What is the main problem found in a traditional file environment that was solved by the relational database management system?
Different functional areas and groups were allowed to develop their own files independently.

What are the characteristics of traditional database?
Characteristics of structured data include the following: Clearly defined fields organized in records. Records are usually stored in tables. Fields have names, and relationships are defined between different fields.
Why data quality audits and data cleansing are essential?

What are the problems with traditional file system?
Problems resulting from the traditional file environment include: Data redundancy: duplicate data in multiple files, leading to data inconsistency, different values used for the same attribute. Program-data dependency: Changes in programs requiring changes to the data. Lack of flexibility.
What is a traditional file system?
The traditional filing system (TFS) is a method of storing and arranging computer files and the information in the file (data). Basically it organizes these files into a database for the storage, organization, manipulation, and retrieval by the computer’s operating system.
How does database approach differ from traditional file system?
In database approach, a single repository of data is maintained that is defined once and then accessed by many users. … But in traditional file processing system the application is developed for a specific purpose and they will access specific database only.
Why DBMS is so powerful?
Relational databases are powerful because they require few assumptions about how data is related or how it will be extracted from the database. As a result, the same database can be viewed in many different ways. An important feature of relational systems is that a single database can be spread across several tables.
How does the database overcome the problems faced by the file based information systems?
There are several advantages of Database management system over file system. Few of them are as follows: No redundant data: Redundancy removed by data normalization. … Each user has a different set of access thus data is secured from the issues such as identity theft, data leaks and misuse of data.
What are the 3 types of filing systems?
