Want the book of database design

Question

I am interesting how to develop a database(logical and physical). Do you have any good book to recommend to me?
Thank you

hi..
better way to go for stored procedures..
Stored procedures can return result sets, i.e. the results of a SELECT statement. Such result sets can be processed using cursors by other stored procedures by associating a result set locator, or by applications. Stored procedures may also contain declared variables for processing data and cursors that allow it to loop through multiple rows in a table. The standard Structured Query Language provides IF, WHILE, LOOP, REPEAT, and CASE statements, and more. Stored procedures can receive variables, return results or modify variables and return them, depending on how and where the variable is declared.
Advantages
A variety of advantages can be obtained through the use of stored procedures.
[edit] Pre-compilation of SQL statements
SQL statements implemented as stored procedures may run faster in some circumstances, as they can be pre-compiled. Execution plans for compiled statements can be stored in the database, together with the procedure. That removes the SQL compilation overhead that is typically required in situations where software applications send inline SQL queries to a database.
Pre-compilation implies that the execution plan may not be optimal in all cases. Some information is typically unavailable at the time that the execution plan is generated, for example, the exact values used in predicates. Out-dated statistics are another potential source for suboptimal plans.
The performance benefits of pre-compilation of stored procedures are largely exaggerated. Embedded static SQL is also pre-compiled and, therefore, offers the same advantages without stored procedures. Most database systems implement statement caches to avoid repetitive compilation of dynamic SQL statements.
