A Database Management System (DBMS) is a software system that allows you to define, create, maintain, and manipulate databases. It provides a way to store, organize, and retrieve data in a controlled and efficient manner.
(1aii)
(I) Improved data integrity: DBMS ensures that data is consistent, accurate, and up-to-date.
(II) Enhanced data sharing: DBMS allows multiple users to access and share data simultaneously, improving collaboration and productivity.
(1bi) Conceptual approach:
This approach focuses on identifying the entities, attributes, and relationships in the data, without worrying about the physical storage or implementation details. It provides a high-level view of the data, using diagrams and notation to represent the concepts and relationships.
(1bii) Logical approach:
This approach takes the conceptual model and translates it into a logical structure, using tables, fields, and relationships to represent the data. It defines the schema of the database, including the relationships between tables and the constraints on the data.
(1biii) Physical approach:
This approach focuses on the actual physical storage and implementation of the database, including the choice of storage media, file organization, and indexing. It defines how the data will be stored on disk, and how it will be accessed and retrieved.
===================================
(2ai)
Log files:
Log files are records of all events and activities that occur within an organization’s computer systems and networks. They are essential for data security as they provide a trail of evidence in case of a security breach or incident. Log files can help identify Unauthorized access attempts, System vulnerabilities, Malware activity and Data tampering or theft
(2aii)
Firewalls:
Firewalls are network security systems that monitor and control incoming and outgoing network traffic based on predetermined security rules. They act as a barrier between a trusted network and an untrusted network, such as the internet. Firewalls help prevent Unauthorized access to sensitive data, Malware and virus attacks, Denial-of-Service (DoS) attacks and Data breaches
(2b)
(i) Corrective maintenance
(ii) Preventive maintenance
(iii) Adaptive maintenance
(iv) Perfective maintenance
EXPLANATION;
(i) Corrective Maintenance: This maintenance type is reactive. It comes into play when bugs or defects are identified either through user reports or testing. The primary goal is to fix these issues to restore the software’s proper functioning. For example, if users find a bug that causes a crash, corrective maintenance would address this issue to prevent further crashes.
(ii) Adaptive Maintenance: This maintenance type is proactive. It involves making changes to ensure the software continues to operate effectively in new or altered environments. For instance, if a software application needs to run on a newer version of an operating system, adaptive maintenance would involve updating the software to ensure compatibility with that new system.
===================================
(3ai)
A workbook is a file that contains a collection of spreadsheets or worksheets used for data analysis, calculations, and visualization. It is a central component of spreadsheet software like Microsoft Excel, Google Sheets, or LibreOffice Calc.
(3aii)
(i) Navigation: A website typically has a navigation menu or system that allows users to move between different pages, sections, or content.
(ii) Interactivity: A website often includes interactive elements, such as forms, buttons, links, and multimedia content, that enable user engagement and feedback.
(3bi)
TABULATE
=PARALLEL OPERATING SYSTEMS=
(i) Operates on a single machine with multiple processors.
(ii) Manages resources within a single system
=DISTRIBUTED OPERATING SYSTEMS=
(i) Operates on multiple interconnected machines
(ii) Manages resources across a network of systems.
(3bii)
A determinant in a database table is a column or set of columns that uniquely identifies each row in the table. It is also known as a primary key or unique identifier. The determinant ensures that each row can be distinguished from others, even if there are duplicate values in other columns.
===================================
(4ai)
(i) A workbook is a collection of multiple worksheets, whereas a worksheet is a single page or spreadsheet within a workbook.
(ii) A workbook can contain multiple related or unrelated worksheets, whereas a worksheet is a self-contained entity with its own data, formulas, and formatting.
(4aii)
(i) Creating engaging and interactive presentations for educational or training purposes.
(ii) Developing persuasive sales pitches or marketing materials for business or product promotion.
(4bi)
(i) A compact disk is an optical storage medium that uses laser technology to read and write data while A flash drive is a portable electronic storage device that uses flash memory to store data.
(ii) Data on a CD is read by a laser beam, and once data is written, it cannot be altered. Some CDs are writable (CD-R) or re-writable (CD-RW), but they still have limited update capabilities while Data on a flash drive can be easily read, written, and erased, making it a versatile and flexible storage option.
(4bii)
(i) First Normal Form (1NF)
(ii) Second Normal Form (2NF)
EXPLANATION
First Normal Form (1NF): In 1NF, each column in a database table must contain atomic values, meaning each field should hold only a single piece of data and each record should be unique. For example, in a table listing students and their subjects, if a column contains multiple subjects separated by commas, it would violate 1NF. Instead, each subject should be stored in a separate row or table to adhere to 1NF.
===================================
(5ai)
