Interview Questions and Answers

You can find documentation and support on the Eclipse BIRT website, the Actuate website (if using Actuate extensions), and various online forums and communities.

Actuate BIRT supports JavaScript scripting, which can be used to customize report behavior, perform calculations, and format data.

Best practices include using clear and concise report layouts, optimizing data set queries for performance, using parameters to allow for report customization, and thoroughly testing reports.

You can use try-catch blocks in script expressions to handle exceptions and log errors. Also, BIRT provides mechanisms for displaying error messages in reports.

Report bursting is the process of generating multiple report instances from a single report design, where each instance is targeted to a specific user or group based on data values.

You can schedule reports using the BIRT iHub or a third-party scheduler. The scheduler will automatically generate and distribute reports based on a defined schedule.

The BIRT Runtime environment is a collection of Java libraries that are needed to execute BIRT report designs. It is typically deployed in a web server or application server.

You typically deploy the .rptdesign file and the necessary BIRT Runtime libraries to a web server (e.g., Tomcat, Jetty) and configure a servlet to handle report requests.

You can define parameters in the BIRT Designer and use them in data set queries or report expressions. Parameters allow users to customize the report output.

You drag a chart element onto the report layout and configure its properties, including the chart type, data series, axes, and labels.

Actuate BIRT provides various formatting options, including font styles, colors, borders, and number formats, which can be applied to report elements.

A BIRT report design file (usually with a .rptdesign extension) is an XML file that defines the structure, layout, data sources, and data bindings for a BIRT report.

You create a data source object in the BIRT Designer, specifying the database connection information (e.g., driver class, URL, username, password).

A data set represents the data that is retrieved from a data source for use in a report. It typically involves a SQL query or a procedure call.

Key features include a visual report designer, data connectivity to various sources, report scheduling, report bursting, interactive reporting, and a robust API for customization.

Actuate BIRT can create various types of reports, including tabular reports, charts, cross-tab reports, master-detail reports, and interactive dashboards.

Actuate BIRT supports a wide range of data sources, including relational databases (e.g., MySQL, Oracle, SQL Server), flat files (CSV, TXT), XML files, and web services.

Installation typically involves downloading the BIRT Designer or BIRT Runtime environment, configuring database connections, and setting up the necessary Java environment variables.

You use the BIRT Designer, a graphical IDE, to drag and drop data elements, charts, and other components onto a report layout. You configure data bindings and formatting options.

Actuate BIRT is a Java-based open-source reporting system and reporting tool platform. It allows users to create pixel-perfect reports from a variety of data sources.

A reporting application goes through three stages: authoring, managing, and delivery.

In general Reporting Services components are of the following types: Report Builder, Report Designer, Report Manager, Report Server, Report server database and Data sources.

You can export the reports to various formats once you have run your report. Tabular reports can be exported to spreadsheets, Text, PDF and HTML. Graphs can also be exported to image files or documents.

BI applications support various activities, such as decision support systems, online analytical processing, querying and reporting, forecasting and data mining, and statistical data analysis.

There are 4 key areas where report generation slowdown may occur: Data refresh, Model calculations, Visualization rendering, Everything else

The database schema of a database is it's structure described in a formal language supported by the database management system (DBMS). The term \"schema\" refers to the organization of data as a blueprint of how the database is constructed (divided into d

A data-driven subscription provides a way to use dynamic subscription data that is retrieved from an external data source at run time. A data-driven subscription can also use static text and default values that you determine when the subscription is defin

A: Universe is a semantic layer that maps complex data into descriptive business terms used across the organization, such as product, customer, region, revenue, margin or costs. This layer resides between an organization's database and the end-user.

OLTP (Online transaction processing) captures, stores, and processes data from transactions in real-time. OLAP (Online analytical process) uses complex queries to analyze aggregated historical data from OLTP systems.

Data Warehouse System is a system used for reporting and data analysis, and is considered a core component of business intelligence. Data Warehouses are central repositories of integrated data from one or more disparate sources.

Slicing and Dicing is about breaking down a body of information into smaller pieces, or analyzing it from various points of view so that you can better understand it. In data analysis, the term usually means a systematic reduction of smaller sections or v

Data masking or data scrambling or data anonymization is the process of replacing sensitive information copied from production databases to test non-production databases with realistic, but scrubbed (eg *, #), data based on masking rules. Sometimes Data

Canned reports, Ad hoc and Batch reports.

Ad hoc reporting is a report created for a one-time-use. A reporting tool can make it possible for anyone in an organization to answer a specific business question and present that data in a visual format. Canned reports are preformatted reports that are

Steps to create parameters to dynamically change what you see, and even sort by measurements that do not even have to be seen.

Step 1: Create your first parameter.

Step 2: Create a table calculation to link your parameter to measures.

TRUNCATE always removes all the rows from a table, leaving the table empty and the table structure intact while DELETE may remove conditionally if the where clause is used. The rows deleted by TRUNCATE TABLE statement cannot be restored and you can not sp

The traditional database stores information in a relational model and prioritizes the transactional processing of the data. This is known as an OLTP database. Data warehouses prioritize and gives importance to analysis, and are known as OLAP databases.
