McObject releases ExtremeDB 4.1 with enhancements in the areas of security, performance and reliability.
McObject has updated its flagship embedded database with a host of new
features intended to improve performance, reliability and security.
In ExtremeDB 4.1, McObject has added hooks to "enable developers to
provide a desired character-sorting sequence (collation) for data stored as
text, including collation that supports a particular language or combination of
languages," the company said in a May 11 news release. In addition, the
latest version can "save a database as a binary image and then restore it
with a changed schema, or layout of tables, fields, indexes and other elements,"
allowing customers to accomplish
changes more quickly.
"Our support for custom collations enables you to build into your
application any of the collation approaches typically supported by large
enterprise databases or even a customized collation that is unique to your
application," McObject Marketing Director Ted Kenney told eWEEK in an
McObject also strengthened "the Disk Manager process that manages
interaction with persistent media ... in ExtremeDB Fusion, McObject's hybrid
in-memory/on-disk embedded database. Improvements include ... improved ability
to keep entire objects on the same page [and] reduced file fragmentation,"
the company said.
"The updated Disk Manager's benefits span the software development
markets served by ExtremeDB," McObject CEO
Steve Graves said in a statement. "For applications that use persistent
storage, performance is improved transparently, without code changes or
explicit developer action, with further improvement possible through minor
application code changes."
In the area of security, the company has added a CRC
(Cyclical Redundancy Check) "on the database page level [that] detects
whether unauthorized modification to stored data has occurred ... [It] is also
employed to add reliability in the backup/restore feature of ExtremeDB
in-memory databases. CRC executes automatically
when a file is loaded to ensure the database has not been corrupted,
and when it is saved, to verify that the file has been written in its
entirety," the company explained.
McObject also added "the ability to restore a database from
transactions logged up to a specific date/time or according to an
'application-defined bookmark.' In the case of an accidental mass deletion or
change, this gives ExtremeDB the ability to restore to the last backup, and
then replay transactions up to, but not including, the error," the company
"Version 4.1 focuses on improvements in core things that ExtremeDB
does: managing data with breakthrough efficiency, adding safety and durability,
and streamlining software development and maintenance," Graves
