MySQL Database Consolidation
Budget: ₹1,500 – ₹12,500 INR
Database Merging Requirement
Project Title: Merging 9 MySQL Databases into a Single Consolidated Database
Project Overview:
We have 8 MySQL 5.6.17 databases that share the same schema (same tables and columns) but contain different data. The primary keys (IDs) start from 1 in each database, which will cause conflicts when merging.
The goal is to merge all 8 databases into a single database (merged_db) while ensuring:
No data is lost
All primary keys are unique
Foreign key relationships remain intact
Performance is optimized for future scalability
Scope of Work:
Database Analysis:
Structure of tables and columns is identical across all databases.
Primary keys (ID) start from 1 in each database, requiring modification.
Foreign key relationships need to be maintained.
New Consolidated Database (merged_db) Creation:
Create a new database (merged_db) with the same schema.
Ensure all necessary indexes and constraints are included.
Data Migration & Handling Primary Key Conflicts:
Since all databases have overlapping IDs, use an ID offset strategy:
Assign a unique range to each database.
Example:
db1: IDs 1 - 100000
db2: IDs 100001 - 200000
db3: IDs 200001 - 300000
And so on...
Update foreign key references to reflect new IDs.
Insert data into merged_db while shifting IDs dynamically.
Automation of Data Transfer:
Write a script (PHP/Python) to:
Read data from each source database.
Modify primary key values dynamically.
Insert data into merged_db.
Testing & Validation:
Verify that all records from all 8 databases are successfully migrated.
Ensure foreign key relationships remain valid.
Check for performance bottlenecks and optimize indexes if needed.
Backup & Deployment:
Backup all 8 source databases before merging.
Provide a final dump of merged_db after successful completion.
Technical Requirements:
MySQL Version
5.6.17
Number of Databases
8
Database Schema
Identical across all 8 DBs
Primary Key Handling
Offset-based ID shifting
Foreign Keys
Must be preserved
Automation
Scripted solution in PHP or Python
Deliverables:
New consolidated database (merged_db)
Script to automate data merging
Final SQL dump of merged_db
Documentation of the merging process
