The paper presents an original algorithm for automatic mapping of relational databases to MongoDB NoSQL databases. The algorithm uses the metadata stored in the relational system tables. It takes into consideration the concepts from Entity-Relationship (ER) model: entity type represented by a relation in the Relational Model (RM), 1:1 and 1:M relationship type represented with Foreign Keys (FK)...

this article presents a novel method and development paradigm that proposes a general template for an enterprise information structure and allows for the automatic generation and modification of enterprise workflows. this dynamically integrated workflow development approach utilises a conceptual ontology of domain processes and tasks, enterprise charts, and enterprise entities. it also suggests...

To benchmark and rate a data store, one might be required to repeatedly load the same benchmark database onto the data store. This may constitute a significant portion of the benchmarking process. This paper focuses on the BG benchmark (www.bgbenchmark.org) and presents three techniques to expedite loading of its database. These include generating the disk image of the database once and reusing...

NoSQL document databases emerged as an alternative to relational for managing large volumes of data. ensure big data storage and good query performance are essential when the scheme does not fit into databases. They store their in form documents can handle unstructured, semi-structured, structured This work evaluates top three open-source databases: Couchbase, CouchDB, MongoDB with Yahoo! Cloud...

Supporting large amounts of spatial data is a significant characteristic of modern databases. However, unlike some mature relational databases, such as Oracle and PostgreSQL, most of current burgeoning NoSQL databases are not well designed for storing geospatial data, which is becoming increasingly important in various fields. In this paper, we propose a novel method to provide R-tree index, as...

In this paper we present an overview of the V2 temporal document database system, which supports storage, retrieval, and querying of temporal documents.

Data transformation is the core process in migrating database from relational to NoSQL such as column-oriented database. However, there no standard guideline for data A number of schema techniques have been proposed improve and resulted better query processing time when compared time. these approaches produced redundant tables that turn consume large unnecessary storage size produce high due ge...

Database is one of the most important parts in running an application. Databases can be used to store data. However, application, selection appropriate database needs considered, so that resulting information accordance with user needs. In developing applications, more people use RDBMS design which has a very structured nature, but technological developments have introduced NoSQL as development...

The World Wide Web infrastructure together with its more than 2 billion users enables to store information at a rate that has never been achieved before. This is mainly due to the will of storing almost all end-user interactions performed on some web applications. In order to reply to scalability and availability constraints, many web companies involved in this process recently started to desig...
