Real-time processing is simply defined as the processing of the unbounded stream of input data, with minimized latency requirements for processing, measured periodically even in seconds or milliseconds.
- Option A is Correct. Real-time processing occurs with very short latency requirements
- Option B is Correct. In real-time processing, the processing of input data takes place periodically with a short turnaround time i.e. seconds or milliseconds.
- Option C is incorrect. In real-time processing, the processing of input data stream takes place with a shorter turnaround time. It is stream processing where processing is done just after the data is created.
- Option D is incorrect. One of the main characteristics of real-time data processing is that the processing of input data stream takes place with the minimized latency requirements to support real-time consumption, so high latency is not acceptable with real-time data processing.
Q2. The mathematical terms Relation and Tuple in relational database respectively represent
A. Table and Domain
B. Table and Row
C. Table and column
D. Key and Row
Explanation:
Correct Answer: B
In a relational database, data is stored in the form of tables. Entities are modeled as tables and each instance of an entity is represented by a row in the table and the column represents the attributes of that entity. In mathematical terms, a table is known as a Relation, and rows are known as tuples.
- Option A is incorrect. In a relational database, a relation refers to the table whereas a tuple represents a row in the table. A domain is the set of permitted values for an attribute.
- Option B is correct. In a relational database, a Relation refers to the table whereas a Tuple refers to the row.
- Option C is incorrect. In a relational database, a relation refers to the table whereas a tuple represents a row in the table. A column represents the set of values of the same data type for various instances of an entity.
- Option D is incorrect. In a relational database, a relation refers to the table whereas a tuple represents a row in the table. There are many types of keys like primary key, secondary key, alternate keys, etc that have their purpose. A primary key is the most common key that uniquely identifies each row in the table.

Q3. Which elements can be used to define the relationship between tables in relational databases?
Explanation:
Correct Answer: B
Primary Keys and Foreign Keys are used to define the relationship between tables. The primary key is responsible for identifying each row in a table and is unique for each row; two rows can never share the same primary key. The foreign key is responsible for the identification of rows in a different, related table. For every value in the foreign key column, there should be a related row with a similar value in the relevant primary key column for the other table.
- Option A is incorrect. The index helps in searching data in a table, and the view is a virtual table that depends on the set of results from a query.
- Option B is CORRECT. Primary Keys and Foreign Keys help in marking the unique identity of each row in a table as well as establishing a relationship between different tables.
- Option C is incorrect. Rows and columns are the basic foundations of a database table and serve their function in organizing datasets in tabular formats.
- Option D is incorrect. Graphs and charts are visualizations of datasets and are primarily based on the subjective opinion of the user.
