Introduction to Logical Storage Structures. Oracle Database allocates logical space for all data in the database. At a physical level, the data is stored in data files on disk (see Chapter 11, "Physical Storage Structures"). The data in the data files is stored in operating system blocks.
.
Considering this, in which format data is stored in Oracle database?
Most Oracle databases store files in a file system, which is a data structure built inside a contiguous disk address space. All operating systems have file managers that allocate and deallocate disk space into files within a file system. A file system enables disk space to be allocated to many files.
