Experimental Evaluation of Relationships Model Between Documents in MongoDB

Experimental Evaluation of Indexing Between HBase and MongoDB

“…The first type of collection (BasicInformation) contains all attributes of documents, the second type collection (Document) is used as a lookup table with having a relationship to collection (DocumentFrequent) which is used to sort the DocumentId of Document object based on the frequent value of DocumentFrequent object. [12]. Otherwise, on one hand, there is a possibility that the document will increase and have the same name of Word or Title or Author or Year, and the other hand there is a limitation of an embedded document data model in one document, the maximum BSON document size is 16 megabytes [11], so the normalized_1 or normalized_2 is used to give an alternative of the data model.…”

“…There are three data model that can be implemented in MongoDB, where the best data model is embedded [12]. Furthermore, there are two types of indexing that examined in this research which are primary and secondary indexing.…”
