{"title":"Comparison of Relational Database with Document-Oriented Database (MongoDB) for Big Data Applications","authors":"Satyadhyan Chickerur, Anoop Goudar, Ankita Kinnerkar","doi":"10.1109/ASEA.2015.19","DOIUrl":"https://doi.org/10.1109/ASEA.2015.19","url":null,"abstract":"Database can accommodate a very large number of users on an on-demand basis. The main limitations with conventional relational database management systems (RDBMS) are that they are hard to scale with Data warehousing, Grid, Web 2.0 and Cloud applications, have non-linear query execution time, have unstable query plans and have static schema. Even though RDBMS's have provided database users with the best mix of simplicity, robustness, flexibility, performance, scalability and compatibility but they are not able to satisfy the present day users and applications for the reasons mentioned above. The next generation NonSQL (NoSQL) databases are mostly non-relational, distributed and horizontally scalable and are able to satisfy most of the needs of the present day applications. The main characteristics of these databases are schema-free, no join, non-relational, easy replication support, simple API and eventually consistent. The aim of this paper is to illustrate how a problem being solved using MySQL will perform when MongoDB is used on a Big data dataset. The results are encouraging and clearly showcase the comparisons made. Queries are executed on a big data airlines database using both MongoDB and MySQL. Select, update, delete and insert queries are executed and performance is evaluated.","PeriodicalId":259240,"journal":{"name":"2015 8th International Conference on Advanced Software Engineering & Its Applications (ASEA)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131659874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Position of target is to estimate for desired direction of arrival among incident signals with receiver system. We use an adaptive array antenna. In order to obtain an optimum weight value, we study direction of arrival estimation algorithm with cost MUSIC algorithm. Through simulation, we show that compare cost MUSIC algorithm with general algorithm. In this paper, Direction of arrival estimation improved more proposed algorithm than general algorithm.","PeriodicalId":259240,"journal":{"name":"2015 8th International Conference on Advanced Software Engineering & Its Applications (ASEA)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132399616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our concern lies on how to best engage user adaptation on a system with high demands in terms of user interest. We have come up with a combined decision making process for its design. In earlier stages we employ the informal QOC ensuring that high level decisions are sound and explicit throughout design and later on we use formal SAW, which is applied on every high-level decision to further weigh the user adaptation attributes that are adopted. This two-sided attack approach ensures design integrity and a high degree of flexibility to our system.","PeriodicalId":259240,"journal":{"name":"2015 8th International Conference on Advanced Software Engineering & Its Applications (ASEA)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123868843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
