Getting value from IoT, Integration and Data Analytics
In our daily work we are dealing with data from many sources. Data in CSV files, from Cloud APIs, in mail servers, configuration files, Terraform plans, in logging systems, source code repositories and many more. Different formats, access methods, tools. And retrieving data from one such source can be challenging […]
