I have used this in open source projects as an embedded database and also for in-memory unit testing. It's a great contribution from IBM which enables even small, simple apps to easily integrate a database. It's also great for development as it matches the feature set of enterprise databases with a much smaller foot print. I wrote a tutorial on using Derby for isolated unit testing which was published on the IBM Developerworks site.    (Since: 2005)

I have used MSSQL Server (both 2000 and 2005 versions) for development of web applications and data quality tools. I have administrated server installations of the database and am familar with its performance optimizations. On my developer workstation I use the Express Edition which allows for isolated, compatability testing.    (Since: 2000)

I gained experience using v6.0 during the Landview Online project as FoxPro was the DB used for the ordering site I developed. My experience includes utilizing FoxPro from MS Active Server Pages (ASP).    (Since: 2000)

I have extensive knowledge of this excellent open-source database. This was our primary database for all of the web applications at Pason Systems, the largest of which had 200 GB of data. I spent a week in Houston in early 2002 taking a MySQL training course covering security, disaster prevention and recovery, replication, transactions, and system optimization. I also use this database for all of my personal software projects requiring a database. I am very impressed with this database as it definately becoming enterprise capable.     (Since: 1999)

Oracle is the primary database in use at Intervera and by our clients. As such, I have gained experience working with various versions (8, 9i, 10g) on large corporate servers and developer workstations. I use Oracle SQL Developer primarily during development but am comfortable with the sqlplus command-line tool. My development work has included learning the many optimizations in terms of schema definition and JDBC features that can result in significantly better read/write performance.    (Since: 1999)

I have some exposure with this advanced Open Source database on Linux. I plan on using this DB when I start evaluating EJB app servers on Linux.    (Since: 2000)
