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. Analyze

2. Design

3. Migrate the Data

4. 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– Make sure to see Sergio’s New Features

Presentation, 11:00AM Tomorrow, 2001 or stop by the DEMOGrounds to see Release 1.6

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.”

Project Tracker

Project Tracker

Development– Existing Oracle HTML DB Studio application– Development: 0 hours – Tweaking: roughly 5 hours

Audience– Technical skill level

Existing Application– Existing application was Microsoft Project

Project Tracker

Integration with other Oracle apps– Utilize LDAP Groups for authentication– Working on Single Sign On thru Portal

What we use this app for– College-Wide technology project management

Why we converted to Oracle HTML DB– Needed a Development Language that is

understandable– Need accessible application

Project Tracker

Project Tracker Demo– Demo Update and Add– Demo Reports– Demo Admin

Strategic Planning

Strategic Planning

Development– Development Time: 4 hours– Customization & Tweaking: ~ 20 hours

Audience– LCC Executives– Board of Trustees

Existing App– None (users requested MS Access)

Strategic Planning

Integration with other Oracle apps– Utilize LDAP Groups for authentication– Working on Single Sign On thru Portal

What we use this app for– Strategic Planning is for LCC’s Drivers &

Initiatives– To ensure activities are consistent with common

goals– Allows the President to see what is happening in

real-time

Strategic Planning

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

Strategic Planning

Strategic Planning Demo– Demo Update and Add– Demo Reports– Demo Admin

“With Oracle HTML DB, we were able to quickly

build a collaborative tool which increased communication and awareness among

senior executives and the community.”

Strategic Renewal

Strategic Renewal

Development– Development roughly 1 hour– Tweaking roughly 5 hours

Audience– Low technical skill level

Existing Application– 8 ½” x 11” Paper

Strategic Renewal

Integration with other Oracle apps– Utilize LDAP Groups for authentication– Delivered the application through Portal via iFrames

What we use this app for– Gathering input from our executives– Introducing them to the benefits of this technology

Why we converted to HTMLDB– Need a Development Language that is understandable– Need instant feedback on data

Strategic Renewal

Strategic Renewal Demo– Demo Portal integration– Demo Excel integration– Update and Add– Demo Reports– Demo Admin

Summary

With Oracle HTML DB, Lansing Community College was able to:

– Save Money– (Start to) Remove MS Access– Build Applications we couldn’t before– Increase Productivity– Gain Prestige for the IT Department
