Data Lake
A Data Lake is like a giant digital storage space where organizations keep all types of information in its original form. Think of it as a vast reservoir where government agencies store everything from citizen records to public service data, before it gets organized or processed. Unlike traditional storage systems that only accept specific types of data, a Data Lake can hold any kind of information - from simple text documents to complex video files. This makes it easier for government workers to access and analyze information when needed, especially for big projects or public service improvements. Similar concepts include Data Warehouse or Information Repository, but Data Lakes are more flexible in what they can store.
