AQL: Query Documents and Graphs Easily | ArangoDB 2013
Note: The following article was originally written as an answer in ArangoDB google group. It may help other people to understand the scope of ArangoDB and/or AQL, so we posted it here as well.
AQL, the query language, provides access to the data which is stored inside collections. The collections contain documents, identified by unique keys.
Looking for Beta Tester for the Windows Port
We have a beta version of the Windows port ready for testing. If you are feeling adventurous you can try the brand new beta port of ArangoDB 1.1.1 for windows. Please note, that currently this port only contains the server. The following pieces are still missing:
- no management front-end to start/stop the server or install it as Windows service; the server must be started using a batch script
- arangosh: instead you can use the ArangoDB shell using the admin front-end in the browser
- arangoimp (bulk-importer)
To test the windows port:
- download the installer
- execute the MSI
- this will install the server and the support files und "c:\triagens" (or whatever directory you select)
- execute the batch script "serverExample.bat" in that directory
- wait until you see "Have fun"
- point your browser to "http://localhost:9000"
We have checked the MSI with Avira and tests it under XP, W7, W8. But there will be bugs. Please help us by reporting bugs you encounter using
https://github.com/triAGENS/ArangoDB
If you have improvements or comments, please let us know using the Google group.

Comparing ArangoDB with CouchDB and MongoDB
The folks over at MongoDB have an article on their site on Comparing MongoDB and CouchDB.
They write:
“We are getting a lot of questions “how are mongo db and couch different?” It’s a good question: both are document-oriented databases with schemaless JSON-style object data storage. Both products have their place — we are big believers that databases are specializing and “one size fits all” no longer applies.”
The same applies to ArangoDB, we meet a lot of people especially developers using MongoDB who are interested in ArangoDB and ask us how it is different than other popular nosql databases. In this article we would like to add our answers to the questions asked.

ArangoDB 1.1 Feature Preview: Batch Request API | ArangoDB 2012
Clients normally send individual operations to ArangoDB in individual HTTP requests. This is straightforward and simple, but has the disadvantage that the network overhead can be significant if many small requests are issued in a row.
To mitigate this problem, ArangoDB 1.1 offers a batch request API that clients can use to send multiple operations in one batch to ArangoDB. This method is especially useful when the client has to send many HTTP requests with a small body/payload and the individual request results do not depend on each other.

ArangoDB 2012: Gain Factor of 5 with Batch Updates
ArangoDB 1.1 will come with a new API for batch requests. This batch request API allows clients to send multiple requests to the ArangoDB server inside one multipart HTTP request. The server will then decompose the multipart request into the individual parts and process them as if they were sent individually. The communication layer can sustain up-to 800.000 requests/second – but absolute numbers strongly depend on the number of cores, the type of the requests, network connections and other factors. More important are the relative numbers: Depending on your use-case you can reduce insert/update times by 80%.
