SOAP Protocol
Simple Object Access Protocol was the only protocol supported for Microsoft Dynamics NAV 2009. This protocol is still used on Microsoft Dynamics NAV 2013 as it provides a powerful tool to either insert or retrieve data from Microsoft Dynamics NAV. SOAP Web Services use port 7047 by default on Microsoft Dynamics NAV 2009.Port 7047 is still used in Microsoft Dynamics NAV 2013.

Therefore, SOAP protocol stays exactly the same allowing us to consume Pages and Codeunits as Web Services.
Let us take a look at Web Services Page from where we can choose which objects to publish as Microsoft Dynamics NAV Web Services:

Both Pages and Codeunits are still available to be chosen and this is part of what the SOAP protocol brings to Microsoft Dynamics NAV.

ODATA protocol

OData protocol is part of the new features Microsoft Dynamics NAV 2013 has. Let us start by defining what ODATA is and then we will take a closer look on what can be accomplished through Odata in Microsoft Dynamics NAV.
The Open Data Protocol (OData) is a Web protocol for querying and updating data that provides a way to unlock your data and free it from silos that exist in applications today. OData does this by applying and building upon Web technologies such as HTTP, Atom Publishing Protocol (AtomPub) and JSON to provide access to information from a variety of applications, services, and stores.

To keep talking about OData and Microsoft Dynamics NAV we would have to talk about the new Microsoft Dynamics NAV object that has been introduced on Microsoft Dynamics NAV 2013: Query object.
A query is a new object in Microsoft Dynamics NAV 2013 that you use to specify a set of data from the Microsoft Dynamics NAV database. You can query the database to retrieve fields from a single table or multiple tables. You can specify how to join tables in the query. You can filter the result data. You can specify totaling methods on fields, such as sums and averages.

OData WS have their own port as seen previously and also have their own configuration space (this can be viewed in the new Microsoft Dynamics NAV 2013 Administration console).

If we now take a look at Web Services Page again we can see how Query object are also eligible to be published as WS (In Read-Only mode) and this will be using OData protocol (Pages will also be eligible under OData protocol but just as a read only one):
