A primary key is a column or combination of columns that contain values that uniquely identify each row in the table. It enforces the entity integrity of the table and prevents the insertion of duplicate rows. A table can have only one primary key, which is usually defined on an identity column or a column with not null and unique constraints.A primary key also creates a unique index for the table, which allows fast access to data when the primary key is used in queries12.Reference:1: Primary and Foreign Key Constraints - SQL Server12: Primary and Foreign Key in SQL With Examples - DataFlair2

In object-oriented approach, a program is composed of classes and objects that interact with each other through messages. A class is a blueprint that defines the attributes and behaviors of a group of similar objects. An object is an instance of a class that has its own state and can perform actions defined by the class. Objects can be related to each other through different types of relationships, such as inheritance, association, aggregation, and composition. Object-oriented approach aims to model the real-world entities and problems in terms of objects and their interactions, making the program more modular, reusable, and maintainable.Reference:Object Oriented Approach - Online Tutorials Library,What is object-oriented programming?

The conceptual level is a high-level description of the data and its relationships in the database, without specifying how the data is physically stored or implemented. It defines the main entities, attributes, and constraints for the entire database, and is independent of any specific database management system or application. The conceptual level is also known as the logical level, and it is usually represented by an entity-relationship diagram (ERD).Reference:Conceptual schema - Wikipedia,Navigating the Three Levels of Database Design: Conceptual, Logical, and Physical

According to the CITM course outline1, there are five data collection techniques that are commonly used in business analytics. They are:

Observations: This technique involves watching and recording the behavior, actions, or events of interest. Observations can be either direct or indirect, structured or unstructured, participant or non-participant.

Interviews: This technique involves asking questions to individuals or groups of people who have relevant knowledge or experience on the topic. Interviews can be either structured, semi-structured, or unstructured, depending on the level of flexibility and standardization of the questions.

Surveys: This technique involves administering a set of questions to a sample of respondents who represent the population of interest. Surveys can be either quantitative or qualitative, depending on the type and scale of the questions.

Focus groups: This technique involves gathering a small group of people who share some common characteristics or opinions on the topic and facilitating a discussion among them. Focus groups can be used to explore attitudes, perceptions, feelings, or preferences of the participants.

Documents: This technique involves reviewing and analyzing existing documents or records that are relevant to the topic. Documents can be either primary or secondary, depending on the source and authenticity of the information.

A malicious program that records a user's keystrokes is an example of aTrojan horse. A Trojan horse is a type of malware that masquerades as a legitimate file or application, but secretly performs malicious actions in the background. A Trojan horse can be used to install other malware, such as keyloggers, on the victim's device. A keylogger is a specific type of Trojan horse that captures and sends the user's keystrokes to a remote attacker, who can use them to steal sensitive information, such as passwords, credit card numbers, or personal data.

The other options are not correct because:

Adware is a type of malware that displays unwanted advertisements on the user's device, often redirecting them to malicious websites or installing more malware. Adware does not necessarily record the user's keystrokes, although some adware may have keylogging capabilities.

An anti-virus program is a software that protects the user's device from malware, such as viruses, worms, ransomware, spyware, etc. An anti-virus program does not record the user's keystrokes, but rather scans and removes any malicious programs that may do so.

A performance monitor is a software that measures and displays the performance of the user's device, such as CPU usage, memory usage, disk space, network traffic, etc. A performance monitor does not record the user's keystrokes, but rather provides useful information for troubleshooting or optimizing the device.
