从数组中 任取一个元素 p (可随机取,现在以取第一个为例).以P作为主元,对数组 进行划分 ,前一部分小于 P,后一部分 大于p.最后划分处存储p,然后分别对划分后的前一部分和后一部分递归调用.
算法平均时间复杂度: O(nlogn)
-Any check from the array element p (can be random access, and now to take the first example). To P as the main element of the array to be divided, the first part is less than P, the latter part of the final division is greater than p. Department store p , and then were divided into the first part and the latter part of recursive calls. algorithm the average time complexity: O (nlogn)

This a simple database management system. It doesn t use any other code (i.e. ODBC, ADO, etc.) and has it s own database file format. I wrote it because I found the other DBMSs code too bulky and hard to debug. It s designed for small applications and I doubt it could handle anything on a large scale. A sample program included in the .zip shows how everything works. The database project is a library project, so you ll have to compile and link with the .lib file to get everything working. Pros: - You have the source code so you know exactly what it is doing - Database files are very small - Small and fast code Cons: - Can t handle large amounts of records (more than 65000ish) - Doesn t support SQL (you have to search the database by cycling through the records and testing them against your constraints) - Each database file can only have one table.
