SQLite vs. Cassandra vs. CouchDB

Used for testing.

Used on our client(s)

Gestor de base de datos para el almacenamiento de datos en aplicaciones móviles.

For smaller internal tools we build that requires easy local storage.

There's really no call for something heavier for this site. SQLite is simple, easy to use and quite reliable given its age.

DB backend, when required

Local DB on iOS devices

For V.1.0 all data is stored using phonegap SqliteStorage plugin,

We support SQLite databases so that developers can interact with their data.

Storage of data for both mobile apps and native apps

All the dynamic data (i.e.: jobs) is stored in a simple SQLite database.

Все динамические данные (вакансии) хранятся в простой SQLite БД.

Database for mobile development

Local Django unit testing

We build queries in PHP with DSQL that work with SQLite. We also have SQLite data controller, so that you can build SQLite-based models.

Datasource for CoreData

Used SQLite with Ghost for Blogging service, both are free.

SQLite is used in the Android application, to store data on the mobile

basic

Only on local projects, nothing in production :-)

Inline DB on clients and apps.

RDBTools is a self-hosted application, and it is important that the installation process is simple. With SQLite, we create a new database file for every analysis. Once the analysis is done, the SQLite file can be thrown away easily.

Mobile app local databases.

For support reasons not relay used

Stitch is a wrapper around a Cassandra database. It has a web application that provides read-access to the counts through an HTTP API. The counts are written to Cassandra in two distinct ways, and it's possible to use either or both of them:

• Real-time: For real-time updates, Stitch has a processor application that handles a stream of events coming from a broker and increments the appropriate counts in Cassandra.

• Batch: The batch part is a MapReduce job running on Hadoop that reads event logs, calculates the overall totals, and bulk loads this into Cassandra.

Implements the App Engine Datastore API.

Stores massive data, distributed among many different clusters.

Cassandra is our data management workhorse. It handles all our key-value services, supports time-series data storage and retrieval, securely stores all our audit trails, and backs our Datomic database.

Logs storage and aggregation

We are using Cassandra in a few of our apps. One of them is as a count service application to track the number of shares, clicks.. etc

Storage and management of Virtual Services

While we experimented with Cassandra in the past, we are no longer using it. It is, however, open for consideration in future projects.

Hot storage system

Datastax interview

某プロプライエタリなWebアプリを動かすのに必要だった(インストールと構築のみ)

Used Cassandra's CQL for database query.

Big data analytics.

As a part of big data machine learning stack (SMACK)

By being built on, of, in and around CouchDB, Smileupps offers to its customers secure and reliable CouchDB hosting and a CouchDB-based app store to build and sell serious business-enabled web applications

Storage for unstructured, linked and timeseries data.

We use CouchDB in an internal analysis tool for usage data.

json store + geo + _changes

Document (JSON) DB.

• - queries must be pre-defined as views (not as flexible as query formulation on the fly)
• - community and ecosystem not as large as mongodb
• + PouchDB is an excellent JS library to interact with CouchDB or even work in offline-then-sync moce
