Use Rapidminer Studio also like an ETL to create new database on a local server?

FMartin

Hello,

I would acquire rapidminer studio license first before investing in RM Server but I have got one question.
Are we able to prepare data with RM Studio and create/write new database on a local server (sqlserver) ?
New database available for RM Studio but also for any other software.
I suppose it does but I want to be sure.

Thanks

Hi@FMartin,

RapidMiner is capable of creating and maintaining databases. I've been using it for these purposes for many years.
I'm describing the operators for database access here for you.

You can use the operatorExecute SQLfor doing database-specific things like creating databases, users, schemas, tables etc.

Write Databaseappends data to an existing database table, overwrites existing data in the table if you want, and can even create the appropriate tables if they don't exist yet.

Update Databaseworks on an existing table. You define a combination of fields (one or more) that are unique in the table. If a matching record is already there, Update Database changes it (update). If not, it gets inserted.

Read Databasecan be used for reading entire tables/views, or executing complex SQL queries that return a result.

There's also theIn-Database Processing extensionthat can put complex data processing operations (join, filter, sort, transform) into the database by generating the SQL statements behind the scenes. You just work with RapidMiner operators and don't need to know SQL.

There's one limitation, though. RapidMiner works by loading all the data into the memory. If you work with very large tables, try to load them and then just filter and process the result instead of doing this in the database, you'll get a bad performance. This is where In-Database Processing helps.
