Recording: https://pan.news/idna20200311 It’s dangerous to underestimate the impact of database design on the future of your Notes/Domino applications. It doesn’t matter if you are modernizing or migrating. Each path has to deal with its own challenges around platform dependencies or incompatibility in the source code. Having the code base at your fingertips is key to mastering these challenges before they turn into issues. Join Franz Walder for this webinar and learn how to identify the potential roadblocks. You will leave being able to apply these findings to your own project. They will help you avoid the complications so many others have run into. Project managers and developers alike will benefit from increased efficiency while reducing risk at the same time.

1. Make Your Data Work For You
Don’t end up in a ditch

Why you should care

7. Why you should care

8. Why you should care
clean up → low-hanging → analyze complexity /
unused DBs fruit re-develop apps /
change platforms

9. Why you should care
clean up → low-hanging → analyze complexity /
unused DBs fruit re-develop apps /
change platforms

10. Why you should care
clean up → low-hanging → source code
unused DBs fruit matters

11. Why you should care
clean up → low-hanging →  analyze complexity
unused DBs fruit  re-develop apps
 change platforms
 ...

12. Questions we hear a lot
• What is complex and what is not?
– How complex is my special database?
– How does the complexity of applications compare?
• What are roadblocks for my target scenario?
– Are there hard-coded references in my code?
– Are there design or code elements that may cause issues?
• What will it cost to migrate or modernize an application?
– Are there standard transformation paths?
– What kind of developer resources will I need?

13. Shout-out to …
… Code Similarity!
– Only 5-10% of your source code might be unique!
– Webinar #2 of this series

14. Why you should care
What Code Similarity can do for you:
• Drastically reduce effort of (re-)development
• Change profile of development resources you need
• Uncover lost template inheritance
– Open standard transformation paths

15. Make Your Data Work For You
The technical foundation

16. Technical foundation
Two ugly truths:
• Two DBs with the Same Design Template
will not necessarily have the same design
• Two databases with the Same Replica ID
will not necessarily have the same design
→ You want to make a very conscious decision on what you analyze

17. Technical foundation
How do you analyze your code?
• Domino Designer
is a place to start
• Lacks flexibility
• Lacks enterprise
capabilities

18. DXL: Domino XML Language
18

19. Why DXL?
19
• You will need flexibility that only very few approaches can provide
– Regex is one of them
– Having a text file is a start
• You typically want to analyze more than one database
– (if not all)
• You do not only want to search for code, but e.g., count
– Forms, views, actions, agents …
– Lines of code (per programming language)
– …

20. How DXL?
20
• Use notepad or similar to take a first look
– (Yes, that might be painful)
• Use XSLT → HTML
– (e.g. Comprehensive XSLT for DB design @OpenNTF)
• Tools like e.g. LotusScript Manager or Source Sniffer from OpenNTF
– Stay away from Lotus Analyzer

Just because you don’t have enough Headaches already …

22. Just because you don’t have enough headaches already
22
Having to deal with Remarks in code:
– %REM … %ENDREM
– (no)code ‘(apostrophe)
– REM
– (no)code : REM
– REM "comments";
– REM "comments“ ;
– REM {comments} ;

23. Just because you don’t have enough headaches already
23
It’s great what kind of Flexibility we have (to deal with):
– Var = “123“
– Var = “123“
– Var=“123“
– Var=‘123‘
– Var=_
“123“
– Var=FullTrim(|
123
|)

24. Just because you don’t have enough headaches already
24
@DbLookup(class:cache; server:db; view; key; fieldName; keywords)
@DbLookup(class:cache; server:db; view; key; columnNumber; keywords)
Challenge and Opportunity:
• Find all @DbLookups (and @DbColumns, …)
• Only flag the ones pointing to “other” databases

25. Just because you don’t have enough headaches already
25
And here is what that regular expression could look like:
(?iw)
@db(column|lookup)s*?
((s*??"notes?"|s*??"?")[^;]*;
(?!(?!s*??".+??"|s*?S+s*?:s*??".+??")|
s*??"?"(s*?:s*??"?")?s*?;|s*?@dbnames*?;|
s*?@subsets*?(s*?@dbnames*?;s*?1s*?)s*?:
s*?@subsets*?(s*?@dbnames*?;s*?-1s*?))
[^;]*;[^;]*;[^)]*)
