Beginning SQL Queries, 2nd Edition is a friendly and easily read guide to writing queries with the all-important - in the database world - SQL language. Anyone who does any work at all with databases needs to know something of SQL, and that increasingly today includes those using so-called NoSQL databases, because a strong trend in the industry is to make those databases accessible from SQL after all, at least for reporting purposes, and for analysis. Beginning SQL Queries, 2nd Edition is written by the author of Beginning Database Design, an author who is garnering great reviews on Amazon due to the clarity and succinctness of her writing.
