Course Benefits

This Delphi database training course emphasizes productivity, performance, and application integrity. You will use Delphi specific features such as visual form inheritance, data modules, tClientDataSet, the repository, cached updates etc. to drastically cut development time and create more reliable applications. You'll learn the four different ways of accessing data in Delphi - BDE, ADO, dbExpress (Delphi 6 and Kylix), and custom third party database solutions. You'll also learn how to publish data on the Web using CGI and WebBroker.

You Will Learn How To
  • Design and implement client server, desktop, and Internet database applications
  • Make good use of the database tools and components in Delphi to increase productivity
  • Program in standard SQL
  • Develop multi-table, multi-user apps employing a wide range of controls and tools
  • Manage database integrity violations in your Delphi application
  • Configure the BDE, ADO, and dbExpress
  • Peek under the hood of database applications using SQL Monitor
  • Use dbExpress to create database applications without using the BDE
  • Use dbGo (ADO) as an alternative to the BDE
  • Use TClientDataSet with the BDE and dbExpress
  • Publish data on the Web using CGI and WebBroker technologies
