Building a Relationship Map Using Oracle APEX no-code platform and Oracle Database 23 ai

 



I am active on social media platforms like X, LinkedIn, and Threads. I like understanding how influencer relationships can provide valuable insights into my networks and trends. With Oracle APEX and the power of Oracle Database 23ai, I have created a robust influencer map to visualize these relationships. This blog post will guide you through building a similar relationship map using Oracle APEX and open-source data or your own dataset. I will go over the brief steps and then follow up with the detailed ones.

Step 1: Set Up Your Oracle APEX Environment

Before creating the relationship map, ensure you have a working Oracle APEX environment.

Create an Oracle APEX Workspace:

Step 2: Load Open-Source Data

For this example, we will use a Twitter dataset available on Kaggle.

Download the Dataset:

Go to Kaggle’s Twitter Data and download the dataset.

Create Tables to Store Data:

In Oracle APEX, navigate to SQL Workshop > SQL Commands and create tables for storing influencer and relationship data.

CREATE TABLE influencers (
id NUMBER PRIMARY KEY,
name VARCHAR2(100),
followers NUMBER,
following NUMBER,
tweets NUMBER
);

CREATE TABLE relationships (
id NUMBER PRIMARY KEY,
source NUMBER REFERENCES influencers(id),
destination NUMBER REFERENCES influencers(id)
);

Load Data into Tables:

Go to SQL Workshop > Utilities > Data Workshop and import your CSV files into the influencers and relationships tables.

Step 3: Create an APEX Application

Create a New Application:

Go to App Builder > Create > New Application.

Name your application (e.g., “Influencer Map”).

Add Pages to the Application:

Add a Dashboard page to display key metrics.

Add an Interactive Report page for the influencers table.

Add an Interactive Report page for the relationships table.

Add a Graph Visualization page to visualize the influencer network.

Step 4: Configure the Network Diagram

Let’s set up the Oracle JET Network Diagram to visualize the relationships.

Create a New Page for the Network Diagram:

Go to App Builder and add a new “Chart” > “Other” > “Network Diagram” page.

Name the page (e.g., “Influencer Network”) and finish the setup.

Configure the Data Sources for the Network Diagram:

Open the Network Diagram page.

Nodes Section:

Source Type: SQL Query
SQL Query:
SELECT
'n' || id AS id,
name AS label,
followers AS size,
NULL AS group_id
FROM influencers;

ID Column: id
Label Column: label
Size Column: size
Group Column: group_id

Links Section:

Source Type: SQL Query
SQL Query:
SELECT
'n' || source AS source,
'n' || destination AS destination,
NULL AS link_id
FROM relationships;

Source Column: source
Destination Column: destination
Link ID Column: link_id

Customize Node and Link Properties:

Node Styling:

Size: Based on followers count (size column)
Tooltip: Name: {label}, Followers: {size}

Link Styling:

Source Type: SQL Query
SQL Query:
SELECT
'n' || source AS source,
'n' || destination AS destination,
NULL AS link_id
FROM relationships;

Source Column: source
Destination Column: destination
Link ID Column: link_id

Customize Node and Link Properties:

Node Styling:

Size: Based on followers count (size column)
Tooltip: Name: {label}, Followers: {size}

Link Styling:

Uniform styling
Tooltip: Source: {source}, Destination: {destination}

Step 5: Deploy and Test Your Application

Save Your Changes:

Click on “Save” to apply all the configurations.

Run the Application:

Click on the “Run” button to deploy your application.

Test the network diagram to ensure that nodes and links are displayed correctly.

Following these steps, you’ve successfully created an influencer map using Oracle APEX and open-source Twitter data. This powerful visualization can help you understand the relationships and dynamics within social networks.

Oracle APEX’s integration with Oracle JET provides a robust platform for creating interactive and insightful visualizations, making it an excellent choice for analyzing complex data relationships.

— Download the dataset and prepare it for import (usually CSV format).

Create Tables to Store Data:
— In Oracle APEX, go to SQL Workshop > SQL Commands and create tables to store the data.

CREATE TABLE influencers (
    id NUMBER PRIMARY KEY,
    name VARCHAR2(100),
    followers NUMBER,
    following NUMBER,
    tweets NUMBER
);

CREATE TABLE relationships (
    id NUMBER PRIMARY KEY,
    source NUMBER REFERENCES influencers(id),
    destination NUMBER REFERENCES influencers(id)
);
Load Data into Tables:
— Go to SQL Workshop > Utilities > Data Workshop and import your CSV files into the `influencers` and `relationships` tables.
STEP3
Create an APEX Application
Create a New Application:
— Go to App Builder > Create > New Application.
— Name your application (e.g., “Influencer Map”).
Add Pages to the Application:
— Add a Dashboard page to display key metrics.
— Add an Interactive Report page for the `influencers` table.
— Add an Interactive Report page for the `relationships` table.
— Add a Graph Visualization page to visualize the influencer network.
STEP4

Official Disclaimer : The views and opinions expressed in this blog are those of the author and do not necessarily reflect the official policy or position of Oracle Corporation. This post was developed jointly with Mohamad Charaf, Oracle Enterprise Cloud Architect. If you have two tenancies in the same region, and you want to copy data that is stored in Object Storage from one tenancy to the other without making the buckets public, this action requires some additional types of identity and access management (IAM) policies. This blog post walks you through how to create these policies. For this example, the source tenancy is named ACMEBMCS and the destination tenancy is named ACMEOCISA. In ACMEBMCS, the Object Storage buckets are in the benchmark compartment. In ACMEOCISA, the target compartment is oracleexa . The follow

  I am an Atheist. Born in a Hindu family, I have experimented with Christianity and Buddhism. Jokingly, I describe my journey from Many Gods to One and then None. I followed Hinayana Buddhism for a long time. Lately, I have been studying Lokayata/Carvaka school of the Hindu Darsana (philosophy). I like to be identified as a Hindu Atheist. Why Hindu? Because my birthplace is on the east side of the River Indus.

Indian Freedom Fighters — Were they someone’s terrorists?

  In the wake of the heinous event of October 7th and the aftermath that followed, we are continually horrified by the news emerging from Israel and Gaza. Imagine how terrible it is for the people who are the news, living in that hellish condition on either side of the conflict. We, Bengalis, have a long tradition of meeting over the weekends — adda — and spending time having tea and trying to solve world problems. These often lead to severe argumentation. I guess fellow Bengali esteemed Prof. Amartya Sen, Noble Laurate, also pointed to this tradition in his book The Argumentative Indian (ISBN: 978–0312426026). So the topic came up whether the Indian Revolutionaries fighting against the British Raj were haloed freedom fighters or despicable terrorists. I am no historian, so with limited knowledge and coming from a family of “Indian Freedom Fighters,” I will attempt to rationalize why within a scope, the Indian revolutionaries were not terrorists by today’s definition.
