creationData migration between different databases and applicationsLoading huge data sets into databases taking full advantage of cloud, clustered, and massively parallel processing environmentsData Cleansing with steps ranging from very simple to very complex transformationsData Integration including the ability to leverage real-time ETL as a data source for Pentaho ReportingRapid prototyping of ROLAP schemasHadoop functions: Hadoop job execution and scheduling, simple Hadoop MapReduce design, Amazon EMR integrationA transformation is a network of logical tasks called steps. Transformations are essentially data flows. In the example below, the database developer has created a transformation that reads a flat file, filters it, sorts it, and loads it to a relational database table.The two main components associated with transformations are steps and hops:StrepsSteps are the building blocks of a transformation, for example a text file input or a table output. There are over 140 steps available in Pentaho Data Integration and they are grouped according to function; for example, input, output, scripting, and so on. Each step in a transformation is designed to perform a specific task, such as reading data from a flat file, filtering rows, and logging to a database as shown in the example above. Steps can be configured to perform the tasks you require.HopsHops are data pathways that connect steps together and allow schema metadata to pass from

Well, we have the comprehensive Pentaho Course to give you a head start in your career.5. What is the importance of metadata in Pentaho?A metadata model in Pentaho formulates the physical structure of your database into a logical business model. These mappings are stored in a central repository and allow developers and administrators to build business-logical DB tables that are cost effective and optimized. It further simplifies the working of business users allowing them to create formatted reports and dashboards ensuring security to data access.All in all, metadata model provides an encapsulation around the physical definitions of your database and the logical representation and define relationships between them.6.

Attributes.23. Give a brief about PDI architecture.Below image depicts the architecture of PDI24. Explain Pentaho report Designer (PRD).PRD is a graphic tool to execute report-editing functions and create simple and advanced reports and help users export them in PDF, Excel, HTML and CSV files. PRD consists of Java-based report engine offering data integration, portability and scalability. Thus, it can be embedded in Java web applications and also other application servers like Pentaho BAserver.25. Define Pentaho Report types.There are several categories of Pentaho reports : Transactional Reports : Data to be used form transactions. Objective is to publish detailed and comprehensive data for day-to-day organization’s activities like purchase orders, sales reporting.Tactical Reports : data comes from daily or weekly transactional data summary. Objective is to present short-term information for instant decision making like replacing merchandize.Strategic Reports : data comes from stable and reliable sources to create long-term business information reports like season sales analysis.Helper Reports : data comes from various resources and includes images, videos to present a variety of activities.26. What are variables and arguments in transformations?Transformations dialog box consists of two different tables: one of arguments and the other of variables. While arguments refer to command line specified during batch processing, PDI variables refer to objects that are set in a previous transformation/job in the OS.27. How to configure JNDI for Pentaho DI Server?Pentaho offers JNDI connection configuration for local DI to avoid continuous running of application server during the development and testing of transformations.

Leading analyst firm recently stated in a research paper: open-source adoption increases, because it is often considered ‘good enough’. When cutting-edge functionalities are not of the essence, these offerings provide a robust and complete alternative. The functionality of Pentaho Data Integration (PDI) for example, has increased so rapidly in the last two years that it has become a major competitor for commercial ETL tools. Open-source ETL tools are worth considering If you combine the ‘good enough’ factor with an attractive price point and the support delivered by the vendors, open-source ETL is certainly worth considering. In the ETL tools comparison report there is a thorough evaluation of the most common open-source ETL tools listed like Talend, CloverDX, and Pentaho. Commercial ETL tools comparison In total, twenty ETL & Data Integration tools are sold commercially, meaning they aren’t open source. The best-known commercial ETL tools are Informatica PowerCenter, SAP Data Services, Microsoft SSIS, and IBM’s Information Server. Open source ETL tools comparison We have researched three ETL & Data Integration tools that have an open source license structure. Take note, this doesn’t mean that you don’t have to pay for the software and/or service, but some have interesting licensing structures. All the vendors of the three open source ETL tools have a paid enterprise product offering. The open source ETL tools are: CloverETL, Pentaho Data Integration (PDI), and Talend Open Studio.
