Hello: We currently have a data set consisting of about 10 million rows and about 30 columns. We expect the set to grow. The data is currently spread out over different Excel spreadsheet but we need a more manageable approach. We have a lot of calculations and need to be able to sort and filter the data. We need all this data to be stored in the same database. We're looking for an experienced database manager & a setup expert who can provide us with an actionable advise of the best options. We will provide you a data sample. We will require a written opinion to complete the project (this doesn't have to be long, just the essentials). Thank you.

HI, i am great at database management/importing . I suggest you to use PHP (laravel or custom made solution) to manage your tables, as database I prefer to selct PostgreSQL. But if your preferences are MySQL or any other i am fine with it. So question about future plan: will you continue to use excel files to add data or at future you will add data directly to db usign administration interface? And of course need to see calculations you perform.

Hi, With more than 5 years of extensive experience in database design and development, my experience ranging from startups to big organization like O2 ireland, jaguar land rover etc with distinction in SQL , SQL server and Mysql. I have done a similar sort of project for a start up having their data in flat files with billion rows of sales data. I design a database in MySQL ,transformed, append data using Talend (an ETL tool) and SQL to migrate and automate the flow of data in mysql database. I have given you high level summary of my past experience. Now for your scenario, my approach will be: 1)Design optimized database schema (If not exist) 2) Feed Excel data into talend (an open source ETL tool) 3) Make transformation and data sorting in Talend . 4) Load data in Mysql. 5)AUTOMATE flow for proper ingestion of data in mysql DB using talend. My second approach will be. 1)1)Design optimized database schema (If not exist) 2) Load excel data in SQL staging table, 3) Transform and sort the data using SQL. 4) Load data into target tables. 5) Automate process . I am new to freelance but I have a lot of experience in designing building such solution. If you like my approach , you can give me a test dataset and I can provide you with solution. Thanks

Hi, I've managed this kind of situation in the past. We can store all the data in a mysql db, but still we'll need a friendly front end to perform queries. It's better if we know in advance the queries to be made, in order to design the proper indexes to obtain the best performance from the storage engine. The front-end can be a webapp (python based) or an Access linked file. We can discuss it if you contact me through chat. Thanks for reading, best regards, Esteban
