Data independence is lacking in file systems because they often store data in a format that is tightly coupled with the applications that use it. This means that changing the structure or format of the data requires modifications to the applications, leading to a lack of flexibility and interoperability. In contrast, databases offer better data independence by separating the physical storage of data from the logical representation, allowing for easier modifications without impacting applications.

What is data independence and why is lacking in file systems?

Data independence is: • A type of computerized database system that keeps data separate from other computer programs that make use of that particular data. • A key feature of data independence is ensuring that the data cannot be recognized by other programs on the system. • The information can still be accessed from another point on the system but not though specific programs. • It simplifies the management of a complex database system which may in turn make staff become more productive as information is easier to locate. This is due to data access becoming improved and the system being made more user-friendly. • The storage structure of the information by other applications becomes restricted to prevent the stored data from becoming corrupt. • This type of system may be useful in an environment where more than one database is in place. It makes keeping and maintaining the information found on either a single or multiple database in one office space much easier to control. • If a workplace does not have data independence systems in place, files become inflexible and some information may become corrupt by other programs. Other programs will be prevented from being able to access the data when programs in the source code are processed and lack data independence.


What are the two method used in data processing systems for organizing data?

The two methods used in data processing systems for organizing data are database systems and file systems. Database systems use structured data models and provide a logical organization of data through tables, allowing for efficient storage, retrieval, and manipulation. File systems, on the other hand, organize data in files and folders, providing a hierarchical structure for storage and access.


What is the similarities between traditional file system and database system?

Both traditional file systems and database systems store and organize data in a structured manner. They both provide mechanisms for data retrieval and manipulation, and offer a way to manage and secure data. Additionally, both systems require a schema or structure to define how data is organized and related within the system.


What is a fact concerning the master data file?

The master data file contains consolidated and centralized data that serves as the primary source of information for an organization. It typically includes key data elements such as customer, product, and supplier information, ensuring consistency and accuracy across multiple systems and departments.


Discuss the main characteristics of the database approach and how it differs from traditional file system?

Databases store electronic representations of data, but traditional file systems generally store paper with data written on it. In a traditional file system a file folder is the the way records are grouped, but in a database records are indexed in many ways, both by "file folder" and by record or data field. With relational database approaches relationships can be established between data in records and new records can be created from crossing files and even databases.

What are the two major weaknesses of file-processing systems?

Traditional file processing systems include manual systems and also computer based file systems that were linked to particular application programs. This is the type of file processing that you used with your 3GL programming. They share a number of characteristics.

How modern databases evolved from file systems?

Modern databases have evolved with technology. They have gone from simply file systems to multimedia database systems. Unlike before, everything is saved in a database now.

Compare Database Systems and File Systems?

File system has data stored in flat files, which stores only processed data. Database system has data stored in table and they may or may not be related to each other. Database system is more efficient and also reduce redundant information which file system can not do.


What are the problems of managing data in a traditional file environment?

•Data redundancyDifferent systems/programs have separate copies of the same data •Program-data dependence All programs maintain metadata for each file they use •Lack of flexibility Programmers must design their own file formats •Poor security, lack of data-sharing and availability No centralized control of data •Excessive Program Maintenance 80% of of information systems budget


DBMS has replaced the traditional file system?

Yes. Database Management Systems (DBMS) have replaced the traditional file based data storage systems. This is because they are:More powerfulEasier to manangeCan store large volumnes of dataManipulation & fetching of data from a DBMS is many times easier than doing so from a file based data storage systemFaster
