I want to design/find a C++ Datastructure/Container which supports two column of data and CRUD operation on those data. I reviewed the STL Containers but none of them supports my requirement (correct me if I am wrong).
My exact requirement is as follows

  1. Datastructure with Two Columns.

  2. Supports the following Functions

    1. Search for a Specific item.

    2. Search for a List of items matching a criteria

    3. Both the column should support the above mentioned Search Operation. ie., I should be able to search for a data on both the columns.

    4. Update a specific item

    5. Delete a specific item
    6. Add new item

I prefer search operation to be faster than add/delete operation.

In Addition I will be sharing this Data between Threads, hence need to support Mutex(I can also implement Mutex Lock on these data separately.)

Does any of the existing STL meets my requirement or do we have any other library or datastructure that fits best to my requirements.

Note: I cant use Database or SQLite to store my data.

Thank you
Regards,
Dinesh

    If one of the column is unique then probably you can use Map. Otherwise define a class with two member variables representing the column and store it in a vector. There are algorithms that will help you in searching the container.
