Foil 6 JDBC 3 Tier Example

From Examples of JDBC -- Microsoft Access CPS616 -- Information Track of CPS -- Spring Semester 97. by Sangeeta Aggarwal,Tom Pulikal,Udayan Pravate(Nancy McCracken) *

"3 Tier" refers to the presence of a "middle tier" service between the client and the database server
Commands are send to the middle-tier first, which then sends the SQL to the database and returns results from the database to the client
Advantages are :
  • avoids installations of any vendor specific libraries(.so or .DLL files) at the client side
  • control over access and updates of database
