Tibero stores data files on one or more non-volatile storages. However, in 2008 TmaxSoft released its own in-memory DBMS called Tibero MMDB. In 2012, the company has made an interview that it is currently considering amalgamating the original disk-oriented product with its in-memory DBMS in the future.
Virtual Views Materialized Views
Tibero supports virtual views. It uses materialized views to optimize queries.
N-ary Storage Model (Row/Record)
Tibero stores table rows in a disk block until the block's free space reaches a percentage below a configurable parameter. Large objects are stored in multiple blocks unless the parameter is configured to be sufficiently large.
Tibero uses B-Trees to create indexes. It also supports organizing tables with clustered indexes on primary keys. Searching on indexes can be done with single attributes or on a range. An index can be created and searched on composite key from multiple attributes. BitMap Indexing is supported for OLAP data warehouses.
At a physical level, Tibero stores a control file that acts as a directory to keep track of all data files in the database. The data files each belong to a tablespace which refers to a specific table/index. At a logical level, data files are organized as a collection of blocks within a tablespace.
