Use the CData Connector for MongoDB in APOS Live Data Gateway to build Semantic Layer Views for MongoDB data.
APOS Live Data Gateway (LDG) is a data connection and data transformation solution that enables live data connectivity and expanded data source options for SAP Analytics Cloud and other SAP solutions. When paired with CData Connectors, users can build semantic layer views for live MongoDB data, enabling real-time analytics on MongoDB just like working with a relational database.
With built-in optimized data processing, the CData Connector offers unmatched performance for interacting with live MongoDB data. When you issue complex SQL queries to MongoDB, the driver pushes supported SQL operations, like filters and aggregations, directly to MongoDB and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze MongoDB data using native data types.
About MongoDB Data Integration
Accessing and integrating live data from MongoDB has never been easier with CData. Customers rely on CData connectivity to:
- Access data from MongoDB 2.6 and above, ensuring broad usability across various MongoDB versions.
- Easily manage unstructured data thanks to flexible NoSQL (learn more here: Leading-Edge Drivers for NoSQL Integration).
- Leverage feature advantages over other NoSQL drivers and realize functional benefits when working with MongoDB data (learn more here: A Feature Comparison of Drivers for NoSQL).
MongoDB's flexibility means that it can be used as a transactional, operational, or analytical database. That means CData customers use our solutions to integrate their business data with MongoDB or integrate their MongoDB data with their data warehouse (or both). Customers also leverage our live connectivity options to analyze and report on MongoDB directly from their preferred tools, like Power BI and Tableau.

Getting Started
Download and Install the Connector Files
In order to access MongoDB data through the APOS Live Data Gateway, you will need to download the connector files from APOS and install them on the machine hosting the Live Data Gateway. An APOS representative can deliver the necessary files.
- Install the CData DLL file (System.Data.CData.MongoDB.dll) to the APOS Live Data Gateway installation directory (C:\Program Files\Live Data Gateway\Admin\ by default).
- Install the CData JAR file (cdata.jdbc.mongodb.jar) to the ConnectionTest_lib folder in the installation directory (C:\Program Files\Live Data Gateway\Admin\ConnectionTest_lib\ by default).
- Install the CData JAR file (cdata.jdbc.mongodb.jar) to the lib folder in the Web UI installation directory (e.g.: C:\LDG_WebUI\lib\)
Configuring the MongoDB Connection String
Before establishing the connection to MongoDB from the APOS Live Data Gateway, you need to configure the MongoDB JDBC Connection String.
Built-in Connection String Designer
For assistance in constructing the JDBC Connection String, use the connection string designer built into the MongoDB JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.mongodb.jar
Fill in the connection properties and copy the connection string to the clipboard.
Set the Server, Database, User, and Password connection properties to connect to MongoDB. To access MongoDB collections as tables you can use automatic schema discovery or write your own schema definitions. Schemas are defined in .rsd files, which have a simple format. You can also execute free-form queries that are not tied to the schema.

Your connection string will look similar to the following:
jdbc:MongoDB:Server=MyServer;Port=27017;Database=test;User=test;Password=Password;
Connecting to MongoDB & Creating a Semantic Layer View
After installing the connector files and configuring the connection string, you are ready to connect to MongoDB in the Live Data Gateway Admin tool and build a semantic layer view in the Live Data Gateway Web UI.
Configuring the Connection to MongoDB
- Log into your APOS Live Data Gateway Manager
- If you haven't already, update your APOS LDG license file
- Click File -> Configurations
- Click on the "..." Menu for the License
- Select the license file from the APOS team that includes your CData Connector license
- In the APOS Live Data Gateway Manager, click "Add"
- In the APOS Live Data Gateway On the Connection tab, configure the connection:
- Set Data Source to "Database"
- Set Database to "CData Drivers"
- Set Database CData Drivers to "MongoDB"
- Set Connection String to the connection string configured earlier (e.g.:
jdbc:MongoDB:Server=MyServer;Port=27017;Database=test;User=test;Password=Password;
- Set Driver Class to "cdata.jdbc.mongodb.MongoDBDriver" (this should be set by default)
- Click Test Connection
- Click Save
- Give your connection a unique prefix (e.g. "mongodb")
- Highlight the newly created connection and click File -> "Approve Users For Web UI"
- Approve the appropriate DB users to create views and click "Save"
At this point, we are ready to build our semantic layer view in the Live Data Gateway Web UI.
Creating a Semantic Layer View
- In your browser, navigate to the APOS Live Data Gateway Portal
- Select a Connection (e.g. "mongodb")
- Set User Name and Password to the User and Password properties for MongoDB.
- Click "Login"
- Once connected, click "Semantic Layer" to create a new semantic layer view
- Click "New Semantic Layer View"
- Set the Semantic Layer View Prefix and Semantic Layer View Name
- Click "Step 2"
- Select the table(s) and column(s) you wish to include in your view
- Click "Step 3"
- Select the Measures from the available table columns
- Click "Step 5" (we skipped the "Extra Dimensions" step)
- Add any Variable Prompts
- Click "Step 6"
- Define any Table Joins
- Click "Review"
- Review you semantic layer view and click "Save"
With the Semantic Layer View created, you are ready to access your MongoDB data through the APOS Live Data Gateway, enabling real-time data connectivity to MongoDB data from SAP Analytics Cloud and other SAP solutions.
