Hướng dẫn mongodb bi connector dsn

Prerequisites

Before creating a DSN, you should:

Procedure

• MongoDB installed on your local system. Download the latest production release of MongoDB from the MongoDB Download Center and install it. For detailed instructions, see Install MongoDB.

• MongoDB Connector for BI installed on your local system. Download the latest production release of BI Connector from the MongoDB Download Center and install it. For detailed installation instructions, see Install BI Connector On Premises.

• The MongoDB BI Connector ODBC Driver installed on your local system.

• Visual C++ Redistributable for Visual Studio 2015

• A BI tool of your choice, such as Power BI or Qlik Sense.

If mongod is not already running on your local system, start it from the command line in the MongoDB program directory. You can create the default data directory at C:\data\db or specify a different directory with the --dbpath option.

"C:\Program Files\MongoDB\Server\3.6\bin\mongod.exe"

Make sure your MongoDB instance has at least one collection with some data for testing purposes. A sample dataset with United States ZIP code information (3.2 MB) is available at media.mongodb.org/zips.json.

Note

To save the ZIP code dataset directly to disk, right click on the link and select "Save Link As..." This tutorial assumes that the saved file is in the directory C:\data.

Import the dataset into MongoDB. The following command imports the zips.json file into a collection named zips in a database named test:

"C:\Program Files\MongoDB\Server\3.6\bin\mongoimport.exe" --db test --collection zips --file "C:\data\zips.json"

See the MongoDB manual for help with mongoimport, the mongo shell program, and CRUD operations.

Start a mongosqld process from the command line in the BI Connector program directory.

"C:\Program Files\MongoDB\Connector for BI\2.3\bin\mongosqld.exe"

With no command line options, mongosqld generates a schema from all the user-accessible collections in your MongoDB instance. For more information about specifying database namespaces for BI Connector to work with, see the mongosqld reference page.

If mongosqld starts correctly, the last line of on-screen output declares the namespaces it has found for its schema. For example, the following output indicates that mongosqld started correctly and sampled the zips namespace.

[schemaDiscovery] mapped schema for 1 namespaces: "test" (1): ["zips"]

Create a System DSN by following instructions in the tutorial. For the purposes of this local test installation you can leave the User, Password and Authentication fields blank, because mongosqld is running without the --auth option.

When you press the Test button you should see the Connection Successful result.
