Configure Oracle Data Sources in NCC Portal

This article describes how to connect and manage Oracle data sources in the NCC Portal, following Microsoft Learn Fabric documentation style.

Prerequisites

Before you start, make sure you have the following details:

  • Server name
  • Database name
  • Username (or Client ID)
  • Password (or Client Secret)

Step 1: Connect to Oracle Database

To connect your Oracle Database to your Fabric tenant:

  1. Visit Connect to Oracle Database and follow the instructions to create a new connection.
  2. If required, create a private endpoint.
  3. Name your connection using the CON_NCC prefix. This naming convention helps ensure visibility and manageability within the NCC Portal.

Step 2: Register a Data Source

  1. In the NCC Portal, navigate to Tenant Settings > Data Sources.
  2. Select Add DataSource.
  3. Complete the following fields:
Field Description Example/Default Value
Name Name of the source Oracle database
Data Source Type Type of data source ORACLE
Namespace Prefix for storing data in Lakehouses
Code Identifier for pipelines ORACLE_01
Description Description of data source
Connection Name of the connection in Fabric - Set in previous step
Environment NCC environment for the data source Development

Step 3: Create a Landing Zone Entity

  1. Go to Landing Zone Entities.
  2. Select New Entity.
  3. Fill in the required details:
Field Description Example/Default Value
Pipeline Not used
Data Source Data source for connection - Set in previous step
Source schema Schema name in Oracle
Source name Table or view name in Oracle
Incremental Extract data incrementally False
Has encrypted columns Indicate if the table contains sensitive data False
Entity value Optional. Entity values reference
Lake house Lakehouse for storing data LH_Data_Landingzone
File path File path for data storage Is filled automatically
File name File name for data storage Is filled automatically
File type Expected file type Parquet

  • Click here to apply data encryption to sensitive data.

Step 4: Create a Bronze Zone Entity

  1. Go to Bronze Zone Entities.
  2. Select New Entity.
  3. Enter the following information:
Field Description Example/Default Value
Pipeline Orchestrator pipeline for parsing PL_BRZ_COMMAND
Landing zone entity Landing zone entity to be parsed - Set in previous step
Entity value Optional. Entity values reference
Column mappings Optional. Column mapping info
Lake house Lakehouse for storing data LH_Bronze_Layer
Schema Schema for storing data dbo
Name Table name for storing data Is filled automatically
Primary keys Unique identifier fields (Case sensitive)

NOTE:
While this connector can copy data types from source to destination, some types are cast to DECIMAL because Oracle precision may exceed Parquet file limits. The following data types are converted to DECIMAL: (NUMBER, DECIMAL, FLOAT).

Step 5: Create a Silver Zone Entity

  1. Go to Silver Zone Entities.
  2. Select New Entity.
  3. Provide the following details:
Field Description Example/Default Value
Pipeline Orchestrator pipeline for parsing PL_SLV_COMMAND
Bronze layer entity Bronze layer entity to be parsed - Set in previous step
Entity value Optional. Entity values reference
Lake house Lakehouse for storing data LH_Silver_Layer
Schema Schema for storing data dbo
Name Table name for storing data Is filled automatically
Columns to exclude Comma-separated columns to exclude (Case sensitive)
Columns to exclude from history Comma-separated columns to exclude from comparison (Case sensitive)

Example

The company InSpark has an Oracle database connection in Fabric named NCC_ORACLE_SALES to the database InSpark_Sales. In this database, there is a table total_sales in the schema dbo that the company wants to extract. The configuration would be as follows:

Data Source

Field Value
Name InSpark_Sales
Data Source Type ORACLE
Namespace InSpark_Sales
Code ORACLE_01
Description Oracle connection to InSpark_Sales
Connection NCC_ORACLE_SALES
Environment Development

Landing Zone Entity

Field Value
Pipeline PL_LDZ_COPY_FROM_ORACLE_01
Data Source InSpark_Sales
Source schema dbo
Source name total_sales
Incremental False
Entity value
Lake house LH_Data_Landingzone
File path InSpark_Sales
File name total_sales
File type Parquet

Bronze Zone Entity

Field Value
Pipeline PL_BRZ_COMMAND
Landing zone entity InSpark_Sales/total_sales
Entity value
Column mappings
Lake house LH_Bronze_Layer
Schema dbo
Name total_sales
Primary keys id

Silver Zone Entity

Field Value
Pipeline PL_SLV_COMMAND
Bronze layer entity dbo.total_sales
Entity value
Lake house LH_Silver_Layer
Schema dbo
Name total_sales
Columns to exclude
Columns to exclude from history
