maintaining security of data
The database approach offers several advantages over the file processing approach. Firstly, databases provide a central repository for data storage, allowing for better data organization and easier access. Secondly, databases allow for efficient data retrieval and manipulation through query languages, enabling users to extract relevant information quickly. Lastly, databases offer data integrity and security features, ensuring that data is protected from unauthorized access or modification.
A database approach is a method of managing and organizing data using a structured repository that allows for efficient retrieval, storage, and manipulation of information. On the other hand, a file-based approach involves storing data in separate files and organizing them manually, which can result in redundancy, data inconsistency, and limited accessibility compared to a database system.
Two advantages of using a database over paper are increased data security through user access control and faster data retrieval through querying capabilities. Additionally, databases allow for easier data manipulation and organization compared to paper records.
The traditional approach to data management typically involves manual record-keeping in physical files or documents. In contrast, the database approach uses digital databases to store, organize, and retrieve data efficiently. Databases allow for structured data storage, easy data manipulation, and improved data security compared to traditional methods.
Using a database approach allows for structured storage and organization of data, which enables faster retrieval and efficient querying. With indexing and optimized data models, databases can provide quicker access to specific information compared to non-database approaches like spreadsheets or flat files. Additionally, databases support relational data modeling, which allows for complex relationships and joins between different data sets, enabling deeper insights and analysis.
Some advantages of having student enrollment information on a computerized database include: Improved organization and efficiency: Information can be easily sorted, searched, and updated, saving time and effort compared to manual record keeping. Enhanced accuracy: Computerized databases can minimize human errors, ensuring reliable and correct information. Easy accessibility: Authorized personnel can access the database remotely, allowing for efficient collaboration, sharing of information, and generating reports.
what are the advantages of database management approach to the file processing approach Give examples to illustrate your answer

The advantages of Cost and Risk Database Approach include being personalized and specialized. It also involves conversion costs and management cost.
•Database approach: approach whereby a pool of related data is shared by multiple application programs; offers significant advantages over traditional file-based approach
The Database Approach has four common characteristics. These are: Self-describing nature, support multiple user view of data, share the data and multiple user transaction processing and insulation between data and data abstraction.
Advantages to database approach to storing includes everything is in the same place, you can store data tightly and employees can easily retrieve the information. When everything is stored somewhere else, it takes too long to retrieve the information.
One of the advantages of a relational database model is that the broken keys and records and the data complexity are usually simplified. The disadvantage of the relational database model is that it requires sophisticated processing power which is very costly.

Briefly, file processing is the act of creating, storing, managing and readingfiles containing data on your computer. File processing allows you to create a new file, for example, a written document, a picture or a poster. In order to create a new file, you must put data into a blank file and save it. File processing allows you to open files that you have already created and stored on your computer, in order to read through them. However, file processing usually does not allow you to edit content within the files, as thefiles are opened on a read only basis.On the other hand, database management is a piece of software which allows you to create and maintain a collection of digital data on your computer, otherwise known as a database. Database management software is commonly used in large scale businesses and organizations, where thedatabase administrators are granted a large degree of control over thecreation and management of data within a database.Database management is superior to file processing for a number of reasons:• It allows a number of users to access the same pieces of data at the same time - for example, three people on different computers can access thesame word file simultaneously through database management• It allows files to be edited and changed while file processing does not - for example, you may be unable to make amendments to a spreadsheet using file processing• It allows certain people or users of the database, called administrators, to have more control than other users, whereas in file processing, all users have the same amount of control
