2 Version 4.1 Improved Result Rendering Improved SQL queries Version 4.2 Optional Report Sample Optimized Auto- suggest

3 3 Database ServerWeb ServerClient Machine Open a ConnectionLoad Results Calculations Arranging Data Execute the Query Render the Results Compute Functions

4 4 Database ServerWeb Server Client Machine Pentium 4® or higher 2 GB recommended Disk Space: 500 MB Google Chrome Firefox

5 5 Database Server Open a Connection Do you have enough database licenses? Has Informer reached its connection maximum?

6 6 Database Server Open a Connection Do you have enough database licenses? UniData : LISTUSER UniVerse : CONFIG

7 7 Database Server Open a Connection Has Informer reached its connection maximum?

8 8 Database Server Open a Connection Has Informer reached its connection maximum?

9 9 Database Server Execute the Query Do you have initialization subroutines? Are you selecting on a virtual field from large dataset? Are you returning a large number of rows?

10 10 Database Server Execute the Query Do you have initialization subroutines? UniData / UniVerse: Consider purchasing a connection pooling license to reduce initialization subroutine overhead.

11 11 Database Server Execute the Query Are you selecting on a virtual field from large dataset? PERSON FILE 60,000 RECORDS SELECT PERSON WITH AGE = 185,000 RECORDS SELECT PERSON WITH NAME = “JASON”50 RECORDS 1 MINUTE 10 SECONDS = 1 MINUTE : 10 SECONDS TOTAL

12 12 Database Server Execute the Query Are you selecting on a virtual field from large dataset? PERSON FILE 60,000 RECORDS SELECT PERSON WITH NAME = “JASON”500 RECORDS SELECT PERSON WITH AGE = 1850 RECORDS 20 SECONDS 2 SECONDS = 22 SECONDS TOTAL

13 13 Database Server Execute the Query / Loading Results Are you returning a large number of rows? Database ServerWeb Server

14 14 Web Server Calculations Do you have calculated columns in your report? What is the nature of the calculated columns?  Does it loop through an iteration?  Does it check an if-then-else statement?  Does it run a subroutine or function?

15 15 Web Server Calculations Do you have calculated columns in your report? 60,000 RECORDS 10 ITERATIONS 600,000 CALCULATIONS! X =

16 16 Web Server Arranging Data Is your data Sorted? Are you normalizing on multi-values? Is your data being grouped?

17 17 Web Server Compute Functions Are you subtotaling/averaging groups?

18 18 Rendering the Results Again, is your data being grouped? Are you displaying all records instead of a paged set? Do you have a large number of columns? Client Machine

19 19 Rendering the Results Again, is your data being grouped? Group Headers are not shown in pages! 10,000 Groups = 10,000 Items to render! Client Machine

20 20 Rendering the Results Are you displaying all records instead of a paged set? Paged: Not Paged: Client Machine

21 21 Rendering the Results Do you have a large number of columns? 10,000 Rows x 10 Columns = 100,000 Cells 10,000 Rows x 20 Columns = 200,000 Cells Twice the information, Twice the render time! Client Machine

22 Thank you! Any questions?
