    <p>I am playing around with <a href="http://couchdb.apache.org/" rel="nofollow noreferrer">CouchDB</a> to test if it is "possible" [1] to store scientific data (simulated and experimental raw data + metadata). A big pro is the schema-less approach of CouchDB: we have to be very flexible with the metadata, as the set of parameters changes very often.</p> <p>Up to now I have some code to feed raw data, plots (both as attachments), and hierarchical metadata (as JSON) into CouchDB documents, and have written some prototype Javascript for filtering and showing. But the filtering is done on the client side (a.k.a. browser): The map function simply returns everything.</p> <p>How could I change the (or push a second) map function of a specific _design-document with simple browser-JS?</p> <p>I do not think that a temporary view would yield any performance gain...</p> <p>Thanks for your time and answers.</p> <p>[1]: of course it is possible, but is it also useful? feasible? reasonable?</p> <p><strong>[added]</strong></p> <p>Ah, the jquery.couch.js (version 0.9.0) provides a saveDoc() function, which could update the _design document with the new map function.</p> <p>But I also tried out the query function, which uses a temporary view. Okay, "do not use this in the real product, only during development"... But scientific research <em>is</em> steady development, right?</p> <p>Temporary views are getting cached, as I noticed, and it works well for ~1000 documents per DB. A second plus: all users (think of 1 to 3, so a big user management is quit of an overkill) can work with their own temporary view.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
