disks = more axes, which means more parallel I/O, at least in the benchmark world). Now, in the RISC and Sparc World, the 64-bit architecture is becoming a standard, allowing commercial UNIX® such as aix®, HP-UX, and Solaris to provide a large amount of memory for your favorite relational database. 32-bit memory has an addressable capacity of approximately 4 GB, and many UNIX machines have 20 to GB of RAM, and you certainly want to use such a large amount of memory. The Intel world doesn't lag

The basic idea of choosing a sort Each trip selects the smallest record of the keyword from the record to be sorted, placing the order at the end of the ordered sub-file, knowing that all records are sorted. There are two main options for sorting: Direct selection of sort (or simple selection sort) and heap sorting. Direct selection of the basi

Bubble sort (Bubble sort) basic idea: 22 Compare the keywords of adjacent records, if the reverse order is exchanged until there are no reversed records. The time complexity is O (N2).The basic idea of simple Selection sort is to select the smallest record of a keyword from a n-i+1 record and exchange it with the first record by comparing N-i keywords. It should
