Subj : format for data storage? To : comp.programming From : js5895 Date : Wed Jul 27 2005 10:23 pm I need to store a lot of data(mostly text files) into a single file. I programmed a interface that is a hierarchical tree (shown below) What format should I store the data so I can access it through the interface, maybe ZIP, a Database, or other. I looked at B-trees, BTW, my file system is NTFS. The program MyInfo seems to put all the data into a single ZIP file. Databases seem to be better chose but, I don't know. Please help me find a solution. Thanks, for your help and your time, Josh Node A1(2090kB) Node A2(45kB) Node A3(20kB) Node B3(15kB) Node A4(10kB) Node B2(900kB Node C2(450kB) Node A3(400kB) Node D2(50kB) Node E2(200kB) .
