Jaspersoft OLAP

Minor enhancements and engine updates over the years

Not-so-secret work underway to query the powerfulOLAP engine (Mondrian) from the Jaspersoft ad hocuser interface

What makes the engine powerful?

Answer: MDX

Domain Capabilities and Limitations

Domain: Database schema

represented in XML

XML converts to SQL defaultSQLGenerator

oracleSQLGenerator postgreSQLGenerator

sqlserverGenerator MS SQL Server

Ingres

db2SQLGenerator

mmxSQLGenerator

custom



18/48


XML snippet from a domain:

join store store on (sales_fact_1997.store_id ==

store.store_id)

Notice `back-ticks` were generated for MySQL in this

example


inner join `store` on (`sales_fact_1997`.`store_id` = `store`.`store_id`)


19/48


Sample generated by SQLGenerator

Query

select

store.store_type as store_store_type,

sum(sales_fact_1997.store_sales) as newSet1_store_sales_Sum


from

sales_fact_1997 inner join store on

(sales_fact_1997.store_id = store.store_id)

where

store.store_country = 'USA'

group by

store.store_type

order by

store_store_type


20/48


The database and database schema matter a lot

Complex join paths => complex queries => long queries

are optimized for rapid, small INSERTS, not SELECTS



21/48

Domain Tips

You can get a domain from a star schema in minutes

Columnar databases are well worth evaluating

Staging data Using a Topic (next up) that runs an optimized stored procedure

Not shown: Derived Tables run as sub-queries; this may

impact performance

After Topics: performance tracking tips



22/48

Analyzing Data From Any Source: Topics

Topics were Jaspersofts first data source for ad hocreport design



23/48

Topics are JasperReport units stored in the Topics folder




24/48

JasperReports Server lists all reports in this folder in theTopics panel




25/48

Why is this great?

You can use ANY query, ANY data source


Custom queries (hibernate, Hadoop, web services, etc.)

Stored procedures, etc.



26/48

Topics

Queries are extracted from

JasperReports (JRXML) files

The query language only needs tobe registered with JasperReports

Domains

Queries are built on-demand by

the SQLGenerator

The SQLGenerator converts XML(the Domain definition) to SQL at


erver

Topics can use any data source,

including custom data sources

The query is pre-defined / canned

run- me

Domains require a JDBC or JNDI

data source

Domains can make many morefields available to users


Tip: use Domains for relational databases; best with star schemasTip: use Topics for non-SQL data sources or complex queries

Data for Jaspersoft OLAP

Need a star schema Model against an existing database

Create a new database optimized for OLAP operations OLAP environment characteristics

Select/read queries with grouping across large data sets

Multiple data sources may be needed to get the data needed foranalysis: need to consolidate

Technology options Can your transactional environment take it?

Can your RDBMS take it? Or is it not efficient? Or cost effective? Look at different RDBMS options within your current environment, or

analytic databases

Deploying OLAP, Step 2In JasperReports Server

1. Create a JDBC or JNDI data source (if not alreadyavailable)

2. Upload the OLAP Schema3. Create an OLAP Client Connection

1. Type: Mondrian

2. Select the OLAP Schema (from step 2)

3. Select the JDBC or JNDI data source (from step 1)

4. Do not link an Access Grant (until youre expert)

4. Create an OLAP View1. Type: Mondrian

2. Select the Mondrian Client Connection (from step 3)

3. Paste your MDX query string remove the semicolon at the end

MDX Query Profiling

Analysis Options > Performance Profiling

Good for testing, developing better MDX queries

See: JasperAnalysis Ultimate Guide 3.7, Section 5.3.2Profiling Performance

Note: Auditing is different. See the chapter on Auditing inthe JasperReports Server Administrator Guide.
