54. Programming 2 : Records

What is the primary purpose of storing data in text files according to the video?

• To store data permanently when the application is closed

• To enhance the speed of data retrieval in multi-user environments

• To secure data against unauthorized access

• To store large volumes of data efficiently

What happens if the data in a simple text file is not stored in the correct order?

• The data becomes encrypted

• The program will fail to work due to data dependency

• The program becomes more efficient

• Multiple users can access the data simultaneously

What is a disadvantage of storing data in arrays or lists in memory?

• Data can be accessed by more than one user on a different computer at a time

• It is less secure than storing data in databases

• It is suitable for large data sets

• Data stored like this can't be accessed by more than one user on a different computer at a time

What type of storage is used for larger data sets or records in a structured way?

• Simple text files

• Arrays or lists in memory

• External databases

• RAM

Which language is mentioned as not supporting the record data structure?

• Java

• Visual Basic

• Python

• SQL

What is the first step in using the record data structure if your language supports it?

• Encrypt the record for security

• Define the record structure

• Assign and retrieve data from the variables inside the record

• Declare a variable or an array to use with the record structure

What syntax is used to assign variables to a record data structure?

• Bracket syntax

• Dot syntax

• Comma syntax

• Colon syntax

What is a characteristic of data stored in databases?

• It can only be accessed by one user at a time

• It is stored in a non-structured way

• Many users can access the data from different computers at the same time

• It is less secure than storing data in simple text files

What is the role of SQL mentioned in the context of databases?

• To enhance the programming speed

• To create graphical interfaces

• To manipulate and access data

• To encrypt data

What is the main advantage of using record data structures?

• They allow for data to be stored in a non-structured format

• They support the storage of large volumes of data in RAM

• They collect related fields together, where each field can have a different data type

• They enable multiple users to access the data simultaneously
