LIST of NOSQL DATABASES [Currently 150]
Your Ultimate Guide to the Non - Relational Universe! [the best selected nosql link Archive in the web] ...never miss a conceptual article again... News Feed covering all changes here! NoSQL DEFINITION: Next Generation Databases mostly addressing some of the points: being non-relational, distributed, open-source and horizontally scalable. The original intention has been modern web-scale databases. The movement began early 2009 and is growing rapidly. Often more characteristics apply such as: schema-free, easy replication support, simple API, eventually consistent / BASE (not ACID), a huge amount of data and more. So the misleading term "nosql" (the community now translates it mostly with "not only sql") should be seen as an alias to something like the definition above. [based on 7 sources, 14 constructive feedback emails (thanks!) and 1 disliking comment . Agree / Disagree? Tell me so! By the way: this is a strong definition and it is out there here since 2009!] LIST OF NOSQL DATABASES [currently 150] Core NoSQL Systems: [Mostly originated out of a Web 2.0 need] Wide Column Store / Column Families Hadoop / HBase API: Java / any writer, Protocol: any write call, Query Method: MapReduce Java / any exec, Replication: HDFS Replication, Written in: Java, Concurrency: ?, Misc: Links: 3 Books [1, 2, 3] Cassandra massively scalable, partitioned row store, masterless architecture, linear scale performance, no single points of failure, read/write support across multiple data centers & cloud availability zones.

We can say mobile de- vices are sibling of personal computers. Mobile device usage patterns are very different as compared to conventional PCs, as the devices are targeted for general users. Mobile devices have some great features, e.g., light weight and efficiency, but it has some drawback like small memory and battery is- sues. Peoples want to use many applications, due to growing the number of purposes, but it challenges to manage the many application in mobile device. Performance of mobile device depends on how to managing our applications and its data. There is a need to measure the performance of various com- monly used applications. Our work start with simple question: does storage affect the performance of mobile device? What kinds of database requires for mobile device? What are the parameter to measure the performance of databases? How to measure the performance of mobile device and its possible tools. -

Testování Embedded Databázových Systémů Benchmarking of Embedded Database Systems
VŠB – Technická univerzita Ostrava Fakulta elektrotechniky a informatiky Katedra informatiky Testování embedded databázových systémů Benchmarking of Embedded Database Systems 2018 David Tabor Rád bych na tomto místě poděkoval vedoucímu bakalářské práce Ing. Petrovi Chovancovi, Ph. D. za odborné vedení a pomoc při realizaci této práce. Abstrakt Cílem této bakalářské práce je vytvořit univerzální testovací rozhraní pro měření výkonu em- bedded databázových systémů v závilosti na zvoleném indexu, čili datové struktuře. Testo- vací rozhraní bude navrženo tak, aby jej bylo možno jednoduchou implementací doplnit o další embedded databázové systémy. Testy budou probíhat nad zvolenými embedded databázovými systémy, zvolenou datovou strukturou a kolekcí dat, která bude generována nebo nahrána z ex- terního souboru a budou uživatele informovat prodstřednictvím webového rozhraní o stavu a průběhu. Historie testů bude ukládána v lokální databázi pro následné vyhodnocení. Klíčová slova: Embedded databázové systémy, RadegastDB, SQLite, MySQL, Firebird SQL, SQL CE, Sekvenční pole (Halda), B-strom, R-strom, Hašovací tabulka Abstract The aim of this bachelor thesis is to create a universal test interface for measuring the perfor- mance of embedded database systems depending on the selected index, i.e. the data structure. The test interface will be designed to be complemented with other embedded database systems by simple implementation. Tests will run over selected embedded database systems, a selected data structure and a data collection that will be generated or loaded from an external file and will inform users via the web interface about status and progress. The history of the tests will be stored in a local database for subsequent evaluation.

The O/R Problem: Mapping Between Relational and Object-Oriented
The O/R Problem: Mapping Between Relational and Object-Oriented Methodologies CIS515 Strategic Planning for Database Systems Ryan Somma StudenID: 9989060874 [email protected] Introduction Relational databases are set of tables defining the columns of the rows they contain, which are also conceptualized as relations defining the attributes of the tuples they store. Relational Database Management Systems (RDBMS) abstract the normalized relational structures underlying the system away from the user, allowing them to focus on the specific data they wish to extract from it. Through queries, they provide users the capability of joining sets in relations into reports, transforming data into information. Through normalization, they eliminate redundancy, ensuring there is only one source for each data element in the system, and improve integrity through relationships based on data keys and validation (Rob and Coronel, 2009). Although there are alternatives to RDBMS‟s, the top five database management systems for 2004 to 2006 were all relational (Olofson, 2007). Object orientation is a “set of design and development principles based on conceptually autonomous computer structures known as objects.” Object-oriented programming (OOP) takes related data elements and functions, known as properties and methods, and encapsulates them into objects that may interact with other objects via messaging or act upon themselves. This strategy reduces complexity in the system, hiding it within objects that are easier to understand as concepts rather than exposing their workings within a morass of procedural code. Additionally, OOP promotes reuse of coding solutions with classes, which are built to model a generalized set of properties and methods that are implemented in object instances, which reuse the class code. -

Embedded Database for Remote Process Management System
Embedded Database for Remote Process Management System {tag} {/tag} IJCA Proceedings on International Conference on Emerging Frontiers in Technology for Rural Area (EFITRA-2012) © 2012 by IJCA Journal EFITRA - Number 4 Year of Publication: 2012 Authors: Kalyani N. Satone Madhuri M . Pal {bibtex}efitra1030.bib{/bibtex} Abstract This paper investigates embedded databases for the MicroBaseJ project. The paper aims at the development of an integrated database and a user interface for a typical 3G mobile phone with Java MIDP2 capability. One of the key objectives is to target a generic solution. A number of commercial sectors could benefit from this solution such as horticulture, building management, pollution/water management, industry etc. Four embedded databases based on J2ME have been investigated. Two of the four have been evaluated and analyzed. The size of processed data is limited to 20000 records when using the wireless toolkit simulator and 11000 records when using a mobile phone. 1 / 3 Embedded Database for Remote Process Management System Refer ences - Mobile and World, "Subscriber statistics end Q1 2007," 2007. - S.
