Mastering High-Frequency Data Extraction and Ingestion from Oracle Fusion SaaS to OCI

Integrating Oracle Fusion SaaS Applications with Oracle Cloud Infrastructure (OCI) enables businesses to leverage the best of both worlds—advanced SaaS functionalities for enterprise resource planning (ERP), human capital management (HCM), and customer relationship management (CRM), along with the robust, scalable cloud computing capabilities of OCI. High-frequency data extraction and ingestion are crucial for real-time analytics, reporting, and data warehousing needs. This article explores a comprehensive strategy to set up and implement this integration, with practical examples and code snippets to guide you through the process.

Prerequisites

• Access to Oracle Fusion SaaS Applications with the necessary permissions to extract data.
• An active OCI account with permissions to create and manage resources such as Object Storage, Data Flow, and Oracle Autonomous Database (ADB).
• Familiarity with OCI CLI, SDKs, or Console for resource management.
• Basic understanding of REST APIs for data extraction from Oracle Fusion SaaS.

Strategy Overview

The integration process involves extracting data from Oracle Fusion SaaS Applications at a high frequency and ingesting it into OCI for further processing and analysis. This can be achieved through the following steps:

1. Data Extraction from Oracle Fusion SaaS: Utilize Oracle Fusion SaaS REST APIs to programmatically extract data.
2. Data Storage on OCI Object Storage: Temporarily store the extracted data in OCI Object Storage, acting as a staging area.
3. Data Ingestion into ADB or Data Lake: Ingest data from Object Storage into Oracle Autonomous Database or a Data Lake on OCI for analysis and reporting.

Step 1: Data Extraction from Oracle Fusion SaaS

Oracle Fusion SaaS offers REST APIs to access its applications’ data. You can use these APIs to extract data at the desired frequency. The key is to authenticate and make API calls to extract data systematically.

Authentication

First, obtain an authentication token using your Oracle Fusion SaaS credentials. This token will be used in subsequent API calls.

curl -X POST https://<FUSION_SaaS_URL>/oauth2/v1/token \
-d "grant_type=client_credentials&client_id=<CLIENT_ID>&client_secret=<CLIENT_SECRET>" \
-H "Content-Type: application/x-www-form-urlencoded"

Data Extraction

With the authentication token, make API calls to extract data from specific Fusion SaaS modules. For example, to extract employee data from HCM:

curl -X GET https://<FUSION_SaaS_URL>/hcmRestApi/resources/latest/emps \
-H "Authorization: Bearer <ACCESS_TOKEN>"

Extract data at your required frequency by scheduling these API calls using cron jobs or OCI Functions for automation.

Step 2: Data Storage on OCI Object Storage

After extracting data, store it in OCI Object Storage. Use the OCI CLI or SDKs to upload the data.

oci os object put --bucket-name <BUCKET_NAME> --file <FILE_TO_UPLOAD> --name <OBJECT_NAME>

Ensure your bucket is private to maintain data security and compliance.

Step 3: Data Ingestion into Oracle ADB or Data Lake

Finally, ingest the data from Object Storage into Oracle Autonomous Database or a Data Lake on OCI for analysis.

Ingesting into Oracle ADB

Use Oracle Data Pump or SQL*Loader for efficient data loading into ADB. For automated ingestion, consider using OCI Data Flow for executing Apache Spark jobs that read from Object Storage and write to ADB.

Sample Spark Job for Data Ingestion

Here’s a simple example of a Spark job that reads JSON data from Object Storage and writes it into an Oracle ADB table.

val df = spark.read.json("oci://<BUCKET_NAME>@<NAMESPACE>/path/to/json/files/")
df.write
  .format("jdbc")
  .option("url", "jdbc:oracle:thin:@<ADB_CONNECTION_STRING>")
  .option("dbtable", "<TARGET_TABLE>")
  .option("user", "<USERNAME>")
  .option("password", "<PASSWORD>")
  .save()

Deploy this Spark job in OCI Data Flow and schedule it as needed to ingest data into ADB.

Conclusion

Integrating Oracle Fusion SaaS Applications with OCI for high-frequency data extraction and ingestion opens up a plethora of opportunities for real-time analytics and decision-making. By following the steps outlined in this guide, organizations can set up a reliable, scalable integration pipeline that leverages the strengths of both Oracle Fusion SaaS and OCI. Remember to monitor the integration process and optimize the data flow as needed to ensure efficient operation and compliance with data governance policies.
