Office 2010 uses "Microsoft Office 14.0 Access Database Engine Object" Office 2013 uses "Microsoft Office 15.0 Access Database Engine Object" Office 2016 uses "Microsoft Office 16.0 Access Database Engine Object" Recordset - Contains a group of records returned from the data source.ĩ) What is the difference between the DAO 3.6 and Database Engine Object references ? Workspace - Contains information about the current session and open databases.Ĭonnection - Contans information about the ODBS data source. This change also corresponded with a new file extension (.ACCDB) which replaced (.MDB).ĪCE is Microsoft's recommended approach when communciating with a Microsoft Access databaseĨ) Can you describe the main objects in DAO ? In Access 2007 the DAO interface was upgraded and renamed to ACE. In Access 2003 DAO was back as the default, and has been ever since. In Access 20 the default interface was replaced with ADO. The Jet database engine was superseded by MSDE which in turn was superseded by SQL Server Express.Ħ) What is the default interface used in Microsoft Access ?ĭAO was the default up until Access 2000. Provided a specific interface for accessing a Microsoft Access / Jet database. Introduced with Microsoft Access in 1994. The File DSNs are stored by default in the following location: Program Files\Common Files\Odbc\Data Sources folder. The ODBC driver must be installed locally. The file must contain the information required to connect to the desired data source. DSN extension (not in the Windows registry). Stored in the Windows registry under the following key: HKEY_LOCAL_MACHINE\Software\Odbc\Odbc.ini\Odbc Data sourcesįile DNS - This is a DSN that is stored in a text file with a. System DNS - This DSN must be created on the machine where the program is located. Stored in the Windows registry under the following key: HKEY_CURRENT_USER\Software\Odbc\Odbc.ini\Odbc Data sources User DNS - Only the user who created the DSN can see this and use it. These drivers can be managed from the ODBC Data Source Administrator dialog box.Ĥ) What does DNS stand for and how it used ?Ī data source name (DSN) is a data structure that contains the information about a specific database that an ODBC Driver needs in order to connect to it. You can have multiple ODBC drivers installed which can target different types of databases. You can also get ODBC drivers for data sources that are not databases (for example Workbooks, CSV files, etc)Ī database driver is a piece of software that is installed to allow communication between a client application and a database (or data source) that supports ODBC. This is an open industry standard interface API for accessing databases on different operating systems. It can be installed/downloaded from within Access though In Access 365 this is no longer installed by default. If it all goes horribly wrong, you can always delete the database and start again (or you can back it up like we did with our Music database earlier).If you have a question, please send it to us.ġ) Where can I find the Northwind Access database ? Open them in Design View and see how they've been designed. For example, open the Navigation Pane to see how the objects have been organized. Once the database has been installed, you can log in using one of the users provided. I used Northwind at the default location. Give the database a name and location and click Create. We'll now install the Northwind sample database.įrom the Welcome screen (or the File menu), enter northwind into the search field.
