Database access with Visual Basic (VB) has evolved from simple, local file-based systems to sophisticated, distributed enterprise frameworks. This report outlines the core technologies, connectivity methods, and modern practices for integrating databases into VB and VB.NET applications. 1. Historical Evolution of Data Access

The history of database access in Visual Basic is marked by a transition from the Jet Database Engine to more scalable, object-oriented models.

Represented a shift toward a platform-neutral model, using OLE DB to access various data sources, including SQL Server, Oracle, and even non-relational sources like Excel. 2. Core Connectivity Methods in VB.NET

Modern VB.NET applications primarily use the framework, which provides a disconnected architecture for high-performance data manipulation. Database Access with Visual Basic - Jeffrey P. McManus
