File Summary

Until recently, developing with Borland Delphi required using either the Borland Database Engine (BDE) and an ODBC driver or the Regatta Systems Titan Database Interface , hereafter referred to as Titan, to access Pervasive.SQL data. With the recent release of the newest Pervasive Direct Access Controls (PDAC), a developer has another, better option. Using the PDAC controls, experienced Delphi and C++ Builder developers could access all of the data aware controls while taking advantage of optimized data access controls. The PDAC controls consist of several VCL controls including PvTable, PvQuery, PvSession, PvSQLSession and others. This paper will focus on a description of the various components and migrating from code using BDE or Titan to the PDAC components. We will provide an overview of how to approach, implement, and deploy PDAC applications. Code changes from BDE and Titan to PDAC along with differences in functionality will be discussed. The sample included with this paper was developed using Pervasive.SQL V8, Borland Delphi 6 with Update 2, PDAC V8, and Titan Release 6.02i. The PDAC V8 components currently support Borland Delphi 5, 6 and 7 as well as C++ Builder 5 and 6. The PDAC portions of the Delphi samples used in this test were tested in all versions of Delphi however Titan is not supported in Delphi 7.
