Sun, 03 Oct 2021 04:06:35 +0000

Correct answer is -i) True

MarkLogic fuses together database internals, search-style indexing, and application server behaviors into a unified system. It uses XML and JSON documents as its data model, and stores the documents within a transactional repository. It indexes the words and values from each of the loaded documents, as well as the document structure.

Answered: ______ data model is used in MarkLogic.

Sun, 03 Oct 2021 04:05:57 +0000

Correct answer is -iv) Document Data Model

Document Data Model data model is used in MarkLogic.The basic unit of organization in MarkLogic is a document. These can be encoded in JSON or XML.MarkLogic stores Documents as compressed trees, based on the well-known XPath Data Model. This model is sufficiently featured to represent all sorts of documents, including plain-text and JSON.The advantage of storing documents in XML format is that you can query the tree structure, using XPath expressions such as /doc/title. And with MarkLogic, you can perform searches that are aware of and can be qualified by this tree structure.

Answered: What is the port for the Configuration Manager?

Sun, 03 Oct 2021 04:05:21 +0000

Correct answer is -iii) 8002

8002 is the port for the Configuration Manager. To access the Configuration Manager page, users must have the role manage-user and use port 8002. The role does not grant any privileges to modify configuration settings. Users with the manage-user role may:

Access the Configuration Manager pages to view resources and settings.
Export configurations to an ZIP file (with the exception of modules databases).>
Import previously saved configurations into the Configuration Manager to view or compare them.

The manage-user role does not grant privileges to edit configuration settings, apply configuration changes from an imported configuration, or to export modules databases. To export the content of modules databases, you must have the manage-admin role. However, you won't be able to see modules that you don't have permissions to access. To install (Apply importeiv) packages, you must to have the admin privilege.

Answered: What is the port for the Admin interface?

Sun, 03 Oct 2021 04:04:25 +0000

Correct answer is -iv) 8001

8001 is the port for the Admin interface. Check for other processes on port 8001: sudo netstat -nlp | grep 800 is a good start. If there is anything else on port 8001 you will have to shut it down, at least while configuring MarkLogic for the first time. After that you might be able to shift the admin server to a different port, but that's not trivial.

Answered: What is needed to be able to store data in a database?

Sun, 03 Oct 2021 04:03:55 +0000

Correct answer is -i) Forests

Forests is needed to be able to store data in a database.A database consists of one or more forests. A forest is a collection of documents that is implemented as a physical directory on disk. Each forest holds a set of documents and all of their indexes.

Answered: Which of these provide a way to load data into a MarkLogic database?

Sun, 03 Oct 2021 04:03:23 +0000

Correct answer is -iv) All the options

Xquery and Javascript functions,REST API, Node.Js API, Java API and MarkLogic Content Pump provides a way to load data into a MarkLogic database. MarkLogic Server provides many ways to load content into a database including built-in XQuery functions, the REST Client API, and the command-line tool, MarkLogic Content Pump (mlcp). Choosing the appropriate method for a specific use case depends on many factors, including the characteristics of your content, the source of the content, the frequency of loading, and whether the content needs to be repaired or modified during loading. In addition, environmental and operational factors such as workflow integration, development resources, performance considerations, and developer expertise often need to be considered in choosing the best tools and mechanisms.

Answered: Indexes are for improving the performance of queries, and, for some MarkLogic features, are required.

Sun, 03 Oct 2021 04:02:34 +0000

Correct answer is -i) True

yes, it is true. Indexes are for improving the performance of queries, and, for some MarkLogic features, are required.

The increased list cache will improve query performance. Use some of the reclaimed memory from the expanded tree cache to increase the list cache.MarkLogic enables some default full-text search indexes and any inserted content populates these indexes. There are situations where these indexes may need to be changed, including:

to enable additional search functionality in a MarkLogic application
to increase accuracy of unfiltered searches
to create additional facets or lexicon-based functions
to recognize enhancements or bug fixes between MarkLogic versions
to remove unused indexes to reclaim disk space

Answered: Forests are created on hosts and are attached to databases to appear as a contiguous set of content for query purposes.

Sun, 03 Oct 2021 04:01:53 +0000

Correct answer is -i) True

yes, it is true. Forests are created on hosts and are attached to databases to appear as a contiguous set of content for query purposes.A forest is a collection of XML, JSON, text, or binary documents. Forests are created on hosts and attached to databases to appear as a contiguous set of content for query purposes. A forest can only be attached to one database at a time. You cannot load data into a forest that is not attached to a database.

A forest contains in-memory and on-disk structures called stands. Each stand is composed of XML, JSON, binary, and/or text fragments, plus index information associated with the fragments.

When fragmentation rules are in place, XML documents may span multiple stands. MarkLogic Server periodically merges multiple stands into a single stand to optimize performance. See Understanding and Controlling Database Merges for details on merges.

Answered: Integration with Marklogic is ____ times faster than a traditional database.

Sun, 03 Oct 2021 04:00:49 +0000

Correct answer is -i) Four

Integration with Marklogic is four times faster than a traditional database.Integrating data from silos is rarely as simple as migrating all the data into MarkLogic and then retiring the old systems. Those systems must typically be kept online to serve various purposes, so integrating them means bringing a steady stream of data from those systems into MarkLogic. Fortunately, getting data into MarkLogic is easy, and many existing technologies address enterprise application integration (EAI) patterns. Attend this presentation to see how Apache Camel, a popular EAI tool, and MarkLogic complement each other to address your EAI challenges.

Answered: Reindexing a database can be stopped by resetting the timestamp to____

Sun, 03 Oct 2021 03:59:57 +0000

Correct answer is -ii) 0

Reindexing a database can be stopped by resetting the timestamp to 0.You can disable reindexing, but it's worthwhile thinking about what problem you're trying to solve by doing that.

Reindexing only happens if you change index settings, and presumably if you change index settings, you'll want the new settings to take effect. If you frequently change index settings and want to control how much resource goes into reindexing, you can also throttle.Specifies the timestamp of fragments to force a reindex/refragment operation. Click the get current timestamp button to enter the current system timestamp. When you set this parameter to a timestamp and reindex enable is set to true, it causes a reindex and refragment operation on all fragments in the database that have a timestamp equal to or less than the specified timestamp.

Note that if you restore a database that has a timestamp set, if there are fragments in the restored content that are older than the specified content, they will start to reindex as soon as they are restored.

Answered: In the Admin interface, how can you create a database?

Sun, 03 Oct 2021 03:58:51 +0000

Correct answer is -iii) Configure-Databases-Create tab

In the Admin interface,Configure-Databases-Create tab you create a database

Click the Databases icon in the left tree menu.
Click the Create tab at the top right. The Create Database page displays:

Answered: _______ are the secret sauce to MarkLogics ability that provide real-time queries on extremely huge databases.

Sun, 03 Oct 2021 03:53:22 +0000

Correct answer is -i) Indexes

Indexes are the secret sauce to MarkLogics ability that provide real-time queries on extremely huge databases.With the technological advances and the ever-changing market today, companies need a foundation that is adaptable and fast. There is a need for organizations to use data in an integrated manner in real time, and databases need to allow seamless use of data out of the box.

In traditional, relational databases, data resides in rows and columns with very little flexibility and context. To add to the problem data today resides in different systems and in different formats. To fulfill a specific data need, organizations need to create a new unified view of the data by creating schemas and using extract, transform, load (ETL) which can be difficult because relational databases are rigid. Not only does this create a new data silo, but makes the data out of date as soon as the integration starts because business needs are always changing.

Answered: ______ indexing match by the exact latitude longitude that are used to draw city boundaries.

Sun, 03 Oct 2021 03:46:01 +0000

Correct answer is -i) Geospatial Index

Geospatial Index indexing match by the exact latitude longitude that are used to draw city boundaries.

To calculate geometry over an Earth-like sphere, store your location data as GeoJSON objects.

To specify GeoJSON data, use an embedded document with:

a field named type that specifies the GeoJSON object type and

a field named coordinates that specifies the object's coordinates.

If specifying latitude and longitude coordinates, list the longitude first and then latitude:

Valid longitude values are between -180 and 180, both inclusive.

Valid latitude values are between -90 and 90, both inclusive.

<field>: { type: <GeoJSON type> , coordinates: <coordinates> }

For example, to specify a GeoJSON Point:

location: {

type: "Point",

coordinates: [-73.856077, 40.848447]

}

For a list of the GeoJSON objects supported in MongoDB as well as examples, see GeoJSON objects.

MongoDB geospatial queries on GeoJSON objects calculate on a sphere; MongoDB uses the WGS84 reference system for geospatial queries on GeoJSON objects.

Answered: Which of the following are the auxillary databases?

Sun, 03 Oct 2021 03:44:03 +0000

Correct answer is -e) All the options

Module Database, Security Database, Schema Database and Triggers Database are the auxillary databases.While configuring a scheduled backup, one can also select to backup the associated auxiliary databases like security, schemas, triggers. Generally, all the content databases share these auxiliary databases so issue may arise when more than one scheduled backup tries to backup the same auxiliary database. When two backups try to backup the same auxiliary database, the backup will fail throwing XDMP-FORESTOPIN error. Generally this error comes when the system attempts to start one forest operation (backup, restore, remove, clear, etc.) while another, exclusive operation is already in progress. For example, starting a new backup while a previous backup is still in progress.
