Forum Discussion about pros and cons of Conventional File Processing System

I have stored some data in a text file edited by notepad which is a conventional file processing system.
For that, I have experienced some advantage and disadvantages of the conventional file processing system.
Advantages :
1. Editing: I can easily edit the information.
2. Sharing: I can share that file in a network to multiple users at a time.
3. Data Retrieval: Computer-based systems provide enhanced data retrieval techniques to retrieve data stored in files in an easy and efficient way.

Disadvantages:
1. Security: the whole data are visible to all user.
2. Data Redundancy: It is possible that the same data are stored in various files.
3. Data Inconsistency: Because of Data Redundancy It is possible that various copies of data in a database no longer agree.

Duplication of files on conventional file systems is very common. For instance, say you download a PDF so you can read it later. However, when you go back to read it, you can't find the document among the dozens of files on your hard drive. Naturally, you download the document again but this time you place it in a location you can find.
if you are composing an email, a window that displays recently edited documents would be useful. This doesn't happen because files created by one application are kept private to that application (Microsoft Word files are only "sensed" by Microsoft Word). In this way the file system limits productivity and data integration.
All hard-disk space is limited, meaning that over time, file space diminishes until data can no longer be stored on the drive. Conventional file systems are capable of compressing files, while still permitting applications to access data. The operating system automatically decompresses the file when needed and compresses it again when the file is closed or saved. This is a powerful advantage, particularly for systems with limited storage space

Advantage & Disadvantages of File Processing Systems:

Advantage:
1. Privacy: - Limited access means privacy of data.
2. Easy access to data – Database systems manages data in such a way so that the data is easily accessible with fast response times.
3. Flexible: - Database systems are more flexible than file processing systems.

Disadvantages:
1. Program-Data Dependence. File descriptions are stored within each application program that accesses a given file.
2. Excessive Program Maintenance. The preceding factors create a heavy program maintenance load.

In a conventional file processing system it is very common to found same thing more than one time. Suppose that now for the online classes we use BLC for receiving all the lecture materials and their video files as well. Here we face the problem after downloaded the whole files. The files are downloaded in one place and we are not to able to find one specific of those files because there may be many files obtaining the same name and when we did not able to find them we need to redownloaded these files.
Advantages: we can easily download a file a store it by the predefined way. And there is no option to lost the data because if we deleted the data we may find it in recycle bin.
Disadvantages: Here we see the data redundancy problem when we store the data in another folder and after that we again tried to download these files again.
Here we also face data isolation problem because these data may have different format and we need to use different programs for that.
Here we also face security problem because when we need to make a discussion with anyone he able to see the whole data.
