Differences Between NDM and FTP
There are several ways that the exchange of files between two computers can be done. In most cases, information will be seen from one computer which is the user, and the other computer receiving the information which becomes the client. There is a need to check on an acceptable protocol to use to allow for a seamless exchange. There are two main exchange protocols that can be used. One of these is the FTP and the other NDM.
“FTP” is an acronym that stands for “file transfer protocol.” This protocol is by default the standard mode of exchanging information between two computers, mainly the user and the server. The technology behind the use of FTP is that one of the ends of the exchange ought to act as a client while the other end must act as the server. Upon request from the client to server, the server has been programmed to either allow or disallow the client access. In the event that the client is granted entry, they can get files from the server which is commonly referred to as downloading. To place files, this process is known as uploading.
“NDM,” on the other hand, refers to network data mover, a name that has stuck since its inception. Ownership of the company has changed through time to Sterling Commerce, and the new name used in reference to NMD is CONNECT: Direct. The main use of NDM is to help in the automation of the file exchange between the client and the server.
Due to its automated feature, NDM is a great resource to use when dealing with large data packets. An example is financial companies that are constantly working on collecting data. Automation of exchange of data makes work quite easier as opposed to an FTP file transfer. This is a good welcome for those who prefer the traditional method of entering data from a client end and uploading it up to the server. If the data being transferred is highly sensitive, NDM allows for encryption of the data being sent to ensure data integrity. This is not a feature that is ordinarily available in FTP.
Although comparing performance, you might find NDM and FTP to offer more or less the same services. NDM is a step ahead because when uploading or downloading data to the server, it employs a unique compression feature. The feature is important as a comparative scrutiny between the two shows that less bandwidth is utilized by NDM as opposed to FTP and thus NDM may be faster.
Another important feature of NDM over FTP is that it offers a checkpoint restart, a feature not available in FTP. Further, it offers integration and added management tools which allows for the automation of different aspects of the client production environment. This is a great help, especially with regards to logging of all file transfers which makes auditing quite easy.
