MySQL officially, but also called “My Sequel” is the world’s second most widely used open-source relational database management system (RDBMS). The MySQL development project has made its source code available under the terms of the GNU General Public License, as well as under a variety of proprietary agreements. MySQL is a popular choice of database for use in web applications, and is a central component of the widely used LAMP open source web application software stack. LAMP is an acronym for “Linux, Apache, MySQL, Perl/PHP/Python.” Free-software-open source projects that require a full-featured database management system often use MySQL.
PostgreSQL, often simply Postgres, is an open source object-relational database management system (ORDBMS) with an emphasis on extensibility and standards compliance. It is released under the PostgreSQL License, a free/open source software license, similar to the MIT License. It implements the majority of the SQL:2011 standard, is ACID-compliant, is fully transactional (including all DDL statements), has extensible updateable views, data types, operators, index methods, functions, aggregates, procedural languages, and has a large number of extensions written by third parties. PostgreSQL is available for many platforms including Linux, FreeBSD, Solaris, Microsoft Windows and Mac OS X.
SQLite is a relational database management system contained in a small C programming library. In contrast to other database management systems, SQLite is not a separate process that is accessed from the client application, but an integral part of it. SQLite is ACID-compliant and implements most of the SQL standard, using a dynamically and weakly typed SQL syntax that does not guarantee the domain integrity. SQLite is a popular choice as embedded database for local/client storage in application software such as web browsers. It is arguably the most widely deployed database engine, as it is used today by several widespread browsers, operating systems, and embedded systems, among others. SQLite has many bindings to programming languages.
Apache Hadoop is an open-source software framework for storage and large scale processing of data-sets on clusters of commodity hardware. Hadoop is an Apache top-level project being built and used by a global community of contributors and users. It is licensed under the Apache License 2.0. All the modules in Hadoop are designed with a fundamental assumption that hardware failures (of individual machines or racks of machines) are common and thus should be automatically handled in software by the framework. Apache Hadoop’s MapReduce and HDFS components originally derived respectively from Google’s MapReduce and Google File System (GFS) papers.
HBase is an open source, distributed database written in Java language. It is developed as part of Apache Hadoop project and runs on top of Hadoop Distributed File System, facilitating BigTable like capabilities for Hadoop. In a way, hBase gives a fault-tolerant way of storing large amount of sparse data.
As hBase is part of big data processing platform that is Apache Hadoop, it possess some key outstanding features. It provides access to single rows rapidly from a million row table. It also has a flexible data model to work and faster scans are possible across all tables. hBase is a column-oriented database management system.
Some of its extraordinary features are in-memory operation and that the tables can also be accessed via Java API.
Apache hBase is a capable Database management system and Bid Data Service facilitator that Laitkor is well capable of serving its client with.
