3. What is MongoDB
 MongoDB (from "humongous") is an open source
document database written in C++.
 MongoDB in a nutshell
 Document-Oriented Storage (JSON Documents)
 JSON-style documents with dynamic schemas offer simplicity and
power.
 Full Index Support. Index on any attribute, just like you're used to.
 Rich, document-based query language.
 Map/Reduce
 Flexible aggregation and data processing.

4. The Jaspersoft MongoDB Query
Language
 The Jaspersoft MongoDB Query Language is a JSON-
style declarative language for specifying what data to
retrieve from MongoDB. The connector converts this
query into the appropriate API calls and uses the
MongoDB Java connector to query the MongoDB
instance.
 There are two types of queries supported:
 API driven queries: These queries rely on the mongo-java-driver support
provided to query MongoDB.
 Command driven queries: This queries allow the usage of MongoDB
Aggregation Framework operators

5. Connecting Jaspersoft to MongoDB
 Creating a JasperServer
Datasource
 Setting connection URL
mongodb://<SERVER>:<PORT>/<COLLECTION>
and (optional) authentication

6. API Driven Queries
Querying Mongo form Jasper
{
# The following parameter is mandatory.
collectionName : myCollection Details,
# The following parameters are optional
findQuery : { Details },
findFields : { Details },
sort : {Details},
mapReduce : {Details},
limit : int Details,
rowsToProcess : int Details
}

7. Command Driven Queries
Querying mongo form Jasper
{
runCommand : { Command body },
# The following parameter is optional
rowsToProcess : int Details
}
Using runCommand to access the MongoDB aggregation framework
{
runCommand : {
aggregate : COLLECTION_NAME,
pipeline : [ List of aggregation operations ]
}
}

8. Example Queries
Minimal
{ 'collectionName' : 'accounts’ }
Filtered and parameterized
{
'collectionName' : 'accounts',
'findQuery' : {
'status_date' : { '$gte' : $P{StartDate} },
'name' : { '$regex' : '^N', '$options' : '' }
}
}

9. Example Queries
Specify the fields returned and sort the results
{
'collectionName' : 'accounts',
'findFields' : {
'name':1,
'phone_office':1,
'billing_address_city':1,
'billing_address_street':1,
'billing_address_country':1
},
'sort' : {
'billing_address_country':-1,
'billing_address_city':1
}
}

10. Example Queries
Using the Aggregation
{
runCommand: {
aggregate : 'zips',
pipeline : [ { $group : { _id : '$state',
population: { $sum : '$pop'
}
}
},
{ $sort : { population : -1
}
}
]
}
