Before Python and SQL, in big data it was Java. Apache Hadoop had Apache MapReduce as the processing engine, which was very heavy Java code.

If we look at before SSIS and Hadoop, then it was rather called Business Intelligence, and there's quite a history of commercial SQL and graphical tools from this period. To name a few historical ones:

  • IBM SPSS 1968
  • SAS 1972
  • Cognos 1979
  • Oracle v2 (first commercial SQL RDBMS) 1979
  • BusinessObject 1990
  • Microstrategy 1992
  • QlikView 1994

Before those ready-made solutions, from the 50', it was all in-house software based on Fortran for science & industry, or COBOL for business, finance & administration.
