Data Analysis Using SQL and Excel
The description of data processing is organized around the SQL language.
Databases such as Oracle, Postgres, MySQL, IBM DB2, and Microsoft SQL Server
are common in the business world, storing the vast majority of business data
transactions. The good news is that all relational databases support SQL as a
query language. However, just as England and the United States have been
described as “two countries separated by a common language,” each database
supports a slightly different dialect of SQL. The Appendix contains a list of how
commonly used functionality is represented in various different dialects.
Similarly, beautiful presentation tools and professional graphics packages are
available. However, rare and exceptional is the workplace computer that does not
have Excel or an equivalent spreadsheet.
