I have just joined an in flight project and find the lead data modeler has created a name value pair data model.
The reason given was flexibility of data model considering some records can have as many as 900 attributes. The .Net application team seem to be loving it, as they can code everything with very few tables in mind.
I feel the model is difficult to query, difficult to load and difficult to syndicate and in all likelyhood will suffer from poor performance.
I just posted a complete integrated set of tools to manage, monitor and tune the Oracle database.
It is free, no registration or email is required. I will just appreciate any kind of feedback to make it better.
The package comprises the following topics:
This section allows you to view and maintain virtually all database objects, including partitioned tables and materialized views. It also includes a function to view inter-dependency between objects.
This section allows you manage users and security.
Matthew Morris (who makes many constructive and knowledgeable contributions to the forum) has written a series of study guides for the OCA/OCP exams. I asked him if I could have a copy of one to review. The result: it's very good. This is a copy of the review I put up on Amazon.
The other day, I was asked how to move a table from one schema to another. The answer, as we all know, is "you can't do that: you have to create a new table as a copy of the old one, or use export/import. It will take a long long time." Not true.

I've been asked by the publishers to review "Oracle Database 11g Release 2: Performance Tuning Tips and Techniques" by Richard Niemiec of TUSC. Conclusion: it is good but not perfect. This is an extended version of the review I put up on Amazon.

Dependency Oracle schema is the place where all the Database objects get stored. This make a room for the entire set of objects under the Category of Data Storage ( Tables, Views) and Data Access (Stored Procedure ,Functions ,Packages and Triggers) .These Objects make a reference across all these objects to form the application.This is known as dependency.
Conventional Dependency Model If an Object B is being referrd from object A (ie Object A refers another Object B) , Object A is known as Dependant Object and Object B is Known as referenced Object.
It gives me great pleasure and honour to announce my upcoming book Oracle Advanced PL/SQL Developer Professional Guide with Pact Publishers. The book 'Oracle Advanced PL/SQL Developer Professional Guide' is focussed on the preparation of OCP (1Z0-146) examination. The book doesn't restricts its scope to the examination but aims to strengthen the advanced concepts in Oracle 11g PL/SQL.
The book has been reviewed by Oracle ACEs Kamran Agayev, Ronald Rood and Mohan Dutta. It is under production and is expected to be released by May, 2012.
