As an Oracle Cloud HCM customer and practitioner, I frequently rely on the Oracle Cloud Applications Documentation to understand how various tables and views are structured. Whether I’m building BI Publisher queries, supporting Fast Formulas, or troubleshooting integrations, knowing the exact column names and their meanings is essential.
But manually digging through dozens (or hundreds) of HTML pages is time-consuming and repetitive.
So, I decided to automate it in a way that would allow me to have conversations with this data versus clicking through hundreds of pages aimlessly looking for answers.
What I Built
I created a Python-based command-line tool that extracts Oracle's publicly available HCM documentation, regarding tables and views, and outputs structured metadata for tables and views into clean JSON files. This helps streamline research, improve automation, and accelerate troubleshooting for internal support.
Here’s what it does:
-
Parses the
toc.jsfile from Oracle’s documentation site to extract all table/view URLs -
Visits each documentation page using a headless browser
-
Extracts metadata such as:
-
For Tables: table name, description, details, columns (with data types), primary keys, and indexes
-
For Views: view name, description, details, column names, and SQL query
-
No more flipping through documentation pages—just clean, structured data ready for analysis or integration into support tools, with many useful use cases including those in the AI landscape.
How It Works
Step 1: Extract Links from toc.js
The Oracle documentation includes a toc.js file which holds all the links to individual table and view pages. The tool first parses that file to build a list of URLs.
python oracle_hcm_cli_tool.py --toc toc.js --csv oracle_links.csv
Step 2: Convert CSV to JSON
For downstream processing, the CSV is converted to a simple JSON array of {name, url} pairs.
python oracle_hcm_cli_tool.py --csv oracle_links.csv --json oracle_links.json
Step 3: Extract Table and View Metadata
The final step launches a headless browser with Playwright and visits each page to extract structured metadata.
python oracle_hcm_cli_tool.py --json oracle_links.json --tables oracle_tables.json --views oracle_views.json
Or all three steps in one:
python oracle_hcm_cli_tool.py --toc toc.js --csv oracle_links.csv --json oracle_links.json --tables tables.json --views views.json
Output Format
Here’s what the output looks like.
For Tables (tables.json)
{
"table_name": "PER_ALL_PEOPLE_F",
"url": "...",
"description": "This table stores information about...",
"details": "Schema: FUSION Object owner: PER Object type: TABLE Tablespace: APPS_TS_TX_DATA",
"columns": [
{
"column_name": "PERSON_ID",
"data_type": "NUMBER",
"length": "",
"precision": "18",
"not_null": true,
"description": "System generated surrogate key"
},
...
],
"primary_key": {
"name": "PER_PEOPLE_F_PK",
"columns": ["PERSON_ID", "EFFECTIVE_START_DATE", "EFFECTIVE_END_DATE"]
},
"indexes": [
{
"name": "PER_PEOPLE_F_U1",
"uniqueness": "Unique",
"columns": ["BUSINESS_GROUP_ID", "PERSON_NUMBER"]
}
]
}
For Views (views.json)
{
"view_name": "FAI_DEEP_LINKS_VL",
"url": "...",
"description": "This view shows deep link metadata...",
"details": "Schema: FUSION Object owner: FAI Object type: VIEW",
"columns": [
{ "column_name": "DEEP_LINK_ID" },
{ "column_name": "DEEP_LINK_CODE" },
...
],
"sql_query": "SELECT ... FROM FAI_DEEP_LINKS_B b ..."
}
Why This Is Useful
This tool is a game-changer if you:
-
Frequently need to understand Oracle's schema to troubleshoot or write custom reports
-
Work in integrations, BI, or payroll support and need faster insights
-
Want to build dashboards or internal tools that visualize schema metadata
-
Need a starting point for building generative AI agents or search interfaces that utilize documentation in order to drive intelligent insights
This same approach can be followed for Oracle ERP, and other use cases, for Oracle customers
