As to what the actual difference is between those two options - well that could go on to be a very long answer but essentially LVM deals with extents and has multiple additional layers of abstraction that clearly need to be considered during boot - whereas the standard Linux PT should be a lot more starightforward than ...

Both the SQLite and MYSQL have certain advantages. SQLite is file-based — the database consists of a single file on the disk, which makes it extremely portable and reliable. Although it might appear like a “simple” DB implementation, SQL is used in SQLite. ... On the other hand, MySQL is very easy to work with.

MyISAM is designed with the idea that your database is queried far more than its updated and as a result it performs very fast read operations. If your read to write(insert|update) ratio is less than 15% its better to use MyISAM.

The answer is that PL/SQL is not growing, but not going away either. Because it is used in the Oracle database, and the Oracle database is a fixture of enterprise systems world-wide, it will outlive you.

In other cases, the best and most cost-effective way to maintain system reliability and performance is to split off resources to run your database from a separate server. ... The roles and requirements of database and web or application servers are quite different, and separating them can provide a number of benefits.

The key to the fast performance offered by Exadata is the offloading of database processing from the database server to a highly optimized storage server. Oracle uses a feature called the Exadata Smart Flash cache to speed up the database processing by making I/O operations much faster.

Compare this to a typical Oracle data block at around 8 Kilobytes. Whereas Oracle will manage a range of OLTP and OLAP, processing lots of short running transactions with single row lookups, Hadoop is more suited to single process batch operations.

Amazon RDS is easier to set up, manage, and maintain than running Oracle Database in Amazon EC2, and lets you focus on other tasks rather than the day-to-day administration of Oracle Database. Alternatively, running Oracle Database in Amazon EC2 gives you more control, flexibility, and choice.
