While the original proposal would be to assist in SQL optimization and tuning at Company A1, the scope of such project would be very time-consuming and require specific expertise within the research team. The scope of the current project was therefore revised, and the new project would consist in determining the current standards and practices in the field of SQL and database optimization in a number of companies represented on the board. Conclusions would be based on a series of interviews with Database Administrators (DBA’s) from the different companies, and on current literature about the topic. The first meeting took place 6th February 2003, and interviews were held mainly throughout the spring Semester 2003. Results would be presented in a final paper, and a presentation would also be held at the end of the project. Individual summaries of the interviews conducted with the DBA’s are included in Part B. A representative set of questions used during the interviews is also included. -

Database Administration
Accolades for Database Administration “I’ve forgotten how many times I’ve recommended this book to people. It’s well written, to the point, and covers the topics that you need to know to become an effective DBA.” —Scott Ambler, Thought Leader, Agile Data Method “This is a well-written, well-organized guide to the practice of database administration. Unlike other books on general database theory or relational database theory, this book focuses more directly on the theory and reality of database administration as practiced by database professionals today, and does so without catering too much to any specific product implementation. As such, Database Administration is very well suited to anyone interested in surveying the job of a DBA or those in similar but more specific roles such as data modeler or database performance analyst.” —Sal Ricciardi, Program Manager, Microsoft “One of Craig’s hallmarks is his ability to write in a clear, easy-to-read fash- ion. The main purpose of any technical book is to transfer information from writer to reader, and Craig has done an excellent job. He wants the reader to learn—and it shows.” —Chris Foot, Manager, Remote DBA Experts and Oracle ACE “A complete and comprehensive listing of tasks and responsibilities for DBAs, ranging from creating the database environment to data warehouse administration, and everything in between.” —Mike Tarrani, Computer Consultant “I think every business manager and every IT manager should have a copy of this book.” —Dan Hotka, Independent Consultant and Oracle ACE “This book by Craig Mullins is wonderfully insightful and truly important. -

Introduction to Databases Presented by Yun Shen ([email protected]) Research Computing
Research Computing Introduction to Databases Presented by Yun Shen ([email protected]) Research Computing Introduction • What is Database • Key Concepts • Typical Applications and Demo • Lastest Trends Research Computing What is Database • Three levels to view: ▫ Level 1: literal meaning – the place where data is stored Database = Data + Base, the actual storage of all the information that are interested ▫ Level 2: Database Management System (DBMS) The software tool package that helps gatekeeper and manage data storage, access and maintenances. It can be either in personal usage scope (MS Access, SQLite) or enterprise level scope (Oracle, MySQL, MS SQL, etc). ▫ Level 3: Database Application All the possible applications built upon the data stored in databases (web site, BI application, ERP etc). Research Computing Examples at each level • Level 1: data collection text files in certain format: such as many bioinformatic databases the actual data files of databases that stored through certain DBMS, i.e. MySQL, SQL server, Oracle, Postgresql, etc. • Level 2: Database Management (DBMS) SQL Server, Oracle, MySQL, SQLite, MS Access, etc. • Level 3: Database Application Web/Mobile/Desktop standalone application - e-commerce, online banking, online registration, etc. Research Computing Examples at each level • Level 1: data collection text files in certain format: such as many bioinformatic databases the actual data files of databases that stored through certain DBMS, i.e. MySQL, SQL server, Oracle, Postgresql, etc. • Level 2: Database -
