I have been working with relational databases for sometime, but it only recently occurred to me that there must be other types of databases that are non-relational. What are some examples of non-relational databases, and where/how are they used in the real world? Why would you choose to use a non-relational database over relational dat...
Hi All, I have found relational database options, but I want to see if there are any faster non-relational databases that could do better. I am storing up to 32 GB of these records which contain 3 ints, a byte[8] array (or binary(8)), and a double. I will RARELY RARELY query the database, but I need to make sure that if I do read fr...
I'm learning traditional Relational Databases (with PostgreSQL) and doing some research I've come across some new types of databases. CouchDB, Drizzle, and Scalaris to name a few, what is going to be the next database technologies to deal with? ...
Why should I use document based database like CouchDB instead of using relational database. Are there any typical kinds of applications or domains where the document based database is more suitable than the relational database? ...
I want to experiment/play around with non-relational databases, it'd be best if the solution was: portable, meaning it doesn't require an installation. ideally just copy-pasting the directory to someplace would make it work. I don't mind if it requires editing some configuration files or running a configuration tool for first time usag...
We a have a GDBM key-value database as the backend to a load-balanced web-facing application that is in implemented in C++. The data served by the application has grown very large, so our admins have moved the GDBM files from "local" storage (on the webservers, or very close by) to a large, shared, remote, NFS-mounted filesystem. This ...
The Perl DBI module lets me connect to many different types of SQL database transparently. Is there an equivalent Perl module for non-relational key-value pair databases? For example, an interface that might let me start developing with a BerkeleyDB (or even just a Perl hash?) but switch to something like memcachedb or CouchDB or even ...
I have a web application running over a MySQL database (in development). I'm considering to migrate my application to Google App Engine, and would like to better understand how my simple relational database model can be transformed to the non-relational approach. I'm a long time relational database person, and I have no experience with ...
BerkeleyDB is the database equivalent of a Ruby hashtable or a Python dictionary except that you can store multiple values for a single key. My question is: If you wanted to store a complex datatype in a storage structure like this, how could you go about it? In a normal relational table, if you want to represent a Person, you create ...
Hey guys, please recommend some tools you have used succesfully on DW, DataMart, BI an non-relational modeling. Example for automatic creation of snow-flake Schemas, dimensions and facts tables. Wich tools makes you sense familiarity with the diagrams and surrogates keys and it will have the option for export or connect to SQL Server 200...
Hi. I am in the early stages of developing a sports statistics website (ultimate frisbee) and would like to know your opinions if Google App Engine is right for me. I am writing it in Python using Django and have been comfortable with standard RDBMS for years but this site is a long term project and I am expecting very large amounts of ...
Let's say I'm writing a log analysis application. The main domain object would be a LogEntry. In addition. users of the application define a LogTopic which describes what log entries they are interested in. As the application receives log entries it adds them to couchDB, and also checks them against all the LogTopics in the system to see...
I've been reading up on a lot of posts about non-relational databases, the whole NOSQL movement, and there's a lot of fresh new activity around it. It seems like a very interesting approach to building highly scalable web applications but unfortunately (but also a good thing at this nascent stage) there isn't quite a clear leader/standar...
I want to start playing with non-relational database, but want something that is popularly used with Rails. I'm considering the ones in the article and leaning towards Voldemort or CouchDB: http://www.ithighlight.com/2009/07/list-of-companies-powered-by-non-relational-database/ Any recommendations? ...
Anyone have any recommendations for a non-relational/partially-relational DB with a .NET API? ...
Hi there, I am looking into the best ways for storing surveys to a database with Rails. I have checked out this great Smerf Survey Plugin for Rails which stores surveys into a Relational Database with the following tables: smerf_forms: name, code smerf_forms_users: user_id, smerf_form_id, responses (as text) smerf_responses: smerf_f...
Good day, I have been using Rails/Mysql for the past while but I have been hearing about Cassandra, MongoDB, CouchDB and other document-store DB/Non-relational databases. I'm planning to explore them later as they might be better alternative for scalability. I'm planning to start an application soon. Will it make a different with Rail...
Im looking for a way to map an ActiveResource to SimpleDB I want to avoid plugins/gems as all I have used are outdated/buggy/not mantained It doesnt seem hard, I wonder if any of you have succesfully implemented a rails app with simpleDB as an Active Resource. How did you do it? Thanks. ...
Please, can you give examples of real-life implementations using SimpleDB as the main persistent storage? ...
The benefits of a non-relational database (such as a key-value pair storage) are evident when used in large scale datasets (google, facebook, linkedin). How do you think small to medium sized applications can benefit from using non-relational databases? ...
