Today's question is quirky - in PDFs, what does the "P" stand for? PDF started as a project code-named Camelot in 1991. The idea was that this simplified version of PostScript would be optimized for displaying pages on various screens and platforms. This means the PDF documents could be shared across disparate platforms without mutually compatible application software. The initial development was slow, little demand was seen, and due to early PDFs lacking web links capability, they lacked usefulness on the internet.
So what would the "P" stand for in this document format name?
Answer to yesterday's question: The term is "Data lake". Early data lakes supported pretty much batch-oriented processing only, interactions required expertise in Java and high level tools such as Apache Pig, Spark or Hive.
Use of the term "data lake" has been varying and can encompass various practices. Sometimes a "lake" is referred to being anything but a data warehouse. Ideally, the term should describe the concept of natural and raw data storage.
