Data Governance with Document Validation

Implement data governance without

sacrificing agility that comes from dynamic

schema

• Enforce data quality across multiple teams and

applications

• Use familiar MongoDB expressions to control

document structure

• Validation is optional and can be as simple as a

single field, all the way to every field, including

existence, data types, and regular expressions

Document Validation Example

The example on the left adds a rule to the

contacts collection that validates:

• The year of birth is no later than 1994

• The document contains a phone number and / or

an email address

• When present, the phone number and email

addresses are strings

“Rocket.Chat and our other applications need to be able to quickly access various types of data to provide a seamless solution for our users.

With MongoDB 3.2, we will now be able to implement the data governance we’re seeking, without sacrificing agility that comes from dynamic schema. The newfound ability to use familiar MongoDB expression syntax to control document structure, rather than learning a whole new language or process, is key for us.”

Gabriel EngelFounder and CEORocket.Chat

Enhancements for your mission-critical appsMore improvements in 3.2 that optimize the

database for your mission-critical

applications

Tools for Users Across Your Organization

For Business Analysts & Data Scientists

MongoDB 3.2 allows business analysts and

data scientists to support the business with

new insights from untapped data sources

• MongoDB Connector for BI

• Dynamic Lookup

• New Aggregation Operators & Improved Text

Search

Only 0.5% of data is analyzed

Source: IDC

MongoDB Connector for BIVisualize and explore multi-dimensional

documents using SQL-based BI tools. The

connector does the following:

• Provides the BI tool with the schema of the

MongoDB collection to be visualized

• Translates SQL statements issued by the BI tool

into equivalent MongoDB queries that are sent to

MongoDB for processing

• Converts the results into the tabular format

expected by the BI tool, which can then visualize

the data based on user requirements

“We are thrilled to enable Tableau users, who traditionally work with their relational data, to fully integrate the multi-structured data stored in the database powering modern applications via the new MongoDB BI Connector”

Jeffrey FengProduct ManagerTableau Software

Dynamic LookupCombine data from multiple collections with

left outer joins for richer analytics & more

flexibility in data modeling

• Blend data from multiple collections for analysis

• Higher performance analytics with less

application-side code and less effort from your

developers

• Executed via the new $lookup operator, a stage in

the MongoDB Aggregation Framework pipeline

“I am most excited by the dynamic lookups coming in MongoDB 3.2. The ability to more easily join customer data with 3rd-party data feeds gives us more flexibility in data modeling, and simplifies the real-time analytics we rely on to constantly improve our value to our customers.”

To support MongoDB 3.2, we jointly-developed an integration between MongoDB Ops Manager and New Relic APM, Insights, and Plugins. These integrations mean MongoDB health can now be monitored alongside the rest of the application estate.".”

Cooper MarcusSenior Product ManagerNew Relic.

Query Perf. Visualizations & OptimizationFast and simple query optimization with the

new Visual Query Profiler

• Query and write latency are consolidated and

displayed visually; your ops teams can easily

identify slower queries and latency spikes

• Visual query profiler analyzes the data it displays

and provides recommendations for new indexes

that can be created to improve query performance

• Ops Manager and Cloud Manager can automate

the rollout of new indexes, reducing risk and your

team’s operational overhead

“I’m excited by the availability of Visual Query Profiler in Ops Manager & Cloud Manager. It helps us tremendously improve the performance of our database by identifying queries that are slowing us down and provides recommendations for new indexes -- which it can then build through a rolling index build.”

Daniel RubioDirectorMondo Sports Ltd

Refine with Partial Indexes

Balance delivering good query performance

while consuming fewer system resources

• Specify a filtering expression during index creation

to instruct MongoDB to only include documents

that meet your desired conditions

Conceptual Model of Aggregation Framework

Start with the original collection; each record

(document) contains a number of shapes (keys),

each with a particular color (value)

• $match filters out documents that don’t contain a

red diamond

• $project adds a new “square” attribute with a value

computed from the value (color) of the snowflake

and triangle attributes

Conceptual Model of Aggregation Framework

• $lookup performs a left outer join with another

collection, with the star being the comparison key

• Finally, the $group stage groups the data by the

color of the square and produces statistics for

each group
