How to Visualize Oracle Financials Cloud Data in Python with pandas

The rich ecosystem of Python modules lets you get to work quickly and integrate your systems more effectively. With the CData Python Connector for Oracle Financials Cloud, the pandas & Matplotlib modules, and the SQLAlchemy toolkit, you can build Oracle Financials Cloud-connected Python applications and scripts for visualizing Oracle Financials Cloud data. This article shows how to use the pandas, SQLAlchemy, and Matplotlib built-in functions to connect to Oracle Financials Cloud data, execute queries, and visualize the results.

With built-in optimized data processing, the CData Python Connector offers unmatched performance for interacting with live Oracle Financials Cloud data in Python. When you issue complex SQL queries from Oracle Financials Cloud, the driver pushes supported SQL operations, like filters and aggregations, directly to Oracle Financials Cloud and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Connecting to Oracle Financials Cloud Data

Connecting to Oracle Financials Cloud data looks just like connecting to any relational data source. Create a connection string using the required connection properties. For this article, you will pass the connection string as a parameter to the create_engine function.

Using Basic Authentication

You must set the following to authenticate to Oracle ERP:

• Url: The Url of the account to connect to. Typically, the URL of your Oracle Cloud service. For example, https://servername.fa.us2.oraclecloud.com.
• User: The username of your account.
• Password: The password of your account.

Follow the procedure below to install the required modules and start accessing Oracle Financials Cloud through Python objects.

Install Required Modules

Use the pip utility to install the pandas & Matplotlib modules and the SQLAlchemy toolkit:

pip install pandas
pip install matplotlib
pip install sqlalchemy

Be sure to import the module with the following:

import pandas
import matplotlib.pyplot as plt
from sqlalchemy import create_engine

Visualize Oracle Financials Cloud Data in Python

You can now connect with a connection string. Use the create_engine function to create an Engine for working with Oracle Financials Cloud data.

engine = create_engine("oracleerp:///?Url=https://abc.oraclecloud.com&User=user&Password=password")

Execute SQL to Oracle Financials Cloud

Use the read_sql function from pandas to execute any SQL statement and store the resultset in a DataFrame.

df = pandas.read_sql("SELECT InvoiceId, Amount FROM Invoices WHERE Supplier = 'CData Software'", engine)

Visualize Oracle Financials Cloud Data

With the query results stored in a DataFrame, use the plot function to build a chart to display the Oracle Financials Cloud data. The show method displays the chart in a new window.

df.plot(kind="bar", x="InvoiceId", y="Amount")
plt.show()
