== History ==
BangDB was developed in 2011 and released its first beta version in 2012 November.<ref name="DB">{{Cite web|url=https://db-engines.com/en/system/Bangdb|title=Bangdb System Properties|website=db-engines.com|access-date=20 August 2020}}</ref> BangDB 0.1 was released with few simple features such as key- value store DB with opaque data, support for [[B-tree|Btree]] + extHash, get, put, delete and simple scan, write-ahead log and buffer pool.<ref>{{Cite web|url=https://nosql-database.org/|title=LIST OF NOSQL DATABASE MANAGEMENT SYSTEMS|last=|first=|date=|website=no-sql database|url-status=live|archive-url=|archive-date=|access-date=20 August 2020}}</ref> When it was first developed, it was mostly used for fast key access especially for a small size data.

In 2014, BangDB 0.9 was released which included features like [[Replication (computing)|replication]], support for multiple table types and index support. Currently BangDB 1.5 is the recent version for BangDB-embedded and server.<ref>{{Cite web|url=https://groups.google.com/forum/#!forum/bangdb|title=Google Groups|website=groups.google.com|access-date=20 August 2020}}</ref>

BangDB is not fully [[Open-source software|open-source]]. It is offered as binaries under [[BSD licenses|BSD]] 3 licence for free which has a limited usage constrain.<ref>{{Cite web|url=https://db-engines.com/en/system/Bangdb|title=Bangdb System Properties|website=db-engines.com|access-date=20 August 2020}}</ref>

BangDB, which is a part of ''IQLECT Software Solutions''<ref>{{Cite web|url=https://quickbooks.intuit.com/in/resources/quickbooks-business-of-the-week/featuring-iqlect/|title=IQLECT: Predictive & real-time data analytics to easily|date=2016-05-16|website=QuickBooks|language=en-US|access-date=20 August 2020}}</ref> was backed by Exfinity ventures in the year 2014.<ref>{{Cite web|url=http://exfinityventures.com/portfolio.html|title=Exfinity ventures startups portfolio|last=|first=|date=2014|website=|url-status=live|archive-url=|archive-date=|access-date=20 August 2020}}</ref><ref>{{Cite news|last=Exfinity Ventures|first=Exfinity Ventures|url=https://www.vccircle.com/hdfc-amc-gets-pe-firm-sovereign-fund-on-board-as-anchor-investors-ahead-of-ipo|title=Ventureast and Exfinity back analytics startup IQLECT in bridge round|date=|work=Vcc Circle|access-date=20 August 2020|url-status=live}}</ref>

== Architecture ==
[[File:BangDb server.png|thumb|BangDB_Server Architecture]]
The architectural objectives while designing the BangDB were:

* The Flexibility - key-value store in various forms
* The performance and scalability
* The robustness and reliability.

=== BangDB - Embedded ===
BangDB Embedded version is part of the BangDB family and a high level architecture consists of three main important components of the Database.<ref>{{Cite web|url=https://ru.bmstu.wiki/BangDB_Embedded|title=BangDB Embedded — Национальная библиотека им. Н. Э. Баумана|website=ru.bmstu.wiki|access-date=20 August 2020}}</ref><ref name="RE">{{Cite web|url=https://bangdb.com/resources/|title=BangDB Resources|website=bangdb.com|access-date=20 August 2020}}</ref>

* The Access Methods or indexes
* The Buffer Pool and management, and
* The [[write-ahead logging|Write Ahead Log]]

'''Access or indexing methods:''' The BangDB access methods are highly concurrent, which means on a machine with more CPUs or Cores, the db will perform better. Btree and hash methods are currently supported in the BangDB as access methods.

'''The Buffer Pool and management:''' The BangDB, when enabled, reads and writes data from the buffer pool. The buffer pool also allows one to control the memory budget on a machine.

'''The Write Ahead Log:''' The BangDB implements [[write-ahead logging|write ahead log]], the ARIES algorithm, for data durability and atomicity. The write-ahead log provides the data recovering capability when required. For example, in the event of process or machine crash etc..., It recovers the data when restarted and brings the DB to the state where it was when it crashed.<ref name="RE"/>

=== BangDB-Server ===
In this flavour, BangDB runs as network service and clients access it over the network. This model is good for sharing data with multiple apps or instances of an app. The typical use case for this flavour is cache on top of the database, a network data store etc.

The architecture of BangDB follows a form of Staged Event-Driven Architecture (SEDA) which suits a highly concurrent network server. The server is stage driven and with a number of stages available as configurable parameter. This makes the server well-conditioned even with increasing loads and connections in a highly stressed scenario.<ref name=":0">{{Cite web|url=http://highscalability.com/blog/2012/11/29/performance-data-for-leveldb-berkley-db-and-bangdb-for-rando.html|title=Performance Data For LevelDB, Berkley DB And BangDB For Random Operations|last=|first=|date=29 November 2012|website=highscalability.com|url-status=live|archive-url=|archive-date=|access-date=20 August 2020}}</ref>

== Main Features ==

=== Compatible with Multi-table types: ===
Compatible with all table types like Normal table, Wide table and primitive table.<ref name="BA">{{Cite web|url=https://bangdb.com/api-server/|title=BangDB 2.0 API|website=bangdb.com|access-date=20 August 2020}}</ref>

=== Multi-indexing: ===
Creates [[index]] on the family or lets database create on auto mode as defined.<ref name="BA"/>

=== Highly Concurrent Operations on B Link - Tree: ===
Manipulation of the tree performed by any thread using a small constant number of page locks anytime. Search procedure does not involve reading any node.<ref name="BA"/>

=== Concurrent Buffer Pools: ===
Separate pools for different types of data with semi-adaptive data flush to ensure performance degrades gracefully in the case of data overflow out of the buffer.<ref name="BB">{{Cite web|url=https://bangdb.com/product/|title=BangDB NoSql|website=bangdb.com|access-date=2020-02-25}}</ref>

=== Sequential Data/log: ===
The write of data/log is always sequential and a Vectored read/write. Across the cluster, the user has more than one option. BangDB can be set as [[ACID]] within the node of the cluster.

=== Memory: ===
Slab allocator is present for most of the memory requirements. Pre-allocated client buffer present for most of the operations which enhances efficient use of memory. It Runs on commodity hardware and with smallest amount of memory committed to it. Users can allocate as much as memory needed or available.

=== Real-time Analytics: ===
Built in abstraction for Real-time data analysis is available. Counting, topk, sliding window are examples of inbuilt analytical abstractions in BangDB for various [[data analytics]].<ref name="BB"/>

=== Concurrency: ===
Most of the data structures are concurrent and capable of handling tens of thousands of concurrent connections.<ref name="BB"/>

=== Complex Event processing: ===
Suitable for [[Complex event processing|Complex Event processing]] and defines queries with no post processing and notifies, alerts while data is in the memory.<ref name="BB"/>

=== Machine Learning: ===
Suitable for training [[machine learning]] models using simple [[Application programming interface|API]] and predicting events or streams and take necessary auto actions. Can be used for Model versioning, release and update process. Suitable for [[A/B testing]] framework, logging and alerting.<ref name="BB"/>

=== R programming: ===
Suitable to run [[R programming|R queries]], building models, generating reports and charts. Integrates with R to provide insights in an ad-hoc manner to understand patterns and to select suitable ML mod-crash recovery model and WAL (Write-ahead log).

=== Robust and Crash-proof: ===
Due to the write-ahead log feature, it frequently check points the log in order to speedup the data recovery process by replaying the log in case of db/machine crash.<ref name="BB"/>

== Differences with other database systems ==
Since BangDB is a NoSQL Database, it is not suitable for any [[RDBMS|relational database management systems (RDBMS)]] and cannot run [[SQL]] based queries. It is also said not to be suitable for heavy business intelligence queries and banking and financial DB structures.

But BangDB is time and storage efficient and has high processing speed for log data analysis, Streaming data performed in a distributed cluster environment.<ref>{{Cite web|url=https://scholarworks.bridgeport.edu/xmlui/bitstream/handle/123456789/1582/189.pdf?sequence=1&isAllowed=y|title=Web Search and Browser Log analysis using BangDB for Decision Support|last=Bridgeport University|first=Scholarworks|date=|website=Brigeport university scholarlinks|url-status=live|archive-url=|archive-date=|access-date=20 August 2020}}</ref>

== Replications ==
The Replication of data is enabled by default in the db. No replication can also be opted by users but in a Network DB scenario, the replication is recommended to be turned ON. The data replication in sync mode allows user to switch between master and standby modes at run time.

Apart from data replication, Log replication can also be opted.<ref name="BB"/>

== Performance ==
BangDB performs well for both read and write in save mode or non-save mode (as a cache). BangDB implements its own buffer pool with semi-adaptive page prefetch and performed well even with billion keys insert when compared with other [[NoSQL]] DBS.

BangDB also implements write ahead log which append only and so it avoids random seeks by optimizing the disk writes.<ref name="BB"/>

== Transaction in BangDB ==
BangDB allows to create multiple user connections and simultaneous operations can be run without any concurrency issues. BangDB is a [[Concurrent data structure|concurrent DB]] engine allowing multiple threads or connections to modify the DB at a time.

For a Single operation, the concurrency is done by locking and for multiple transactions, it is offered through transactions (occ). The transaction can be enabled or disabled by setting appropriate bangdb.config.<ref name="BB"/>

== Supported platform for BangDB server ==

=== Operating Systems: ===
[[Linux]] (Supports [[Ubuntu]], [[Debian]], [[CentOS|CentOS,]] [[Fedora (operating system)|Fedora]], [[Red Hat Enterprise Linux|RedHat]], [[SUSE Linux|SUSE]] etc. with an OS version 2.6 X onwards (32/64) bit)<ref name="BB"/>

=== Language: ===
[[C++]], natively on [[Linux]]

=== Client: ===
[[C++]] and [[Linux]]
