This article describes access control in Windows, which is the process of authorizing users, groups, and computers to access objects on the network or computer. Key concepts that make up access control are:
Computers that are running a supported version of Windows can control the use of system and network resources through the interrelated mechanisms of authentication and authorization. After a user is authenticated, the Windows operating system uses built-in authorization and access control technologies to implement the second phase of protecting resources: determining if an authenticated user has the correct permissions to access a resource.
Shared resources are available to users and groups other than the resource's owner, and they need to be protected from unauthorized use. In the access control model, users and groups (also referred to as security principals) are represented by unique security identifiers (SIDs). They're assigned rights and permissions that inform the operating system what each user and group can do. Each resource has an owner who grants permissions to security principals. During the access control check, these permissions are examined to determine which security principals can access the resource and how they can access it.
Security principals perform actions (which include Read, Write, Modify, or Full control) on objects. Objects include files, folders, printers, registry keys, and Active Directory Domain Services (AD DS) objects. Shared resources use access control lists (ACLs) to assign permissions. This enables resource managers to enforce access control in the following ways:
Object owners generally grant permissions to security groups rather than to individual users. Users and computers that are added to existing groups assume the permissions of that group. If an object (such as a folder) can hold other objects (such as subfolders and files), it's called a container. In a hierarchy of objects, the relationship between a container and its content is expressed by referring to the container as the parent. An object in the container is referred to as the child, and the child inherits the access control settings of the parent. Object owners often define permissions for container objects, rather than individual child objects, to ease access control management.
Permissions define the type of access that is granted to a user or group for an object or object property. For example, the Finance group can be granted Read and Write permissions for a file named Payroll.dat.
By using the access control user interface, you can set NTFS permissions for objects such as files, Active Directory objects, registry objects, or system objects such as processes. Permissions can be granted to any user, group, or computer. It's a good practice to assign permissions to groups because it improves system performance when verifying access to an object.
When you set permissions, you specify the level of access for groups and users. For example, you can let one user read the contents of a file, let another user make changes to the file, and prevent all other users from accessing the file. You can set similar permissions on printers so that certain users can configure the printer and other users can only print.
User rights are different from permissions because user rights apply to user accounts, and permissions are associated with objects. Although user rights can apply to individual user accounts, user rights are best administered on a group account basis. There's no support in the access control user interface to grant user rights. However, user rights assignment can be administered through Local Security Settings.
With administrator's rights, you can audit users' successful or failed access to objects. You can select which object access to audit by using the access control user interface, but first you must enable the audit policy by selecting Audit object access under Local Policies in Local Security Settings. You can then view these security-related events in the Security log in Event Viewer.
Microsoft Access's role in web development prior to version 2010 is limited. User interface features of Access, such as forms and reports, only work in Windows. In versions 2000 through 2003 an Access object type called Data Access Pages created publishable web pages. Data Access Pages are no longer supported. The Jet Database Engine, core to Access, can be accessed through technologies such as ODBC or OLE DB. The data (i.e., tables and queries) can be accessed by web-based applications developed in ASP.NET, PHP, or Java. With the use of Microsoft's Terminal Services and Remote Desktop Application in Windows Server 2008 R2, organizations can host Access applications so they can be run over the web.[35] This technique does not scale the way a web application would but is appropriate for a limited number of users depending on the configuration of the host.
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, do not require any add-ins or extensions (e.g., ActiveX and Silverlight).
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.
Users can create tables, queries, forms and reports, and connect them together with macros. Advanced users can use VBA to write rich solutions with advanced data manipulation and user control. Access also has report creation features that can work with any data source that Access can access.
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.
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]
I am a Certified Accountant and I started learning MSAccess in 2020 and its Language including SQL, VBA codes, and VBA FOrms and have used MS Access as my Database for its simplicity and its function to generate Table Queries. Combined with Excel as my Front for data entry and Unique Reports in which Access is limited. I created a complete set of Accounting Applications with Multi-User access that can be accessed over a network. With that, I created a Property Management Application to monitor the Property Plant and Equipments of a Company.
MsAccess is helpful for me because now my Journals, Ledgers, and General Ledgers are now accessible with no lag. Whereas before when I only used Excel it took long enough to generate data and if out of luck it will crash.
I was around for year 2K when all of a sudden retired cobol programmers were paid handsomly to fix things. It departments were never responsive to the business departments they were supposed to support. So there are a million business critical access databases that the it departments are not even aware of. I say this having worker for GE/NBC for 15 years.
I had created a number of databases in Access2 and office97 before I produced a generic MIS Management Information System for small business. The big problem I did have just before 2000 that set me back a while was making it an executable .exe. It had issues where different versions of office/msaccess had been installed on the users computer and Microsoft failed when it came to fixing this problem. It was fixed though, but not by Microsoft. Someone a lot cleverer than I wrote a script and offered it for sale. Sagekey software I believe was the scriptwriter and I gladly handed over the funds to get a license from them. It would be nice to see Microsoft getting a bit more serious about Access developments. They could begin by hiring the guy or gal from Sagekey that wrote the script which turned my mdb compiled mde files into exe.
My generic MIS fitted the needs of many small businesses back then, in fact the reason I landed here is that I have a need for it again, and wish to add some more features. I do hope that MS will invest some intelligent manpower into Access and develope it further.
I am sure that they would find that intelligence amongst the previous writers here or at SageKey maybe?
I for one would like very much the 4000+ hours work in Access that I have done, not go to waste!
