1. UniData to SQL Conversion Don’t lose your Informer investment…
PRESENTER: Tim Nicholson | Director of Customer Services, Entrinsik| March 6, 2012

2. Problem Datatel clients are migrating from UniData to SQL
Large investment in Informer reports
Unidata is to SQL what oil is to water
Different structure
Different query language

3. Solution
Write a tool that migrates as much of the mapping and report metadata as possible.

4. Challenges
Multivalues
Computed Columns / I-Descriptors

5. UniData SQL Multivalues PERSON PERSON @ID FIRST.NAME LAST.NAME
PERSON_LS
PERSON_ID
POS
WHERE_USED
WHERE.USED
PEOPLE_
PERSON_ID
POS
PERSON_ _ADDRESSES
PERSON_ _TYPES
PERSON. .ADDRESSES
PERSON. .TYPES

6. Computed Columns/I-Descriptors
Become T-SQL functions
Not associated with a table
Take primary key as parameter
Once mapped, treat like any other property
Available in 4.3
Can use in SQL Block (4.2.8) as well

7. Limitations
Cannot convert
TCL/ECL
Select/Returning
Remote links
