Why server-side programming matters in PostgreSQL - Quick Recap

Recall & Review

beginner

What is server-side programming in the context of databases?

Server-side programming means writing code that runs on the database server to manage data, process requests, and enforce rules before sending results to the user.

Why is server-side programming important for security?

It protects data by controlling access and validating inputs on the server, preventing unauthorized actions and attacks like SQL injection.

How does server-side programming improve performance?

It reduces the amount of data sent over the network by processing data on the server, sending only the needed results to the client.

Give an example of a server-side programming feature in PostgreSQL.

Stored procedures and functions written in PL/pgSQL that run inside the database to automate tasks and enforce business logic.

intermediate

What role does server-side programming play in data consistency?

It ensures data stays accurate and reliable by enforcing rules and transactions directly on the server before changes are saved.

What does server-side programming primarily help with in databases?

A Managing data and enforcing rules on the server

B Designing the user interface

C Running code on the user's device

D Creating graphics for the website

Server-side programming runs on the database server to manage data and enforce rules.

How does server-side programming improve security?

A By storing data on the user's computer

B By making the website load faster

C By validating inputs and controlling access on the server

D By creating colorful buttons

Validating inputs and controlling access on the server prevents unauthorized actions and attacks.

Which PostgreSQL feature is an example of server-side programming?

A Stored procedures

B HTML forms

C CSS stylesheets

D JavaScript animations

Stored procedures run inside PostgreSQL to automate tasks and enforce logic on the server.

Why does processing data on the server help performance?

A It stores data on the client device

B It makes the client computer faster

C It changes the color of the webpage

D It sends only needed results to the client, reducing data transfer

Processing on the server reduces network load by sending only necessary data.

What does server-side programming do to keep data consistent?

A Sends data to the client without checks

B Enforces rules and transactions before saving changes

C Deletes old data automatically

D Changes data randomly

It enforces rules and transactions on the server to keep data accurate and reliable.

Explain why server-side programming is crucial for database security and performance.

Think about how the server protects data and handles requests.

Describe how PostgreSQL uses server-side programming to enforce business logic.

Focus on code that runs inside the database.
