Abstract: A database management tool may migrate a portion of a constrained database by transferring the portion to a constraint-free database from a first constrained database, then populating a second constrained database using the constraint-free data. The constraint-free data may be transformed prior to populating to update internal database identifiers. In some cases, the transformation may also update the data to a different schema of the target database. The database management tool may also include a load balancer that may monitor the loads on a distributed database and may separate portions of the database to different database instances to more effectively load balance the larger database.

Abstract: Aspects of the subject matter described herein relate to a page flow framework. In aspects, a page flow engine includes logic to navigate between pages. To make its determination of what page is next, the page flow engine uses an indication of the current page and may also use properties associated with the pages. These properties may be filled in as a user enters values on the pages, for example. The page flow engine does not need any additional information to determine the next page besides the current page and the properties. The page flow engine may also store the pages visited in a travel log. This may be used to return previous pages. The page flow engine allows the page flow logic to be removed from the pages and placed in a centralized component. This simplifies creation and maintenance of page flow.

Abstract: Aspects of the subject matter described herein relate to validating properties. In aspects, a property is associated with one or more validators. Each validator includes actions to take to determine whether a feature of the property is valid. Multiple validators may be executed for a single property. A group of validators may be identified by an identifier. In addition, properties may be grouped into collections which may be grouped into other collections and so on. Each collection may also be associated with one or more validators to validate properties within the collections.

Abstract: In aspects, object types are placed in a task repository and controls register with the task repository for notification when a different object type is selected. When a different object type is selected, the task repository is notified of the object type. In response, the task repository determines a list of one or more tasks associated with the selected object type. The task repository then notifies controls that have registered for notification and passes the list of one or more tasks. Using the list and the information included in the tasks, controls may rebuild their portion of a user interface. When a user or process indicates that the actions associated with an element are to be performed, the element calls the task repository and indicates a task to perform. In response, the task repository executes the actions associated with the task.
