CouchDB Documents Module

It is implemented in such a way that it is configurable whether to store the documents only in the disk or CouchDB. The CouchDB has got a good replication feature which will make it easy to have a copy of documents in another system. Its also a good feature that CouchDB database is in consistent stage at every time. So a backup of CouchDB database can be taken at anytime by simply copying the database(CouchDB_root/var/lib/couchdb). We think this feature will be useful when the documents total size grows into GBs.

Even though CouchDB is not officially supported in Windows an unofficial version is available here:

1) http://wiki.apache.org/couchdb/Installing_on_Windows 2) https://github.com/downloads/dch/couchdb/setup-couchdb-1.1.1_js185_otp_R14B03+fix-win32-crypto.exe

Linux version is available here:

1) http://couchdb.apache.org/downloads.html

We have implemented this feature in Documents upload/download screen in Patient Demographics. This feature also can be used for storing the following files:

1) Generated X12 file 2) Generated PDF file 3) ERA file

We will implement it after getting the feedback from the community.

Configuring:

1) Install the Apache CouchDB. 2) If installation is success, normally it will be available on port number 5984. 3) It can be reached through the browser (http://localhost:5984). 4) Basic administration utility will be available in http://localhost:5984/_utils. 5) Initially it is running without username and password with all privileges. This can be reset by going to CouchDB\etc\couchdb\local.ini. In the lower side uncomment the

admin = mysecretpassword . Put the desired password. On restarting the couchDB, this will take effect and also the password set will be hashed in the local.ini.

6) Enable CouchDB from Administration->Globals->Documents->Document Storage Method.
