- W2277419414 abstract "Cloud architectures are most commonly used in cases when large scale data processing isrequired. Building applications for cloud architectures requires a lot of engineeringexperience, especially in cases of data persistence. Persistence in cloud architectures is solvedusing NoSQL database models. In this paper we are working with column oriented NoSQLdatabase model. Main research goal of this paper is building of new persistence framework for column oriented NoSQL databases. H2O (HBase to Object) framework is created toresolve problem of mapping objects into rows in column oriented database and to provideeffective mechanisms for data retrieval. Main focus of this framework is to supportpersistence of domain models presented by standard UML language. Current implementationsupports storing content into HBase NoSQL database. Core engine of H2O framework isbuilt on top of XPath standard. All mappings between domain model attributes and columnsin row are represented using XPaths. These paths are used to transform object into row andvice versa. H2O framework contains component for integration with Hadoop map reduceprocessing library to simplify writing of Hadoop map reduce parallel programs. We took twohardware platforms of same price. First platform have HBase 0.90.1 and H2O installed andother have installed Oracle 11g and Hibernate framework. We are comparing performance ofthese two platforms from aspects of retrieval and persistence of objects. Result of ourcomparison is that NoSQL model is better from aspects of retrieval by primary key but showslower performances in save operations.Keywords: NoSQL, persistence, distributed, HBase, Hadoop, mapping, framework, UML,map-reduce" @default.
