3 Install Mondrian Plugin

3.1 Install

Pre-requisites: Download and Install Eclipse version 3.x and the EMF&SDO version 2.x(required).

Install Mondrian Plugin 14


Download and unzip the mondrian-schema.zip into Eclipse installation directory, this will install theplugin. Download it from http://research.cip.cgiar.org/docs/downloads/ orhttp://sourceforge.net/projects/jpivot or <CD>:\Install\Pre-requisites\Windows

Start up eclipse and in the menu click on Help->About Eclipse Plattform->Plug-in Details. MondrianSchema Editor Plugin must appear in the list of installed plugins.

3.2 Test Plugin

The plugin is registered with the ".mondrian" file extension, this means you will have to rename TOMCAT_HOME\webapps\mondrian\WEB-INF\queries\Foodmart.xml into Foodmart.mondrian soEclipse can associate the file with the plugin.

If you prefere, download the file Foodmart.mondrian : http://research.cip.cgiar.org/docs/mondrian/FoodMart.mondrian

3.2.1 Create new "Simple" Project

Using the editor to create a new "Simple" proyect

Select a directory

http://research.cip.cgiar.org/docs/downloads/mondrian-schema-1.0.1.zip

http://sourceforge.net/projects/jpivot

http://research.cip.cgiar.org/docs/mondrian/FoodMart.mondrian



3.2.2 Open FoodMart.mondrian

Choose a project directory that contains Foodmart.mondrian. In the Package Explorer selectFoodmart.mondrian and open it.

Now the Eclipse workbench should look similar to the followind screenshot and you should be able toedit the Mondrian Schema

Install Mondrian Plugin 16


4 Create a simple cube

We're going to create a simple OLAP cube for passport data, for this we need to:

· Modify the source code of mondrian.jsp· Create a schema for the OLAP model with Eclipse

For this example we're using a sample database of potato from CIP



4.1 General overview

4.2 Copy database from CD

From <CD>:\examples\olapdb\ copy the Access database file "cippassportolap.mdb" to TOMCAT_HOME\webapps\mondrian\WEB-INF\queries\

or download from web: http://research.cip.cgiar.org/docs/downloads/examples_mondrian/cippassportolap.mdb

4.3 Create System ODBC

Create a new system ODBC with the name "cippassportolap" that refer to the Access database"cippassportolap.mdb", to select the file cippassportolap.mdb use de Select button.

http://research.cip.cgiar.org/docs/downloads/examples_mondrian/cippassportolap.mdb

Create a simple cube 18


4.4 Create a passport folder

Now you have to create a new folder, but this will be a back-up of mondrian folder located in TOMCAT_HOME/webapp, here we're giong to work



4.5 Modify mondrian.jsp

Windows

In TOMCAT_HOME\webapps\passport\web-inf\queries\mondrian.jsp you must to modify thecode, red code indentify the changes.

Note:"passport.xml" is the model OLAP schema.


<jp:mondrianQuery id="query01" jdbcDriver="sun.jdbc.odbc.JdbcOdbcDriver"jdbcUrl="jdbc:odbc:cippassportolap" catalogUri="/WEB-INF/queries/passport.xml">

select {[Measures].[Accs]} ON columns, Union({[FAO].[All FAO]}, [FAO].[All FAO].Children) ON rowsfrom [passport]

</jp:mondrianQuery>




Linux

In opt/lampp/lib/tomcat/webapp/passport/WEB-INF/queries/mondrian.jsp you must to modify thecode, red code indentify the changes.


<jp:mondrianQuery id="query01" jdbcDriver="com.mysql.jdbc.Driver"jdbcUrl="jdbc:mysql://localhost/cippassportolap?user=foodmart&passport=foodmart"catalogUri="/WEB-INF/queries/passport.xml">

select {[Measures].[Accs]} ON columns, Union({[FAO].[All FAO]}, [FAO].[All FAO].Children) ON rowsfrom [passport]

</jp:mondrianQuery>


4.6 Create a new Schema using Eclipse plugin

4.6.1 Create a simple project

First of all, you have to shutdown Tomcat, then you have to create a new simple project in yourworkspace, in this example the proyect is called passport_olap



4.6.2 Create a *.mondrian file

After to create the project if doesn't appear a file named passport.mondrian you must create the file

Now you have to open passport.mondrian with text editor form :



Now in the text editor wrtite the folowing code to create a root schema

<?xml version="1.0"?> <Schema name="Passport">

</Schema> />

Now using the Mondrian editor form to check if the schema has created succesfuly:



You must see a tree like this:

4.6.3 Create root schema

Then you have to open passport.mondrian with Mondrian Model Editor, here you can create theschema, cubes, dimensions,etc.



4.7 Adding measures & dimensions

4.7.1 Example 1

For the example, we're going to create a cube with one dimension and one measure

4.7.1.1 Step to modify schema

4.7.1.1.1 Create cube "Passport"

After to create a root schema, create the cube "Passport" and add the properties.



4.7.1.1.2 Create the fact table "passport_FactTable"

Create the fact table "passport_FactTable"



4.7.1.1.3 Create the dimension "FAO"

Create the dimension "FAO".

4.7.1.1.3.1 Create the hierarchy for "FAO" dimension

Create the hierarchy for FAO dimension



After to create the hierarchy of dimension, you have to create the table of the dimension



After to create the table of dimension, you have to create the level of the hierarchy.



4.7.1.1.4 Create the measure "Accs"

Create the measure "Accs" to count the number of germplasm.



4.7.1.2 Final code view

And this cube has the following code.

In this case we have one cube, three dimensions, three levels and two measures


We will continue modified the example 4, we have a schema with one cube, three dimension andtwo measures. Now we will create a new level of the "Taxonomy" dimension.




4.7.5.1.1 Create level species of hierarchy





To download the example V Click Here(http://research.cip.cgiar.org/docs/downloads/examples_mondrian/exercise5.txt)or from <CD>:\Examples\Schemas

NOTE: that the example V is the same to passport.xml





4.7.6 Example6

For one cube with three levels and three dimensions where the [Location] dimension is a"snowflake dimension" with two tables [Country] and [Region] .

4.7.6.1 Create the dimension "location" with two tables

Create the dimension "location"



4.7.6.1.1 Create the hierarchy for "Location" dimension

Create the hierarchy for "Location" dimension the Foreing Key CountryID joins the FactTable with thedimension.

4.7.6.1.1.1 Create Join for "Location" dimension

After create the hierarchy, you have to create the join for conect the tables of the dimension:[Country] and [Region].



1.- Table [Country]



2- Table [Region]



4.7.6.1.1.2 Create levels of hierarchy

Create the levels of the hierarchy: [Continent], [Region] and [Country]



1.- Level: [Continent]

2.- Level: [Region]



3.- Level: [Country]

4.7.7 Example 7

4.7.7.1 Create the dimension "location" with three tables

Create the dimension "location"




4.7.7.1.1 Create the hierarchy for "Location" dimension

Create the hierarchy for "Location" dimension the Foreing Key CountryID joins the FactTable with thedimension.



4.7.7.1.1.1 Create First Join for "Location" dimension

After create the hierarchy, you have to create the join to conect the [Continent] table with the two tablejoin: [Region] and [Country]



Now we are going to create the join for conect the tables of the dimension: [Country] and [Region].



1.- Table [Country]

2.- Table [Region]



4.7.7.1.1.2 Create levels of the hierarchy

Create the levels of the hierarchy: [Continent], [Region] and [Country]

1.- Level: [Continent]



2.- Level: [Region]

3.- Level: [Country]

4.8 Publish schema

When you end the edition of the *.mondrian file, you must rename changing the extention from.mondrian to .xml.

After you change the *.xml file, copy this file at TOMCAT_HOME\webapps\mondrian\web-inf\queries,then you have to shutdown Tomcat and then start Tomcat again to load Mondrian and see the changesin the file.




4.9 Create Job Script to Fill Database

The job script is to copy data from relational databases or flat files(Excel, Text) to OLAP database.

This script can be developed in Java, Visual Basic , PHP in the language you prefer.

The script must be scheduled to run every day automatically.
