sql server - Database Table Normalisation -


We are accumulating the content's metadata in database tables. In which there is a column named Keyword containing keywords related to the content, should we normalize the table based on the keyword column because the keyword column will have multiple values.

I do not think the answer to this question is absolutely complex. This is a textbook generalization problem and the answer is yes , you should definitely make it normal.

Storing multiple values ​​in one column first - Normal form (most designers try to get the third - normal) - the only reason for this is Demonstrate performance as a means of optimization, that is, if the database is very large and you are able to use some special sequencing strategy on denormalized columns to close some specific optimization (i.e. physical route). This is not the case here.

Not being normal can be difficult to write the questions and it can be quite impossible in the index. And if you're accumulating the keyword, then I can only assume that the keyword is the reason for Search - so you definitely want to point out this data and write simple questions.

Please - Make your data normal.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
