This is of course a quite diminutive ETL job. When you issue complex SQL queries from REST, the driver. With built-in, optimized data processing, the CData Python Connector offers unmatched performance for interacting with live REST data in Python. You transformed the data using the Power Query editor This article shows how to connect to REST with the CData Python Connector and use petl and pandas to extract, transform, and load REST data.You extracted the raw data from an Excel table.You will see the “transformed extract” of your housing data loaded into Excel:Ĭongratulations for completing an entire ETL job! Loadįinally, click Home on the Power Query editor, then Close & Load. But let’s move to that last leg, or L for load (say that 10 times fast!) 3. There’s of course a lot more you can do with data transformation in Power Query, and most of your time is going to be in this step of ETL. To do this, go to Transform on the Power Query ribbon, then Index Column > From 1: Let’s make a very simple transformation to this data: we will add an index column. Adding, dropping, renaming or calculating columns.With built-in, optimized data processing, the CData Python Connector offers unmatched performance for interacting with live SAP data in Python. With built-in, optimized data processing, the CData Python Connector offers unmatched performance for interacting with live MySQL data in Python. This could be a whole lot of things, but it’s really all the steps you must take to make this data usable, such as: This article shows how to connect to SAP with the CData Python Connector and use petl and pandas to extract, transform, and load SAP data. This article shows how to connect to MySQL with the CData Python Connector and use petl and pandas to extract, transform, and load MySQL data. To do so, click anywhere inside the housing table, then go to Data > Get Data > From Table/Range:Ĭongratulations on getting the ETL started! An E for effort… and extract! Let’s move to the T. So let’s connect to this data, then transform it (There’s the T!). We must take an extract of it (There’s the E). What makes this such a powerful idea is that Power Query is forcing us to keep the raw data intact. Now it seems a little strange to be “connecting to and extracting” data that we already have, right in this workbook. ETL, which stands for extract, transform, and load, is the process data engineers use to extract data from different sources, transform the data into a usable and trusted resource, and load that data into the systems end-users can access and use downstream to solve business problems. Our first order of business is to extract the data from the housing table. ETL (extract, transform, load) tools are required to ensure data is integrated between external sources and Microsoft SQL Server.
