Hi

 

We are trying to do a Query and= index modeling exercise by attempting to MAP a significant portion of our Product’s Queries to corresponding basic Standard SQLs for SMALL, MEDIUM, BIG & Very BIG Tables using different= Types of Indexes, as mentioned below:-

 

Our Product is a Hybrid Banking Application.

 

Curre= ntly mapping has been done to basic Standard Queries which use a Single Table= only:-

 

•       = ;   Basic Standard SQLs containing SELECT,= UPDATE, DELETE of the following types have been mapped:-

–       = ;  Point (returns 1 row)

–       = ;  Multipoint (returns more than 1= row)

–       = ;  Range scan (where Clause has a range specification)

–       = ;  Prefix and suffix

–       = ;  Conjunctive point (where Clause using all= the key fields of the  unique index, up to 3 fields)

–         Extremal=

 

•       = ;   INSERT

 

•       = ;   Additionally

–         Update using= ROWID

–       = ;  Select using ROWNUM

 

Types of Indexes Used:-

      •       = ;   Normal index

•       = ;   Index organized table

•       = ;   B+ tree cluster

•       = ;   Hash cluster

 

Qs. 1= How to approach, map & define standard SQLs having a JOIN between multiple Tables (i.e. 2, 3 Tables)

 

Qs. 2= How do we extend this to Sub-queries, In-line queries= etc.?

 

Qs. 3 Any Docs, Links, Books on similar work done before?

 

Thanks indeed
