Avg Bid (USD)
Project Budget (USD)
$30 - $250

Project Description:
We are looking for a small [url removed, login to view] control and 2 classes for the DB interaction for storing, updating simple key value pairs in a table. Very little oracle knowledge is required, only to write a few straightforward queries

The table roughly speaking has the columns
ID, Project,Namespace,Category,SubCategory,dicKey,DicValue
the Id is gnerated from a sequence in Oracle i.e. equivalent to an autoincrement
Project,Namespace,Category,SubCategory are hierarchical so subcategory is UNDER Category which is under Namespace which is under project
For the combination Project,Namespace,Category,SubCategory : we then have a dickey,dicvalue pairs
so by select all matching Project,Namespace,Category,SubCategory I obtain a set of key /values

I will provide the schema for the table.

We also need a .net control which roughly speaking allow us to add value into the table. The detailed description is attached.

Please note an important point for the Add new Button. The Add new does not save to the database. This must be done on the client side (i.e. a small piece of javascript to add a row to the table. This is for speed reasons, it is important NOT to postback when clicking the add new. The postback takes place when the save button is clicked.

HEllo, as some questions came up here are a few clarifications:

Note: proper DbParameters with placeholders need to be used in the queries else the special characters don't work!!, not just sql, this is standard, also the value column is stored as a Clob since the text can be long, it needs to be converted to and from string, but this should not pose any problems there is a standard Oracle function for this and code on the internet.

The job MUST be done in C#, I forgot to mention this, NOT VB.NET!

Skills required:
.NET, C# Programming, Oracle
