About the AuthorsSalahaldin Juba has over than a decade of experience in the industry and academia, with afocus on database development for large-scale and enterprise applications. He holds amaster's degree of science in environmental management with a distinction, and abachelor's degree of engineering in computer systems. He is also a Microsoft CertifiedSolution Developer (MCSD).He has worked mainly with SQL server, PostgreSQL, and Greenplum databases. He hasdeveloped applications for scientific communities to process GIS information in adistributed manner, and he has participated in many international projects and standardsfor image processing during his work in the academic sector.As a software engineer, he works mainly with defining ETL processes with external parties,defining software solution, promoting SQL best practices, designing OLTP and OLAPapplication, scouting and evaluating new technologies, and providing training andconsultation services.I would like to express my deepest gratitude to my colleague Andrey Volkov for makingthis work possible. Also, I would like to thank all the people who provided support,especially the team at Packt for their great support and feedback with proofreading, design,comments, and remarks. I would also like to thank my family for their support despite all ofthe time that I had to devote to this book over them. Finally, very warm and deep thanks tomy late father, Ikrayem Juba, for his utmost support, help, and guidance.

Andrey Volkov has studied information systems in banking. He started his career as afinancial analyst in a commercial bank. Using databases as a main tool in his work, herealized that querying the database directly and mastering SQL is much more efficient forad hoc analysis than using any visual reporting software. He joined the data warehouseteam, and after some time, he lead the team by taking the position of the data warehousearchitect.He has worked mainly with Oracle and used to develop logical and physical models offinancial and accounting data, implement them in the database, develop ETL processes, andperform analytical tasks. He was also responsible for teaching the users how to use the datawarehouse and BI tools. SQL training was also a part of that work.After 10 years in the financial sector, he changed his field and now works as a seniordatabase developer in a telecommunications company. Here, he works mainly withPostgreSQL databases, being responsible for data modeling and implementing physicaldata structures, developing stored procedures, integrating databases with other softwarecomponents, and developing a data warehouse.Having a lot of experience with both Oracle and PostgreSQL--the leading commercial andone of the most advanced open source RDBMSes--he is able to compare them and recognizeand evaluate the key advantages of both of them. Working as a software developer andimplementing different kinds of database applications, as well as working as a businessanalyst and using databases as a tool for analysis, let him learn and understand differentdatabase features in different use cases. This experience made him able and willing to workon this book.I would like to thank my wife and son for their support and for letting me work onweekends and evenings. Big thanks to the editors team for their support, guidance, andorganization. And most of all, I would like to thank the main author of the book, SalahaldinJuba, who invited me to work on the book, introduced me to the team, and, in fact, has donemost of the work.
