Jet originally started in 1992 as an underlying data access technology that came from a Microsoft internal database product development project, code-named Cirrus. Cirrus was developed from a pre-release version of Visual Basic code and was used as the database engine of Microsoft Access. Tony Goodhew, who worked for Microsoft at the time, says
Remote Data Objects (abbreviated RDO) is an obsolete data access application programming interface primarily used in Microsoft Visual Basic applications on Windows 95 and later operating systems. [1] This includes database connection , queries, stored procedures, result manipulation, and change commits.
Similarly, some applications such as Visual Basic, ASP.NET, or Visual Studio .NET will use the Microsoft Access database format for its tables and queries. Microsoft Access may also be part of a more complex solution, where it may be integrated with other technologies such as Microsoft Excel , Microsoft Outlook , Microsoft Word , Microsoft ...
Since the Leszynski naming convention is a special form of Hungarian notation the same general advantages also apply to the Leszynski convention.. The use of distinctive prefixes makes your database self-documenting; when you see frmSales in VBA code, you will know that it references a form, and when you see curSales you will know that it is a Currency variable.
Jet stands for Joint Engine Technology and was a database engine used for Microsoft Access, Microsoft Exchange Server and Visual Basic. Jet was part of a Relational Database Management System (RDBMS) and offered a single interface that other software could use to access Microsoft databases.
Query by Example (QBE) is a database query language for relational databases. It was devised by Moshé M. Zloof at IBM Research during the mid-1970s, in parallel to the development of SQL . [ 1 ] It is the first graphical query language, using visual tables where the user would enter commands, example elements and conditions.
