It is similar to Visual Basic 6. To create a richer, more efficient and maintainable finished product with good error handling, most professional Access applications are developed using the VBA programming language rather than macros, except where web deployment is a business requirement.
In the database container or navigation pane in Access and later versions, the system automatically categorizes each object by type e. Many Access developers use the Leszynski naming convention , though this is not universal; it is a programming convention, not a DBMS-enforced rule. Developers deploy Microsoft Access most often for individual and workgroup projects the Access 97 speed characterization was done for 32 users.
Databases under 1 GB in size which can now fit entirely in RAM and simultaneous users are well within the capabilities of Microsoft Access. Disk-intensive work such as complex searching and querying take the most time. 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 , [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. In July , Microsoft acknowledged an intermittent query performance problem with all versions of Access and Windows 7 and Windows Server R2 due to the nature of resource management being vastly different in newer operating systems.
In earlier versions of Microsoft Access, the ability to distribute applications required the purchase of the Developer Toolkit; in Access , and Access the “Runtime Only” version is offered as a free download, [44] making the distribution of royalty-free applications possible on Windows XP, Vista, 7 and Windows 8.
Microsoft Access applications can adopt a split-database architecture. The single database can be divided into a separate “back-end” file that contains the data tables shared on a file server and a “front-end” containing the application’s objects such as queries, forms, reports, macros, and modules.
The “front-end” Access application is distributed to each user’s desktop and linked to the shared database. Using this approach, each user has a copy of Microsoft Access or the runtime version installed on their machine along with their application database. This reduces network traffic since the application is not retrieved for each use. The “front-end” database can still contain local tables for storing a user’s settings or temporary data.
This split-database design also allows development of the application independent of the data. One disadvantage is that users may make various changes to their own local copy of the application and this makes it hard to manage version control. When a new version is ready, the front-end database is replaced without impacting the data database. Microsoft Access has two built-in utilities, Database Splitter [46] and Linked Table Manager, to facilitate this architecture.
Linked tables in Access use absolute paths rather than relative paths, so the development environment either has to have the same path as the production environment or a “dynamic-linker” routine can be written in VBA. For very large Access databases, this may have performance issues and a SQL backend should be considered in these circumstances. To scale Access applications to enterprise or web solutions, one possible technique involves migrating to Microsoft SQL Server or equivalent server database.
A client—server design significantly reduces maintenance and increases security, availability, stability, and transaction logging. This feature was removed from Access A variety of upgrading options are available.
The corresponding SQL Server data type is binary, with only two states, permissible values, zero and 1. Regardless, SQL Server is still the easiest migration. Retrieving data from linked tables is optimized to just the records needed, but this scenario may operate less efficiently than what would otherwise be optimal for SQL Server.
For example, in instances where multi-table joins still require copying the whole table across the network. The views and stored procedures can significantly reduce the network traffic for multi-table joins. Finally, some Access databases are completely replaced by another technology such as ASP. NET or Java once the data is converted. 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 and again in Access In many cases, developers build direct web-to-data interfaces using ASP. NET, while keeping major business automation processes, administrative and reporting functions that don’t need to be distributed to everyone in Access for information workers to maintain.
Microsoft Access applications can be made secure by various methods, the most basic being password access control; this is a relatively weak form of protection. A higher level of protection is the use of workgroup security requiring a user name and password. Users and groups can be specified along with their rights at the object type or individual object level.
This can be used to specify people with read-only or data entry rights but may be challenging to specify. A separate workgroup security file contains the settings which can be used to manage multiple databases. Databases can also be encrypted.

The Microsoft Access Runtime version differs from the retail version in several ways: All design-related user interfaces are either removed or disabled Database and macro windows are hidden Filter By Form, Filter By Selection, and Advanced Filter windows are hidden This means your users only use the forms and reports you create and do not work directly with the tables, queries, etc.
Users cannot create their own Microsoft Access databases or modify the object designs in the database s you give them There is no Design View. Your users cannot modify your objects including queries and reports. The VBA editor is not included.
Your users cannot view or modify module code. Note that spell checking is available if the user has that version of Office installed.
Crashes in your VBA code are not handled. Make sure you implement error handling throughout your application. No Access help file Make Sure You Have Error Handling for Runtime Distributions Because users of the runtime version do not have the design surfaces, it’s important that any MS Access application you distribute with the runtime has a robust global error handler in place for all procedures.
You can download them from here: Office and Access So for software like Ham Radio Deluxe – it’s a problem that we can’t fix as long as the database is running on Access. As mentioned before, we get customers complaining that Logbook is slow. When we investigate this, it’s pretty easy to find that this is the cause of the problem.
A while back, I wrote a post on our peer support forums entitled – ” For those reporting “slow” performance of Logbook. Here are the steps I advised customers to take if they feel that Logbook performance is slow:. In Logbook I moved all my data out of that and into the logs shown below it to improve the performance of my own installation of Ham Radio Deluxe. So if this applies to you Finally, given that this is part of the operating system, it’s not something we can change with our installation of Ham Radio Deluxe.
That is – we can’t fix the version of Jet. We can provide guidance about how to fix it. That said, we DO want to move away from Access and Jet for a number of reasons. Reason 1 – all the problems referenced above.
