Large Structs

[dmoore210]

I am creating a project that will allow a user to keep track of all the products that we create. I have to create a struct to keep all the data for each product we make. Here's the struct.

struct PRODUCT_DATA {
    int    IL;         
    int    freq;      
    int    serial;    
    int    date;
    bool   recal;        
    double CorrFacVal;     
    double CorrFreq;     
    double std_diff;          
    double error;          
    double IL_d_3;    
};

The problem: For each product we make, it get's it own struct worth of data. I can't declare the amount of structs that I need, it's too large to be put on the stack.

The usage: (We have around 500k worth of products that we have made and each of them needs their data stored). MyProduct[500000];

When the program is loaded up it will read from a CSV file that will input each product into it's own struct and from there I can modify any existing product, search through them to recover data about it, add more products, or delete products.

Question: Is there a better way to do this? I've looked at SQLite although that seems a bit overkill for what I am trying to do, and a bit complicated for my skill level. I just need one very large array of structs. Around a 500,000k array of these structs.
