We all have limits, and an Access database is no exception. For example, an Access database has a size limit of 2 GB and can't support more than 255 concurrent users. So when it's time for your Access database to go to the next level, you can migrate to SQL Server. SQL Server (whether on-premises or in the Azure cloud) supports larger amounts of data, more concurrent users, and has greater capacity than the JET/ACE database engine. This guide gives you a smooth start to your SQL Server journey, helps preserve Access front-end solutions you created, and hopefully motivates you to use Access for future database solutions. The Upsizing Wizard was removed from Access in Access 2013, so now you can use the Microsoft SQL Server Migration Assistant (SSMA). To successfully migrate, follow these stages.
Improved security Using a trusted connection, SQL Server integrates with Windows system security to provide a single integrated access to the network and the database, employing the best of both security systems. This makes it much easier to administer complex security schemes. SQL Server is the ideal storage for sensitive information such as Social Security numbers, credit card data, and addresses that are confidential.

Tip If possible, use a stand-alone version of Access. If you can only use Microsoft 365, then use the Access 2010 database engine to migrate your Access database when using SSMA. For more information, see Microsoft Access Database Engine 2010 Redistributable.
This issue occurs when you try to use Access 2013 or later version of Microsoft Access to open an Access 97 database. To work around this issue, use a pre-Access 2013 version of Access to save the Access 97 database as an .accdb file:
I needed both the 32-bit and the 64-bit adapters to cover my various use cases. I started by installing the 64-bit Microsoft Access Database Engine 2010 Redistributable. If you have ever attempted this, you know there is a secret. You cannot install the 2010 Access database engine with a different processing architecture (bittedness) from your Office install (or install both versions of the 2010 Access database engine) without a workaround. If you try, you will get an error message.
Microsoft Access is a database management system (DBMS) from Microsoft that combines the relational Access Database Engine (ACE) with a graphical user interface and software-development tools (not to be confused with the old Microsoft Access which was a telecommunication program that provided terminal emulation and interfaces for ease of use in accessing online services such as Dow Jones, Compuserve and electronic mailbox in the 1980s[3][4]). It is a member of the Microsoft 365 suite of applications, included in the Professional and higher editions or sold separately.
Microsoft's first attempt to sell a relational database product was during the mid 1980s, when Microsoft obtained the license to sell R:Base.[7] In the late 1980s Microsoft developed its own solution codenamed Omega.[8] It was confirmed in 1988 that a database product for Windows and OS/2 was in development.[9][10] It was going to include the "EB" Embedded Basic language,[8] which was going to be the language for writing macros in all Microsoft applications,[11] but the unification of macro languages did not happen until the introduction of Visual Basic for Applications (VBA). Omega was also expected to provide a front end to the Microsoft SQL Server.[12] The application was very resource-hungry, and there were reports that it was working slowly on the 386 processors that were available at the time.[13] It was scheduled to be released in the 1st quarter of 1990,[14] but in 1989 the development of the product was reset[7][15] and it was rescheduled to be delivered no sooner than in January 1991.[16] Parts of the project were later used for other Microsoft projects: Cirrus (codename for Access) and Thunder (codename for Visual Basic, where the Embedded Basic engine was used).[7][8] After Access's premiere, the Omega project was demonstrated in 1992 to several journalists and included features that were not available in Access.[17]
Microsoft Access 2013 offers traditional Access desktop applications plus a significantly updated SharePoint 2013 web service.[25] The Access Web model in Access 2010 was replaced by a new architecture that stores its data in actual SQL Server databases. Unlike SharePoint lists, this offers true relational database design with referential integrity, scalability, extensibility and performance one would expect from SQL Server.[26] The database solutions that can be created on SharePoint 2013 offer a modern user interface designed to display multiple levels of relationships that can be viewed and edited, along with resizing for different devices and support for touch. The Access 2013 desktop is similar to Access 2010 but several features were discontinued including support for Access Data Projects[clarification needed] (ADPs), pivot tables, pivot charts, Access data collections, source code control, replication, and other legacy features.[27] Access desktop database maximum size remained 2 GB (as it has been since the 2000 version).
Access 2010 allows databases to be published to SharePoint 2010 web sites running Access Services. These web-based forms and reports run in any modern web browser. The resulting web forms and reports, when accessed via a web browser, don't require any add-ins or extensions (e.g., ActiveX and Silverlight).
Access 2013 can create web applications directly in SharePoint 2013 sites running Access Services. Access 2013 web solutions store its data in an underlying SQL Server database which is much more scalable and robust than the Access 2010 version which used SharePoint lists to store its data.
A compiled version of an Access database (file extensions .MDE /ACCDE or .ADE; ACCDE only works with Access 2007 or later) can be created to prevent users from accessing the design surfaces to modify module code, forms, and reports. An MDE or ADE file is a Microsoft Access database file with all modules compiled and all editable source code removed. Both the .MDE and .ADE versions of an Access database are used when end-user modifications are not allowed or when the application's source code should be kept confidential.
The original concept of Access was for end users to be able to access data from any source. Other features include: the import and export of data to many formats including Excel, Outlook, ASCII, dBase, Paradox, FoxPro, SQL Server and Oracle. It also has the ability to link to data in its existing location and use it for viewing, querying, editing, and reporting. This allows the existing data to change while ensuring that Access uses the latest data. It can perform heterogeneous joins between data sets stored across different platforms. Access is often used by people downloading data from enterprise level databases for manipulation, analysis, and reporting locally.
Access 2013 offers the ability to publish Access web solutions on SharePoint 2013. Rather than using SharePoint lists as its data source, Access 2013 uses an actual SQL Server database hosted by SharePoint or SQL Azure.[33] This offers a true relational database with referential integrity, scalability, maintainability, and extensibility compared to the SharePoint views Access 2010 used. The macro language is enhanced to support more sophisticated programming logic and database level automation.[26]
As data from a Microsoft Access database can be cached in RAM, processing speed may substantially improve when there is only a single user or if the data is not changing. In the past, the effect of packet latency on the record-locking system caused Access databases to run slowly on a virtual private network (VPN) or a wide area network (WAN) against a Jet database. As of 2010,[update] broadband connections have mitigated this issue. Performance can also be enhanced if a continuous connection is maintained to the back-end database throughout the session rather than opening and closing it for each table access.[citation needed]
In previous versions of Access, including Access 2010, databases can also be converted to Access Data Projects (ADP) which are tied directly to one SQL Server database. This feature was removed from Access 2013. ADP's support the ability to directly create and modify SQL Server objects such as tables, views, stored procedures, and SQL Server constraints. The views and stored procedures can significantly reduce the network traffic for multi-table joins. SQL Server supports temporary tables and links to other data sources beyond the single SQL Server database.
Finally, some Access databases are completely replaced by another technology such as ASP.NET or Java once the data is converted. However any migration may dictate major effort since the Access SQL language is a more powerful superset of standard SQL. Further, Access application procedures, whether VBA and macros, are written at a relatively higher level versus the currently available alternatives that are both robust and comprehensive. Note that the Access macro language, allowing an even higher level of abstraction than VBA, was significantly enhanced in Access 2010 and again in Access 2013.
DBCON / Multiconnect uses the Microsoft SQL Server Native Client Software (SNAC) to establish a connection to the remote SQL Server instance. The Microsoft SQL Server Client Software for Windows consists of several *.dll files. For long time it was available for Windows platforms only. Recently, Microsoft ported its ODBC SQL Native Access driver to Linux. For this reason heterogeneous Linux/Windows scenarios are now possible. DBCON utilizes the SAP ABAP stack to access the external databases so your system requires at least one ABAP-stack-based SAP Application Server running on Windows or Linux x86_64.
UDConnect uses a JDBC (Java Database Connectivity) driver to establish a connection to the remote SQL Server instance. The JDBC driver consists of one or more *.jar files and can be used on Windows, Unix and Linux operating systems. As UDConnect utilizes the J2EE engine of the SAP Application server to access the external databases you need to have at least one Java-Stack-based SAP Application Server in your SAP system in order to use UDConnect. 2ff7e9595c
