Oracle SQL

Oracle Database is a relational database management systemandreleased by Oracle Corporation. Oracle Database has become a major feature of database computing.

An Oracle database system comprises at least one instance of the application, along with data storage. An instance comprises a set of operating-system processes and memory-structures that interact with the storage. Typical processes include PMON (the process monitor) and SMON (the system monitor).

Users of Oracle databases refer to the server-side memory-structure as the SGA (System Global Area). The SGA typically holds cache information such as data-buffers, SQL commands and user information. In addition to storage, the database consists of online redo logs (which hold transactional history). Processes can in turn archive the online redo logs into archive logs (offline redo logs), which provide the basis (if necessary) for data recovery and for some forms of data replication.

The Oracle RDBMS stores data logically in the form of tablespaces and physically in the form of data files. Tablespaces can contain various types of memory segments; for example, Data Segments, Index Segments etc. Segments in turn comprise one or more extents. Extents comprise groups of contiguous data blocks. Data blocks form the basic units of data storage. At the physical level, data-files comprise one or more data blocks, where the block size can vary between data-files.

Oracle databases can be used to create distributed database running over contiguous or disparate logistical locations. It can be used to store data and information and provides high availably and performance and is used extensively as a practial and reliable database.

We can design and engineer databases based on your business model and provide tools and interfaces that can be used to mine your business data. We also have experience in database persistence and create custom persistence frameworks and algorythms which can be used to predict patterns and trends from your data.
