Your dataset becomes too big for Excel to handle.In our example use case, we would run into this issue. If you need to connect your customers and orders table, you end up having to learn functions like XLOOKUP and VLOOKUP, which are neither intuitive nor convenient. Your dataset does not fit into a single table.Storage is within the Excel file itself.The ETL process mainly involves you opening a CSV or XLSX file.If you have a CSV export from an existing system that already contains somewhat aggregated data, then Excel is a good place to start. It’s ideal if your dataset for analysis fits into a single table and the file size is measured in up to tens of megabytes. It’s a perfectly capable analytics tool if you know how to create pivot tables and graphs. Tier 1: Microsoft Excel (or Google Sheets)Įxcel excels at many things. We want to analyse the data, create visualisations and share them with our co-workers. Analytics: the tool we use for the analytics.Extract, Transform, Load process (ETL): getting the data from the source to the desired destination.In typical data analytics use cases we need to build the following pipeline: You would turn to analytics solutions if a standard report from your sales or ERP did not give you enough information to conduct the analysis. An example would be: ‘In what circumstances do men buy more sneakers than women?’. In this article, we’re aiming for use cases that solve relatively simple issues. But there are also a lot of relatively simple problems.
For some of them, you may need a data warehouse or machine learning or ‘big data’.
There are many complex problems that can be solved with data analytics. Here are the best data analytics tools that you can use for free.įree doesn’t always mean simple, as I’ll show, but it’s a good philosophy to be guided by at first.
