.FREE PDF ⚇ SQL Antipatterns ♍ eBooks or Kindle ePUB free
I m a software developer who gets paid mostly for working on the back end portion of solutions and I ve worked in both small and large companies I am not an SQL guru and I am than happy to let somebody else review and fine tune any SQL that the solution uses If I m lucky, I ll be working in an organization large enough to have full time SQL experts who can help me out More times than not, however, the development team has to craft the SQL ourselves As of late, I ve been letting Hibernate do most of the heavy lifting for me, trusting that it will generate reasonable SQL and keep me out of hot water I fully understand that, like most tools, Hibernate is only as useful as the developer s understanding of it which is why I try and read up on the ins and outs of Hibernate as much as I can To that end, I figured I d pick up a copy of SQL Antipatterns Avoiding the Pitfalls of Database Programming to help me understand if I was asking Hibernate to do something silly and I m really glad that I did Some of the anti patterns I ve seen before, like not using using constraints or using a column to mean multiple things, but there are many I haven t seen before but should now be able to spot I enjoyed the discussions around security and can appreciate that storing passwords in the database is a bad idea I ve seen that than once and have a better understanding on how to protect against SQL injection attacks The section on application development was a pleasant surprise to me because it talks about testing and possible migration strategies I also enjoyed the comparison of the Active Record pattern versus the Repository pattern as it convinced me that the decision to use Repository on my current project was a reasonable one All in all, I loved the book and recommend that anybody who has to deal with a relational store pick up a copy and give it a read It isn t a very long book but you get the sense that the advice given came from some hard learned lessons on the job. I thought this book was ok All the anti patterns are good to be aware of, but I d say they vary in likelihood Some are mistakes I would expect only a real newbie to make Others, like SQL injection, are useful sections that try to dispel myths believed by experienced users even now.My edition was published in 2010, so I shouldn t be surprised that the non SQL code examples such as for dynamic SQL are in PHP I also can t fault the book s age for having such a small section on relational mappers.All in all, a decent read for a new SQL user, but if you have any experience with SQL you might want to skip this one for a newer reference. First, this is based on B6.0 printing, version 2010 4 1.I was hoping to get a little out of this book I bought it because I saw the excerpt from the chapter Naive Trees and the statement most developers aren t SQL experts, and most of the SQL that gets used is inefficient, hard to maintain, and sometimes just plain wrong, on PragProg Bookshelf Not wanting to create poor SQL, I knew I needed this book.I struggled for a long time with a database that had a large tree structure, so I m always looking for better ways of dealing with trees in databases After a lot of work, I finally ended up with what basically equates to the Enumerated Path pattern I wish I d had this book a few years ago when I started that project it would have saved me a ton of time.I think the chapters are well written, and seem to cover a lot of issues a developer might encounter in his first few years of development The author uses good, real world, examples written in clear language.If you re a developer struggling with database problems, I d say, pick this book up If you ve been developing for upwards of 10 years, you can probably skip it, hopefully, you ll already know most everything he covers. This is a catalog of what the author considers widespread bad practices in the use of relational databases and SQL programming.Most antipatterns are about misunderstandings on good database design for example, the author discusses such timeless classics as implementing many to many relationships by putting multiple comma separated values in a row For instance, the database backing a blog whose posts can have an arbitrary number of tags would have a column TAGS with entries such as tag1, tag2, tag4.I would have appreciated some concrete discussions on writing performant SQL queries I am no SQL expert but am wary of writing complicated JOIN statements, but this fear is a mostly irrational one I would have liked to see this important topic addressed.It s a nice compendium of practices to avoid with highly memorable titles Pseudokey neat freak is my favorite , but I m not sure this would be the first title one should read on the subject. This book was recommended by some programmer friends of mine, and proved to be a good read It is not about TSQL thought The book is mainly about some basic ideas that people should have in mind when designing database models It s a fast read. It s a pretty good book on SQL It is aimed at people with beginner medium SQL experience Beginners will not really understand what s happening there And if you ve written the database interface layer for 3 5 apps, it might be partially interesting for you.If you re advanced with SQL, you already know these patterns. .FREE PDF ⚒ SQL Antipatterns ♌ Bill Karwin Has Helped Thousands Of People Write Better SQL And Build Stronger Relational Databases Now He S Sharing His Collection Of Antipatterns The Most Common Errors He S Identified In Those Thousands Of Requests For HelpMost Developers Aren T SQL Experts, And Most Of The SQL That Gets Used Is Inefficient, Hard To Maintain, And Sometimes Just Plain Wrong This Book Shows You All The Common Mistakes, And Then Leads You Through The Best Fixes What S , It Shows You What S Behind These Fixes, So You Ll Learn A Lot About Relational Databases Along The WayEach Chapter In This Book Helps You Identify, Explain, And Correct A Unique And Dangerous Antipattern The Four Parts Of The Book Group The Anti Patterns In Terms Of Logical Database Design, Physical Database Design, Queries, And Application Development The Chances Are Good That Your Application S Database Layer Already Contains Problems Such As Index Shotgun, Keyless Entry, Fear Of The Unknown, And Spaghetti Query This Book Will Help You And Your Team Find Them Even Better, It Will Also Show You How To Fix Them, And How To Avoid These And Other Problems In The FutureSQL Antipatterns Gives You A Rare Glimpse Into An SQL Expert S Playbook Now You Can Stamp Out These Common Database Errors Once And For AllWhatever Platform Or Programming Language You Use, Whether You Re A Junior Programmer Or A PhD SQL Antipatterns Will Show You How To Design And Build Databases, How To Write Better Database Queries, And How To Integrate SQL Programming With Your Application Like An Expert You Ll Also Learn The Best And Most Current Technology For Full Text Search, How To Design Code That Is Resistant To SQL Injection Attacks, And Other Techniques For Success It s a very good book for the people, who just learned SQL I regret that I did not read it before, because it will resolve some of issues during my work. As someone struggling to design my website s database, this book hit the spot I couldn t have imagined all the things I had wrong I m so glad I found this gem. With many relational database systems available in the market, I find there is not much need to design a RDBMS product to the level this book gives Working with data analytics, I found part 3 to be the most useful with Query Antipatterns Majority of the issues are addressed with proper training so I can see this book would be good for those who are self learners who may not have many opportunities for formal training The book is written in a format that gives the antipattern as an example, then provides the best solution Decent book overall, but I didn t get much out of the content or saw examples that shouldn t happen unless proper practices weren t followed.
