Typical challenges of building your data layer. Things we've learnt from dozens of growing companies
Read more...When you start a digital product you usually put your data in a database. It does not matter if it is a simple text file, an excel spreadsheet or a managed Postgres instance on the cloud, your data always lives somewhere. Data has been a key component of any digital product for a long time now, but it hasn’t been until recently that we’ve started to devote significant resources to aggregating and making use of it. Even if you think you are devoting enough energy to data within your organization, most probably you aren’t.
