The repository stores the information you provide to define the analysis client connection.ĭefine entry points for analysis of the cube data, known as OLAP views in Jaspersoft OLAP. Optionally, define data level security for the cube with access grants that limit users to only the data they are allowed to see, based on their roles and user profile information. The Mondrian Technical Guide gives details of schemas and their options.Ĭreate an analysis client connection that includes your schema and a database connection. The Jaspersoft OLAP Schema Workbench enables you to develop, validate, and test schemas against the database. The Jaspersoft OLAP engine uses the schema to interpret the database and perform OLAP queries. Identify facts or measures (the values to summarize) and dimensions (divisions of the measures – for example, dividing time into weeks, months, and years) in the cube database.ĭefine a Jaspersoft OLAP schema, mapping logical facts and dimensions onto the physical database. To improve performance, use an extract, transform, and load (ETL) process: extract information from one or more data sources, integrate and transform the data, and load the result into the separate cube database. Note that using existing transactional databases may be inefficient with large amounts of data. Store cube data in a relational database and use an OLAP schema file to define the cubes. To implement and maintain Jaspersoft OLAP: 1. XML/A uses a web services architecture, and transmits MDX queries using the SOAP protocol. In a distributed computing environment, XML for Analysis (XML/A) is the standard for accessing OLAP data sources remotely. The de facto standard for OLAP query languages is MDX many analysis applications use it. Jaspersoft OLAP Professional and Enterprise include an improved JPivot user interface (as compared to JPivot or JasperReports Server Community Edition). JPivot, an open source web-based OLAP user interface, enables users to display and navigate Mondrian’s results. Jaspersoft OLAP is based on an open source ROLAP server called Mondrian. This is sometimes referred to as Relational OLAP (ROLAP). In a relational database implementation of online analytical processing (OLAP), the entities reside in relational tables. Jaspersoft OLAP lets you analyze data organized into a hierarchical dimensional model, which has cubes and dimensions as its primary entities.
