MarkLogic interview: What is DLS library in MarkLogic?

 

Q.1. What is DLS library in MarkLogic?

Ans: 
   DLS library is used for maintain the versions of managed document in the Marklogic server. So that your data will be intact in marklogic while performing any insert/update/delete operation on the document. Marklogic create two copy every time, one is final copy after updating document and second old version copy.   

Example: You want to insert data into DB with '/books.xml'.

You have inserted data with help of dls:document-insert-and-manage() and this function creates two uri: one is  '/books.xml',  and second is '/books_version1.xml'

What is difference between xdmp:estimate and fn:count?

  Ans: Both functions are used for counting the fragments in Marklogic. The xdmp:estimate is fast because it measures through the index and fn:count function also counts the item but also validates in the index and document. But it is not guaranteed that xdmp:estimate & fn:count give the same result. Sometimes xdmp:estimate can give a false result. So fn:count function works slowly as compared to xdmp:estimate. Let's understand in deep, why fn:count & xdmp:estimate results are not the same.  Step-1: Upload below book catalog XML in Marklogic DB. <? xml version="1.0" encoding="UTF-8" ?> < catalog > < book id =" bk101 " > < author > Ralls, Kim </ author > < title > XML Developer's Guide </ title > < genre > Computer </ genre > < price > 44.95 </ price > < publish_date > 2000-10-01 </ publish_date > < description > An in-depth loo...

What is universal index and range index?

  Universal index : The universal index is the indexing process of MarkLogic that Marklogic performs automatically when data is loaded into MarkLogic. By default MarkLogic indexing below universal index: Word Indexing Phrase Indexing Relationship Indexing Value Indexing Word and Phrase Indexing Inverted index: An inverted index inverts the document-word relationship into a word-documents relationship.  Each entry in the inverted index is called a  term list .  Range Index:  Ranges index is also an indexing process in Marklogic but this index is created by the developer based on project requirements. When we need a fast result in the project, we create ranges indexes.   Path range index Element range index Element attribute range index etc...
