Step by step
Solved in 3 steps
- A database system has replaced the traditional processing of files. As a consequence of this new database strategy, there are several advantages. Despite its many benefits, the database system has several limitations that should be properly examined.Unlike a database, which stores data, an information system makes use of it. Is there any impact on database design as a result of this relationship?It's important to note that doing a search using keywords on the internet and conducting a search using keywords on a database are two entirely different processes. Both of these things are quite different from one another. What are some of the most significant differences that exist between the two in terms of how the inquiries are expressed and what the results of a query are, and what are some of the most significant similarities that exist between the two in terms of how the inquiries are expressed and what the results of a query are?
- To what extent do the benefits of using a database need to be weighed against the disadvantages?Can an error in a database system be considered more severe than one that happens elsewhere?A database is to be designed for a college to monitor students’ progress throughout their course of study. The students are studying for a degree (such as BA, M.Sc., etc.) within the framework of the modular system. The college provides a number of modules, each being characterized by its code, title, and credit value, module leader, teaching staff and the department they come from. A module is coordinated by a module leader who shares teaching duties with one or more lecturers. A lecturer may teach (and be a module leader for) more than one module. Students are free to choose any module they wish but the following rules must be observed: some modules require prerequisites modules and some degree programs have compulsory modules. The database is also to contain some information about students including their numbers, names, addresses, degrees they study for, and their past performance (i.e. modules taken and examination results).Draw an ER diagram for this database using as much of the…

- Data collection and categorization before database entry are crucial.A database is to be designed for a college to monitor students’ progress throughout their course of study. The students are pursuing a degree (such as BA, BA (Hons) MSc, etc.) within the framework of a modular system. The college provides a number of modules, each being characterized by a code, title, and a credit value. A module belongs to one department and is co-ordinated by a module leader who shares teaching duties with one or more lecturers. A lecturer may teach (and be a module leader for) more than one module. Information about a lecturer include his/her IDNO, Name which is comprised of a surname and first name, Address {StrNo, Zip Code, City} and they are required to have at least two phone numbers. Every lecturer belongs to a given department, and a department hosts at least two modules. Each department has a code, name. Student are free to choose any module they wish but can’t do more than five and less than three and; a module can only be taught if it has more than ten…What are the benefits of reorganising a database system?
