Topic: Microsoft Jet Database Engine


  
  Microsoft Jet Database Engine - Wikipedia, the free encyclopedia
Microsoft databases are organised into data "pages", which are fixed length (2 kB) data structures that divide up the database.
Jet passes the data retrieved for the query in a dynaset.
Jet 4 databases can be "upsized" (upgraded) to "an equivalent database on SQL Server with the same table structure, data, and many other attributes of the original database" if the developer has a copy of Microsoft Office 2000 Professional Edition via a Microsoft Access Upsizing Wizard utility.

 DataBase Engines
However, the 3.0 version of the Microsoft Jet database engine, which appeared in Microsoft Access 95, was completely rewritten as a 32-bit multithreaded process.
In querying situations, in particular, the difference between the two engines may be small, due to the fact that the Microsoft Jet engine was rewritten to use many of the performance techniques originally found in the FoxPro engine.
One reason SQL Server may outperform those engines is that its processing power resides on a high-end machine that is not restricted by bottlenecks such as slow network infrastructure (that is, NIC cards, slow protocol, and transport).

 VistaDB - VistaDB vs the Microsoft Jet engine and Access
Microsoft Access is not a data engine by itself, it is actually an application that uses the relies on the Microsoft Jet engine to perform the actual data storage and retrieval on the.MDB data files.
Microsoft Access was designed to be an end-user application and the.MDB Access database files is an inefficient storage format since it is designed to support non-essential data such as end-user forms, reports and modules.
Microsoft Jet is not intended to be used with high-stress, high-concurrency, 24x7 server applications, such as Web, commerce, transactional, and messaging servers.

 The Microsoft Jet Database Engine | Database Solutions for Microsoft Access | databasedev.co.uk
The Jet engine can be said to be comprised of two broad components:- a Data Definition Language to create and edit the data structures, and a Data Manipulation Language used for adding, editing and deleting data, and for querying.
Jet, as the brains behind MS Access, has proved to be exceptionally efficient in terms of generating databases quickly and easily - particularly for single users or small teams.
Access is the most popular desktop database application in the world today, and it’s popularity is due in no small part to the broad effectiveness of the Jet engine in accomplishing all necessary database handling tasks, from creation to security to multi-user support.

 Advanced Microsoft Jet SQL for Access 2000
Although this paper is focusing on the SQL syntax as it is implemented in the Jet 4.0 database engine, thanks to the stronger ANSI-92 compliance of Jet 4.0, many of the SQL statements are equally compatible and scalable to the SQL syntax implemented by the MSDE, and also by Microsoft SQL Server.
A procedure is a database object that you can use to execute an SQL statement that is based on values that are passed to it.
You decide to implement this with Jet's database password capability, but you do not want to show the user interface for database passwords that is currently in Access, because it only allows you to set or remove the database password.
