ORACLE HTML DB
Microsoft Access
Migration
Access Password “Recovery”
 About $15
 Many variations
 Also available for
other MS Office
Components
 If your data is worth
less than $15, MS
Access is a good
place to store it
Four Steps to a Successful
Migration
1.
2.
3.
4.
Analyze
Design
Migrate the Data
Migrate the Application
1) Analyze
 MOST IMPORTANT STEP
–
If this is not done or done poorly, you will have a
poorly designed HTML DB Application!
 Analyze both the Data Model and Application
 Decide if you can consolidate several MS
Access Applications into a single HTML DB
Application
2) Design
 Application Design
–
–
–
–
Many constructs of MS Access do not translate to
the web
There is not necessarily a 1-to-1 relationship
between an MS Access form and an HTML DB
Form
HTML DB Reports can replace several MS
Access Reports
Forms built in MS Access to manage LOVs can
be managed as LOV natively in HTML DB
2) Design
 Database Design
–
–
–
–
Good database design is fundamental to a good
application
Many MS Access Applications are written by
people who don’t know a lot about data modeling
HTML DB wizards prefer numeric Primary Keys
automatically populated via a Trigger
Normalize data where appropriate
3) Migrate the Data
 Use the Oracle
Migration Workbench to
move the data from
Access to Oracle
 If you need to change
the data model:
–
–
Migrate ALL of the
tables to Oracle
Make changes on the
Oracle side via SQL
Workshop
4) Migrate the Application
 Create an HTML DB Workspace based on the
schema that the Migration Workbench created
 Create an Application on this Workspace
 Use the Wizards to quickly re-create the
Forms and Reports in HTML DB
Southwind Wholesalers
 Conversion of MS Access Northwind Traders
Sample Application
 Took about a day to fully convert all data,
reports, business rules
 HTML DB application has more functionality
–
–
–
–
Drill Down Links
User Security
Data Concurrency
Scalability
 Available on HTML DB Studio
(http://htmldb.oracle.com/studio)
Summary
 It’s all about the data model!
 A little planning will go a long way
 There is more than one way to migrate an
application – keep the client involved so as to
not build something they will not want/like
 Master-Detail wizard is coming in version 1.6

ORACLE HTML DB
HTML DB at LCC
Why did LCC Select Oracle
HTML DB?
 Reusable and accessible format
–
–
Underlying Oracle Database
Easily access other Oracle apps data
 Web-based
–
–
Many apps moving to the web
Considered more user friendly than forms
 Cost
–
–
–
No additional software required
10g Companion CD
Utilize non-developers
Why did LCC Select Oracle
HTML DB?
 Eliminate “Shadow Systems”
–
–
4000 + Microsoft Access databases
Shadow Systems Required additional hardware
(servers)
 Quickly build applications
–
–
Wizards
Re-Use Existing apps or parts of existing apps
Improved User Feedback
 Prior to Oracle HTML DB, Users would create
applications and then ask IT to
manage/fix/own them
 After Oracle HTML DB, users are proactively
seeking out IT for application development
assistance
–
–
Much More Manageable
Controlled Development Environment
“We have been able
to develop and
deploy three
production systems
in two to three
weeks.”

 Why we converted to HTMLDB
–
–
–
Did not want to build new applications in MS
Access as it is too difficult to deploy and manage
Ability for End Users to Quickly access
applications via Portal
Easier to use Oracle HTML DB than MS Access,
as user base is not very technical
