DBMS (DataBase Management Systems) and DBMS Vendors
Much of our research deals with database management
systems (DBMS) and closely related subjects, such as text search
and business intelligence.
Some of our opinions are below.
Also linked are some of our articles on Oracle, the leading DBMS
The Real Point of Oracle10g Manageability
The initial marketing of Oracle10g revolves around grid
computing. But grid computing was not the
design focus of this Oracle release, nor will it provide the main user benefits of this
upgrade. Rather, the main emphasis of Oracle
10g is to narrow the gap with Microsoft in the area of manageability.
Text Search: General-Purpose
DBMS vs. Specialty Search Engines
For most text search applications, we favor using DBMS
as the underpinnings, rather than specialized search engines. DBMS are competitive with search engines
text-specific features, and superior in manageability.
This implementation choice also supports tight relational/text integration,
which is important in a surprisingly broad range of applications.
Security, Forensics, and Privacy in the Database
DBMS offer powerful, flexible security features. These deserve more use than they get, in
application areas ranging from OLTP to text search.
Most important, these features can go a long way toward providing the
privacy assurances that will be needed for database integration projects in health care
and homeland security.
How Oracle Does OLAP
Oracle has rather thoroughly integrated OLAP (OnLine
Analytic) processing into its core database. OLAP
cubes are stored as LOBs (Large OBject data). These
are then indexed by a descendant of the Express engine, analogous to the way Oracle
handles text data.
Besides the Express language, the SQL Model clause
offers an interesting additional way to get at OLAP data.
However, it is not yet widely used.
Oracle Should and Well May Acquire BEA Systems
Highly controversial when first published, our view of a
possible Oracle/BEA merger is now more widely shared.
And our greatest reservation, Oracles long-standing Not Invented
Here syndrome, has been overtaken by subsequent events.
