Begin by ensuring your Oracle Database is properly set up and running. Install necessary Oracle Database software and create the required user accounts and tablespaces. Make sure you have access permissions to create tables and insert data.

Define the structure of the target table in the Oracle Database according to the data you plan to fetch from the News API. Use SQL commands to create the table with appropriate data types that match the API's response structure. For example:
```sql
CREATE TABLE news_articles (
article_id NUMBER PRIMARY KEY,
title VARCHAR2(500),
description VARCHAR2(2000),
published_at DATE,
source_name VARCHAR2(100)
);
```

Write a script using a programming language like Python, Java, or Node.js to make HTTP requests to the News API. Use the API key and endpoint provided by the News API documentation to fetch news articles. Parse the JSON response to extract relevant fields.

In your script, parse the JSON response from the API into individual data components. Transform the data as necessary to match the data types and constraints of your Oracle table. For example, converting date strings to Oracle's DATE format.

Use a database connectivity library compatible with your programming language (such as cx_Oracle for Python or JDBC for Java) to establish a connection to your Oracle Database. Ensure that your script includes the correct connection string, username, and password.

Iterate over the parsed API data and construct SQL `INSERT` statements. Use the database connection to execute these statements, inserting the data into your Oracle table. Implement error handling to manage any exceptions or data constraints violations during the insertion process.

To keep your Oracle Database updated with the latest news data, schedule your script to run at regular intervals using a cron job (Linux) or Task Scheduler (Windows). Ensure the script handles duplicate records or updates as needed, perhaps by implementing logic to check for existing records before inserting new ones.

By following these steps, you can effectively move data from a News API to an Oracle Database without relying on third-party connectors or integrations.
