Disadvantages of CAML over LINQ in SharePoint 2010

Disadvantages of CAML:

Since CAML query is text based, If you are joining two lists accross a lookup field there may be various problems.
you do not know until run time if the query is written correctly. If the query is not correct, then it will simply fail at run time.
It has no IntelliSense support at design time.
When writing the query, you have no idea what CAML elements are legal in the syntax without having a reference open.
The query is difficult to read. You cannot determine easily what the query is doing and what lists are being joined.
The data returned from the query is placed in a SPListItem collection, which does not provide strongly typed business entities.

Advantages of LINQ over CAML:
It is an object-oriented query language.
It provides strongly typed objects at design time, you can create queries in code and know that they are correct because the code compiles.
The strongly typed objects provide IntelliSense at design time, which makes it much easier to construct a correct query.
The results are returned from queries as strongly typed objects, so the items and fields also provide IntelliSense and compile-time checking.

HOW TO CREATE A SHAREPOINT EMPLOYEE DIRECTORY?

Option 1: Use the Contact List Web Part available in SharePoint If you are a small organization, you can simply use an out of the box Web Part called Contacts to manage contact information. The beauty of this approach is that you can customize your Contacts Web Part with any columns/metadata that you wish. That means you can add all sorts of phone numbers, notes, other information and group/organize it in any way you wish on your SharePoint site or page The second option when it comes to SharePoint Employee Directory is to create custom sites/pages using Content Search Web part.
