The Demo Journey: From Raw Data to OMOP-Ready Insights
Step 1: Scanning Your Source Data with White Rabbit
The first act of our demo is all about data profiling. You’ll launch the White Rabbit application, and マカオのカジノ 中国人 it will prompt you to configure your source database connection. This is where you specify the database type, server address, port, username, and password.
Once connected, you simply select the tables you want to profile. White Rabbit then gets to work, meticulously examining each column within those tables. What does it look for?
Column Names & Data Types: パチンコ イベント Basic structural information.
Number of Rows & Unique Values: To understand cardinality.
Min/Max Values: Essential for numerical and date fields.
Top Frequencies: Identifying common values, which is super helpful for categorical data like gender or visit types.
Null Proportions: Highlighting potential data completeness issues.
This process can take some time, depending on the size and complexity of your dataset. But trust me, mj 麻雀 カジノ it’s worth the wait! The output is a comprehensive Scan Report, typically saved as an Excel file.
Let’s imagine a snippet of what such a scan report might look like for a hypothetical clinical dataset:
Table Name Column Name Data Type # Rows # Unique Values % Null Min Value Max Value Top 3 Frequencies (Value: Count)
Patients patient_id INT 150,000 150,000 0.00% 1 150,000 (1:1), (2:1), (3:1)
Patients gender VARCHAR 150,000 2 0.01% F M (M: 78,000), (F: 71,985), (NULL: 15)
Visits visit_date DATE 450,000 3,500 0.00% 2005-01-01 2023-12-31 (2022-05-10: 450), (2021-11-15: 420)
Conditions diag_code VARCHAR 200,000 8,000 0.00% I10 Z99. If you beloved this write-up and you would like to get extra details pertaining to パチンコ イベント kindly check out our own web site. 9 (J45.9: 1,200), (E11.9: 950)
This table, a direct output of White Rabbit, immediately gives you a transparent view of your data’s characteristics. You can spot potential issues (like that small percentage of null genders, or the high number of unique diagnosis codes) even before mapping begins!
Step 2: Mapping with Rabbit-in-a-Hat
Now for the truly interactive part of the demo: mapping! You’ll open Rabbit-in-a-Hat and カジノ dq11 宝箱 load the scan report generated by White Rabbit. The interface presents your source tables and commmon draw ベラジョンカジノ columns on one side, and the various OMOP CDM tables (like PERSON, VISIT_OCCURRENCE, CONDITION_OCCURRENCE, DRUG_EXPOSURE) on the other.
This is where your inner puzzle-solver comes out! You’ll drag your source columns to their corresponding OMOP CDM fields. For instance, you might drag your Patients.patient_id to PERSON.person_id, and Patients.gender to PERSON.gender_concept_id.
But Rabbit-in-a-Hat isn’t just a simple drag-and-drop tool. It’s smart!
Concept Suggestions: For many fields, especially those requiring specific OMOP concept IDs (like gender_concept_id or condition_concept_id), Rabbit-in-a-Hat will suggest relevant OMOP concept IDs based on the values in your source data’s top frequencies. For gender, it might suggest “Male (concept_id: 8507)” and “Female (concept_id: 8532)”, streamlining the process significantly.
Transformation Logic: You can define simple transformation logic directly within the tool, like concatenating fields or applying simple conditional statements.
This visual and guided approach is what makes White Rabbit so powerful. It demystifies the mapping process, making it accessible even if you’re not an OMOP expert. As one fictional, but undoubtedly happy, data scientist might say:
“Rabbit-in-a-Hat makes the daunting task of mapping data feel like a collaborative puzzle, guiding you towards the right OMOP concepts with surprising intuition. It’s truly a game-changer for anyone struggling with data standardization.”
Step 3: Generating DDL and ETL Scripts
Once you’ve completed your mapping within Rabbit-in-a-Hat, the final, glorious step of the demo is the generation of DDL (Data Definition Language) and ETL (Extract, Transform, Load) scripts. With a single click, Rabbit-in-a-Hat will produce:
DDL Script: SQL code to create the necessary OMOP CDM tables in your target database.
ETL Script: SQL code that will extract data from your source tables, transform it according to your mapping definitions, and load it into the newly created OMOP CDM tables.
These scripts are your golden ticket! You can then execute them on your database to automatically populate your OMOP CDM instance. This automation saves hundreds, if not thousands, of hours of manual coding and debugging.
