Jet combined three primary subsystems; an ISAM-based database engine (also named Jet, confusingly), a C-based interface allowing applications to access that data, and a selection of driver dynamic-link libraries (DLL) that allowed the same C interface to redirect input and output to other ISAM-based databases, like Paradox and xBase. Jet ...
OLE DB separates the data store from the application that needs access to it through a set of abstractions that include the datasource, session, command, and rowsets. This was done because different applications need access to different types and sources of data, and do not necessarily want to know how to access functionality with technology ...
One can set up joins by clicking and dragging fields in tables to fields in other tables. Access allows users to view and manipulate the SQL code if desired. Any Access table, including linked tables from different data sources, can be used in a query. Access also supports the creation of "pass-through queries".
The Microsoft SQL Server Network Library, a proprietary access method specific to Microsoft SQL Server, is also included in the MDAC. Developers of Windows applications are encouraged to use ADO or ADO.NET for data access, the benefit being that users of the application program are not constrained in their choice of database architecture except ...
While netlib's job is to ferry data between the two computers through the underlying network protocol, db-lib provides an API to the client program, and communicates with the server via netlib. db-lib sends to the server a structured stream of bytes meant for tables of data, hence a Tabular Data Stream.
TABLE 0,1 "EXCEL" VECTORS → the number of columns follows as a numeric value 0,2 → '0' indicates that it's a numeric type, '2' since we have 2 columns "" TUPLES → the number of rows follows as a numeric value 0,3 → '0' indicates that it's a numeric type, '3' since we have 3 rows "" DATA → after a dummy 0 numeric value, the data for ...
As an example, VBA code written in Microsoft Access can establish references to the Excel, Word and Outlook libraries; this allows creating an application that – for instance – runs a query in Access, exports the results to Excel and analyzes them, and then formats the output as tables in a Word document or sends them as an Outlook email.
Bi-directional replication with MS SQL Server. Microsoft Access versions from Access 2000 to Access 2010 included an "Upsizing Wizard" which could "upsize" (upgrade) a Jet database to "an equivalent database on SQL Server with the same table structure, data, and many other attributes of the original database". Reports, queries, macros and ...
