Types of result caches in Microstrategy

Types of result caches Microstrategy

The following types of result caches are created by Intelligence Server:

•

Matching caches

•

History caches

•

Matching-History caches

•

XML caches

All document caches are Matching caches; documents do not generate History caches or XML caches. Intelligent Cube reports do not create Matching caches.

Matching caches

Matching caches are the results of reports and documents that are retained for later use by the same requests later on. In general, Matching caches are the type of result caches that are used most often by Intelligence Server.

When result caching is enabled, Intelligence Server determines for each request whether it can be served by an already existing Matching cache. If there is no match, it then runs the report or document on the database and creates a new Matching cache that can be reused if the same request is submitted again. This caching process is managed by the system administrator and is transparent to general users who simply benefit from faster response times.

History caches

History caches are report results saved for future reference in the History List by a specific user. When a report is executed, an option is available to the user to send the report to the History List. Selecting this option creates a History cache to hold the results of that report and a message in the user’s History List pointing to that History cache. The user can later reuse that report result set by accessing the corresponding message in the History List. It is possible for multiple History List messages, created by different users, to refer to the same History cache.

The main difference between Matching and History caches is that a Matching cache holds the results of a report or document and is accessed during execution; a History cache holds the data for a History List message and is accessed only when that History List message is retrieved.

For more information about History Lists, see Saving report results: History List.

Matching-History caches

A Matching-History cache is a Matching cache that is referenced by at least one History List message. It is a single cache composed of a Matching cache and a History cache. Properties associated with the Matching caches and History caches discussed above correspond to the two parts of the Matching-History caches.

XML caches

An XML cache is a report cache in XML format that is used for personalized drill paths. It is created when a report is executed from MicroStrategy Web, and is available for reuse in Web. It is possible for an XML cache to be created at the same time as its corresponding Matching cache. XML caches are automatically removed when the associated report or History cache is removed.

To disable XML caching, select the Enable Web personalized drill paths option in the Project definition: Drilling category in the Project Configuration Editor. Note that this may adversely affect Web performance.

Settings for Outer Join between metrics in MicroStrategy

Settings for Outer Join between metrics in MicroStrategy MicroStrategy adopts multi-pass logic to determine the execution plan for a report. This means that every metric is evaluated in separate SQL passes. Outer Joins come into play when MicroStrategy Engine merges the results from all SQL passes into one report. For a multi-pass report, different Outer Join behaviors can give the user completely different results. In addition, report metrics can be of different types which can, in some cases, influence the result of the outer join. In MicroStrategy, there are two settings that users can access to control Outer Join behavior : Formula Join Type and Metric Join Type . Metric Join Type: VLDB Setting at Database Instance Level Report and Template Levels Report Editor > Data > Report Data Options Metric Level Metric editor > Tools > Metric Join Type Control Join between Metrics Formula Join Type: Only at Compound/Split...

Types of prompts in Microstrategy

Types of prompts in Microstrategy The different types of prompts allow you to create a prompt for nearly every part of a report. Prompts can be used in many objects including reports, filters, metrics, and custom groups, but all prompts require user interaction when the report is executed. The correct prompt type to create depends on what report objects you want users to be able to base a filter on to filter data, as described in the list below. Filter definition prompts allow users to determine how the report's data is filtered, based on one of the following objects: Attributes in a hierarchy : Users can select prompt answers from one or more attribute elements from one or more attributes. The attribute elements that they select are used to filter data displayed on the report. This prompt lets you give users the largest number of attribute elements to choose from when they answer the prompt to define their filtering criteria. For example, on a repor...

Types of filters in Microstrategy

Types of filters in Microstrategy Below are the types of filters: 1. Attribute qualification filter These types of qualifications restrict data related to attributes on the report. a) Attribute form qualification Filters data related to a business attribute’s form(s), such as ID or description. • For example, the attribute Customer has the forms ID, First Name, Last Name, Address, and Birth Date. An attribute form qualification might filter on the form Last Name, the operator Begins With, and the letter H. The results show a list of customers whose last names start with the letter H. b) Attribute element list qualification Filters data related to a business attribute’s elements, such as New York, Washington, and San Francisco, which are elements of the attribute City. • For example, the attribute Customer has the elements John Smith, Jane Doe, William Hill, and so on. An attribute element list qualification can filter data to display only those customer...

Allow a Visualization to Update the Data in Another Visualization in Dossier

Allow a Visualization to Update the Data in Another Visualization After adding multiple visualizations to a dossier, you can select values in one visualization (that is, the source) to automatically update data in another visualization (that is, the target). This is done by creating a filter on a visualization that targets other visualizations. To Add a Target Visualization to Your Dossier: Open the dossier with the visualization. Click Insert Visualization . A blank visualization appears in the dossier. From the Visualizations panel, select Grid . Drag an attribute from the Datasets panel to the Rows area of the Editor panel to add attributes to the rows. Drag an attribute from the Datasets panel to the Columns area of the Editor panel to add attributes to the columns. Drag a metric from the Datasets panel to the Metrics area of the Editor panel, to add a metric to the grid. The Metric Names attribute automatically appears i...
