Over deze dienst
Welcome to the ultimate solution for your database migration needs!
Are you struggling to move critical business data from messy Excel spreadsheets into a robust Oracle Database? Manual data entry is slow, risky, and prone to errors. Let a professional handle it.
I am an experienced Database Engineer and ETL Developer. I specialize in building secure, efficient, and accurate data migration pipelines. Whether you need a simple one-time import or a complex legacy database upgrade, I will ensure your data lands perfectly in your Oracle system with zero data loss.
Services Offered in This Gig:
- Data Migration: Flawless import from Excel (.xlsx, .xls, .csv) to Oracle DB.
- Schema Design & Mapping: Creating staging tables, primary keys, and foreign keys.
- Data Cleaning & Scrubbing: Fixing formatting, handling null values, and removing duplicates.
- Data Transformation: Data type casting (converting text to Date/Number formats).
- Stored Procedures & PL/SQL Scripts: Custom code for automated data loading and validation.
IMPORTANT:
Database migration complexity depends entirely on your data structure, cleaning needs, and schema requirements. Please message me these 3 information before ordering.
Veelgestelde vragen
What information do you need from me to start the migration?
I need your source Excel/CSV files, your target Oracle database schema details (table structures or DDL scripts), and clear instructions on how the columns should match up (data mapping rules).
Do you provide a report or verification after the migration?
Yes. Every delivery includes a comprehensive migration report and data validation checks. I compare row counts and check for data truncation to prove that 100% of your records migrated successfully.
Will the migration cause any downtime for my live database?
No. I typically write and test the migration scripts in a staging or test environment first. Once everything is verified perfectly, the final import can be scheduled during your off-peak hours to avoid disruptions.
What tools do you use for Oracle data migration?
Depending on your database version and file size, I use industry-standard tools including Oracle SQL*Loader, External Tables, Oracle SQL Developer, custom PL/SQL scripts, or Python scripts.
Can you handle messy Excel data that needs a lot of cleaning?
Yes! I can clean up formatting errors, remove duplicate entries, fix broken dates, and handle missing (null) values. Please note that extensive data cleaning falls under my Standard or Premium packages.
Is my data safe and confidential with you?
Absolutely. Data security is my highest priority. I treat all client data with strict confidentiality. If required, I am happy to sign a Non-Disclosure Agreement (NDA) before you share any files.
