功能介紹: l 輸入進程P總共有的頁面數,l 并輸入系統已經在內存中分配的頁面數。當所分配的頁面數大于進程P的頁面數時,l 則不l 需要進行頁面調度工作。 l 由進程P的頁面數目,l 程序隨機生成一些訪問內存的頁面號,l 為簡化程序,l 這些頁面號的數目同l 進程P的進程數目一致(這個缺陷也有待改進)。 l 由用戶選擇FIFO算法還是LRU算法對進程P的頁面訪問內存分配的頁面進行分配,l 并輸出具體的頁面訪問過程。 原理介紹: 請求頁式管理中的置換算法:置換算法在內存中沒有空閑頁面時調用。它的目的是選出一個被淘汰的頁面。如果內存中有足夠的空閑頁面存放所調入的頁,則不必使用置換算法。 先進先出算法FIFO:該算法總是選擇在內存駐留時間最長的一頁將其淘汰。其認為先調入內存的頁不再被訪問的可能性要比其他頁大,因而選擇最先調入內存的頁換出。 最近最久沒使用頁面淘汰算法LRU

This project attempts to implement a Database using B+Tree. The project has developed a DATABASE SYSTEM with lesser memory consumption. Its API includes simple SQL Statements and the output is displayed on the screen. Certain applications for which several features of existing databases like concurrency control, transaction management, security features are not enabled. B+Trees can be used as an index for factor access to the data. Help facility is provided to know the syntax of SQL Statements.
