How to manipulate a very large data using QT?

[aurora]

Hi all,
I have a very large data and i want to manipulate(displaying requested part of data) those data providing Qt User interface.
How do i start for this?
What are the requirements?
Do i need to use any database drivers like SQLite or something?

Hello.
What kind of data? If it's textual data (not video or sound) use sqlite for fast lookup.

Ya just text data....
Would u mind to tell how to start with that?
And if i developed a application using sqlite, do the users also need to install that while executing in different machine?

Hi depends on what you want to display, in what context and how the data should be organized.
It might make sense to read the Model/View classes and check out if it suits your needs. The View(e.g. a QTableView) will only request data from the model (your SQL data) that is displayed. That will keep the load to a minimum. Using the QSQLmodel class will help a lot. Never used it myself, but with the tutorial about Model/View it wouldn't take to much time to master.

SQLite is a in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine.

bq. And if i developed a application using sqlite, do the users also need to install that while executing in different machine?

No. SQLite will be a part of your program.
