TransCAD is the only software package that fully integrates GIS withdemand modeling and logistics functionality. This makes it possible for models to be much more accurateand efficient.For example, network distances and travel times are based on the actual shape of theroad network and a correct representation of highway interchanges. Also,with networks, you can specify complex road attributes such as truckexclusions, delays at intersections, one-way streets, and constructionzones. Further, data preparation is greatly facilitated and the databaseand visualization capabilities catch errors before they cause problems.
TransCAD allows you to identify the location oftransportation features as a distance from a fixed point along a route.TransCAD can display and analyze these data sets without conversion, andincludes dynamic segmentation functions to merge and analyze multiplelinear-referenced data sets. This makes TransCAD a natural choice for:

The Microsoft Access Database Engine 2016 Redistributable 64-bit is not installed on the machine.
Microsoft .NET Desktop Runtime version 6.0.5 or later is not installed.
In some cases, projects may not open that have data in an incompatible version of Excel. Depending on the version of Microsoft Office, it may be necessary to perform a silent install of both 32-bit .NET Runtime and 32-bit Access DB driver, or sometimes one or the other, see the Guide to connecting to Excel files in ArcGIS Pro.
Backs up a complete SQL Server database to create a database backup, or one or more files or filegroups of the database to create a file backup (BACKUP DATABASE). Also, under the full recovery model or bulk-logged recovery model, backs up the transaction log of the database to create a log backup (BACKUP LOG).
Specifies a complete database backup. If a list of files and filegroups is specified, only those files and filegroups are backed up. During a full or differential database backup, SQL Server backs up enough of the transaction log to produce a consistent database when the backup is restored.
Specifies a backup of the transaction log only. The log is backed up from the last successfully executed log backup to the current end of the log. Before you can create the first log backup, you must create a full backup.
Used to create an Azure snapshot of the database files when all of the SQL Server database files are stored using the Azure Blob Storage. For more information, see SQL Server Data Files in Microsoft Azure. SQL Server Snapshot Backup takes Azure snapshots of the database files (data and log files) at a consistent state. A consistent set of Azure snapshots make up a backup and are recorded in the backup file. The only difference between BACKUP DATABASE TO URL WITH FILE_SNAPSHOT and BACKUP LOG TO URL WITH FILE_SNAPSHOT is that the latter also truncates the transaction log while the former does not. With SQL Server Snapshot Backup, after the initial full backup that is required by SQL Server to establish the backup chain, only a single transaction log backup is required to restore a database to the point in time of the transaction log backup. Furthermore, only two transaction log backups are required to restore a database to a point in time between the time of the two transaction log backups.
Used only with BACKUP DATABASE, specifies that the database or file backup should consist only of the portions of the database or file changed since the last full backup. A differential backup usually takes up less space than a full backup. Use this option so that all individual log backups performed since the last full backup do not have to be applied.
When used with BACKUP DATABASE, the COPY_ONLY option creates a full backup that cannot serve as a differential base. The differential bitmap is not updated, and differential backups behave as if the copy-only backup does not exist. Subsequent differential backups use the most recent conventional full backup as their base.
Use FORMAT carefully. Formatting any volume of a media set renders the entire media set unusable. For example, if you initialize a single tape belonging to an existing striped media set, the entire media set is rendered useless.
Under the full recovery model or bulk-logged recovery model, conventional backups also include sequential transaction log backups (or log backups), which are required. Each log backup covers the portion of the transaction log that was active when the backup was created, and it includes all log records not backed up in a previous log backup.
To minimize work-loss exposure, at the cost of administrative overhead, you should schedule frequent log backups. Scheduling differential backups between full backups can reduce restore time by reducing the number of log backups you have to restore after restoring the data.
A copy-only backup is a special-purpose full backup or log backup that is independent of the normal sequence of conventional backups. To create a copy-only backup, specify the COPY_ONLY option in your BACKUP statement. For more information, see Copy-Only Backups.
To avoid filling up the transaction log of a database, routine backups are essential. Under the simple recovery model, log truncation occurs automatically after you back up the database, and under the full recovery model, after you back up the transaction log. However, sometimes the truncation process can be delayed. For information about factors that can delay log truncation, see The Transaction Log.
The BACKUP LOG WITH NO_LOG and WITH TRUNCATE_ONLY options have been discontinued. If you are using the full or bulk-logged recovery model recovery and you must remove the log backup chain from a database, switch to the simple recovery model. For more information, see View or Change the Recovery Model of a Database.
The following example backups up the AdventureWorks2019 sample database, which uses the simple recovery model by default. To support log backups, the AdventureWorks2019 database is modified to use the full recovery model.
This example performs a full database backup of Sales to the Microsoft Azure Blob Storage. The storage Account name is mystorageaccount. The container is called myfirstcontainer. A stored access policy has been created with read, write, delete, and list rights. The SQL Server credential, , was created using a Shared Access Signature that is associated with the Stored Access Policy. For information on SQL Server backup to the Microsoft Azure Blob Storage, see SQL Server Backup and Restore with Microsoft Azure Blob Storage and SQL Server Backup to URL.
This example performs a full backup database of the Sales database to S3-compatible object storage platform. The name of the credential is not required in the statement or to match the exact URL path, but will perform a lookup for the proper credential on the URL provided. For more information, see SQL Server backup and restore with S3-compatible object storage preview.
Backs up a SQL database in Azure SQL Managed Instance. Azure SQL Managed Instance has automatic backups. You can create full database COPY_ONLY backups. Differential, log, and file snapshot backups are not supported.
A database backup created on a managed instance can only be restored on another Azure SQL Managed Instance or to a SQL Server 2022 instance only. This is because SQL Managed Instance has a higher internal database version compared to other versions of SQL Server. For more information, review Restore a SQL Managed Instance database backup to SQL Server 2022.
There are two types of backups in Analytics Platform System (PDW). A full database backup is a backup of an entire Analytics Platform System (PDW) database. A differential database backup only includes changes made since the last full backup. A backup of a user database includes database users, and database roles. A backup of the master database includes logins.
Specifies to perform a differential backup of a user database. If omitted, the default is a full database backup. The name of the differential backup does not need to match the name of the full backup. For keeping track of the differential and its corresponding full backup, consider using the same name with 'full' or 'diff' appended.
A differential backup usually takes less time than a full backup and can be performed more frequently. When multiple differential backups are based on the same full backup, each differential includes all of the changes in the previous differential backup.
Full backups and differential backups are stored in separate directories. Naming conventions are not enforced for specifying that a full backup and differential backup belong together. You can track this through your own naming conventions. Alternatively, you can track this by using the WITH DESCRIPTION option to add a description, and then by using the RESTORE HEADERONLY statement to retrieve the description.
A differential backup is only allowed if the last full backup completed successfully. For example, suppose that on Monday you create a full backup of the Sales database and the backup finishes successfully. Then on Tuesday you create a full backup of the Sales database and it fails. After this failure, you cannot then create a differential backup based on Monday's full backup. You must first create a successful full backup before creating a differential backup.
The following example creates a full backup of the Invoices user database. Analytics Platform System (PDW) will create the Invoices2013 directory and will save the backup files to the \\xxx.xxx.xxx.xxx\backups\yearly\Invoices2013Full directory.
The following example creates a differential backup, which includes all changes made since the last full backup of the Invoices database. Analytics Platform System (PDW) will create the \\xxx.xxx.xxx.xxx\backups\yearly\Invoices2013Diff directory to which it will store the files. The description 'Invoices 2013 differential backup' will be stored with the header information for the backup. 2ff7e9595c
