== Project Goal==
Develop an adapter to enable NexJ Express model to interact with PostgreSQL database. ===Contributors===* [[User:Gbatumbya|Grace Batumbya]]* [[Minooz/Projects | Minoo Ziaei]]* [[User:AnastasiaS | Anastasia Semionova]] === Supported PostgreSQL Versions===* 8.4+
== Current Status==
* '''Completed''' (October 21, 2011)* Get the last PostgreSQL adapter source code from http://mercurial.nexj.com/express.cgi/core <!--{|class="collapsible collapsed" style="border-style:solid;border-width:thin;border-color:black"

== Project Repository ==
* URL for central repository of the project is: httphttps://liberiabitbucket.proximity.on.ca:81org/gbatumbya/nexjexpress-postgresqladapter
* Steps to work with the repository
:1- Follow the [https://www.projects.openhealthtools.org/sf/docman/do/downloadDocument/projects.oht_aip/docman.root.nexj_studio_express_v7_1_113_0/doc1783/1 instructions to create the NexJ Express workspace from the manual].:2- After creating 'ws' directory, ::open Eclipse and ::click on '''File -> Import -> Mercurial -> Clone Existing Mercurial Repository -> ''':: Enter these this information to clone from repository:::: '''URL''': sshhttps://liberia.proximity.onbitbucket.caorg/mercurialgbatumbya/postgreSQL/core nexjexpress-postgresqladapter:: '''Username''': developer:: '''Clone directory name''': core<!--
:3- The central repository's structure is:
:: Main branch called 'default'
:: New branch or branches with this naming convention: 'wsComitter' e.g. 'wsMinoo'Branches for
:4- After cloning the project, follow these steps to add a new branch with your user name:
:: First make sure the active branch is 'default'. Notice the top of the Package Explorer e.g. ''core[5:b8b2f102343@'''default'''(tip)]''
* '''NOTE!''' To avoid any conflict, do the 'Pull' every day and before any push.
* '''NOTE!''' First just 'Commit' changesets and do not 'Push' them until the end of the day or the time you are confident by latest changes to the code, then 'Push' them all at once and 'Merge' them with the 'default' branch in central repository.
