The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Compare productivity of data processing in pl/sql or external C application trough OCI

Asked by dilnab in Oracle 9.x, PL / SQL

Tags: oracle, 9i, pl/sql, oci

We need to make application processing a large data. What is more fast,
1. using PL/SQL and internal Oracle logic.
2. take this logic out of Database and process it in extarnal C/C++ application.
In 2-d way it will use OCI to access to database.
For example, processing of table with large amount of rows. When doing in first way, we need to make PL/SQL coursor, and run through all table, and change some fields of table. In the second way we will make OCI coursor and run through table using OCI coursor.
The reason that make us to take processing out from Database to external application is that logic realised in C/C++ more faster than in PL/SQL, but in this case we take all data through listener out of the database and return changed data into the database. But in PL/SQL all processing in the database. Can you make us some advice? Thank you.
