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.

Please explain how to calculate table size by hand (using the provided example)

Asked by marcoullisp in Databases Miscellaneous

Tags: size, calculate, table, how

Hi experts...

here is the example I have for you:

http://www.marcoullis.com/EE_DB/

I am trying to learn how to calculate table size, and to be honest I need a dumbed down explanation. Other explanations I have found on the EE website are too complicated. No need to calculate all the tables provided, just if someone could run through one table calculation on the "Tenants.sql" database, and one on the "Rental_Unit" database that would be real cool.

Specifically:

1. The "tbl_Tenant" table in database "Tenants.sql
2. The "tbl_Rental_Unit" in database "Rental_Unit.sql"

The dbms is MySQL. The ERD's are for two database that form the backend of a content management system for a large rental apartment corporation in Washington DC... its an exercise from my school book. I am not interested in specific dbms handling of table calculation, just the theory behind how to calculate table size. Preferably a step-by-step approach that a norom (backwards moron) like myself could understand.

There are no variable length fields, just fixed length.

The "tbl_Rental_Unit" table employs the use of data blobs for all the columns named "Schema_". These are very large pictures of schematics...

Thats all I have... please help...
