ORACLE TABLEAU 

Oracle and Tableau are both powerful tools commonly used in the field of data analytics and business intelligence. Here’s an overview of how they can be used together:

1. Oracle Database: Oracle is a widely used relational database management system (RDBMS) that stores and manages structured data. It provides a robust and scalable platform for storing and retrieving data. Oracle databases can collect, store, and manage large volumes of data from various sources.
2. Tableau: Tableau is a data visualization and business intelligence tool that allows you to create interactive and shareable dashboards, reports, and visualizations. It can connect to various data sources, including databases, spreadsheets, cloud services, and more, to help users analyze and understand their data.

Integration:

You can integrate Oracle with Tableau in several ways:

1. Direct Connection: Tableau has built-in connectors that allow you to connect directly to Oracle databases. You can connect to your Oracle database, import data into Tableau, and create visualizations based on that data.
2. Data Extraction: Tableau allows you to extract a subset of data from an Oracle database into its proprietary format (Tableau Data Extracts or .hyper files). This can improve performance and allow for more complex calculations within Tableau.
3. Custom SQL: Tableau provides the option to write custom SQL queries to retrieve data from Oracle databases. This can be useful when performing advanced data transformations or joining data from multiple tables.
4. Web Data Connector: You can create a custom Web Data Connector (WDC) to connect Tableau to Oracle databases through web services, APIs, or other data sources. This method provides flexibility in connecting to non-standard data sources.
5. ETL Tools: You can use Extract, Transform, and Load (ETL) tools like Oracle Data Integrator (ODI) or Talend to extract data from Oracle databases, transform it as needed, and then load it into Tableau for visualization.
6. Tableau Server and Tableau Online: If you’re using Tableau Server or Tableau Online, you can publish your Tableau dashboards and reports to these platforms, making them accessible to others within your organization. Users can interact with the dashboards without direct access to the Oracle database.
