Need an experienced professional who is experienced with ETL processes, data extraction and data merging. We have several (approx. 100) MySQL databases that required to be merged into a single database. Both the source and the target all have exactly same schemas (37 tables in the schema) and all are located on the same database server instance. Full schema documentation with sample data will be provided as part of the project kickoff. The ETL script must be provided such that a list of source and single target database can be specified in a configuration file. The ETL script can assume that all databases are located on the same server. I need a person to work on this ASAP. Please do not bid for this project unless you are able to start working on this within the next 5 days.

Hi, Let me introduce myself as an expert in Database design and analysis. I have worked on several database technologies like MS Access , SQL Server, Oracle,MySQL etc. I have more than 10 years of experience to my credit. I have worked data merging and consolidation in the past as well. I am assuming that it is plain merging and there are no data conflicts that need to be resolved as per some business rule. On this highly competitive site I fully understand how important it is to provide high quality work. My prime focus is 100% customer satisfaction. I would be happy to answer any queries that you may have. Looking forward to working with you. Thanks & Regards FineCoder

Hi, I am a MySQL database programmer and have worked with large databases. From what I am reading you need an ETL tool (script) which will merge data from different sources (having the same schema) into one central (or control) database. Some of the problems I can visualize is the presence of duplicate data - in what ways can they occur and if they do which database source would you keep and which will you reject. Please provide more details of the work so that I can review the schema and the associated PKs and FKs. If you can provide test data even better. Any questions, do let me know. Thanks Deb

I am having good exposure of ETL and databases. I have designed and maintained a complete ETL tool using UNIX shell script and Oracle (SQL, PL/SQL). We can have discussion if you are interested.

Depends on the RelationShips, If the tables have no relationships, the it would be as simple as creating the new table and insert all the rows in the tables
