    c++ database search

    hi all,

    i have made a database and do sequential searching of it, but i found smart device c++ is different from others since it is so slow to finish the searching. i am a beginner of it, can anyone suggest what can i do for the database searching such as using pointer or redesign of the database?

    thanks!

    Have you considered using an embedded database engine, e.g., SQLite?

    By "database" do you mean a list of data or a relational database. If it's a list you can use and ordered index structure like a binary search tree to make access faster.

    Or if it's a basic array structure, a plain "binary search" [aka "midpoint search"] can be used to search quicker.

    had u tried it? is it faster for searching?

    actually i dun understand why smart device application is so slow for array searching even i run it in emulator on desktop, not on pda, but java or c# can be much faster.
    anybody know why? thanks!
