2. Problem Statement and Opportunity
Client Based Application
Developed in Vb6
Uses MS-SQL in back end
Web Based application
Developed in PHP
Uses MY-SQL in back end
ERP Customer Web Portal
Some situations where there is a need to sync databases from Different SQL
servers.
Opportunity for developing our own product for database
synchronization between MSSQL and MYSQL

?

3. Why MySQL
3 Dependability and versatility.
4 MySQL is the primary choice database for Web-based applications.
2 Simple to utilize and gives performance
1 MySQL is the world's most prominent open source database
5
The cost of running and keeping up MySQL is less as compare to alternate
databases.

4. Innovative Idea/solution
DB Sync Tool
Link Server+ T-SQL
Available Tools
Use MSSQL linked server for Data synchronization
Linked Servers allows you to connect to other database instances on the
same server or on another machine or remote servers.
The remote servers can be SQL Server, MYSQL , Oracle etc. which
means those databases that support OLE DB can be used for linking
servers
It allows SQL Server to execute SQL scripts on remote servers .
Insert , Delete and Update script for DB Sync

Collected details of both
database servers.
Identify tables and
columns for data sync
Information Collection
Software Installation & Setting
Coding
Execution
MySql Connector for
ODBC
ODBC DNS for MySql
Linking MySQL to
MSSQL server
Separate procedure for
each tables to perform
Insert , Update and
Delete operation.
Setting and Scheduling
SQL jobs for data sync

6. Advantages & Disadvantages Of Solution
Synchronize data that is available
via SQL queries
The SQL script can be saved into a
stored procedure, or run periodically
as a job for SQL Server.
Technical expert Required.
Creating such a SQL script is quite
tedious, because three scripts are
usually needed for each
table: INSERT, UPDATE,
and DELETE
Advantages Disadvantages

7. User Interface for
creating and scheduling
SQL jobs
Interface for Linking
MySQL server to
MSSQL server
Automatic Creation of
Procedure to perform
Insert , Update and
Delete operation
User Interface
for creation of
ODBC DNS for
MySQL
