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.

A方向和B方向各設(shè)紅(R)、黃(Y)、綠(G)和左拐(L)4盞燈,4種燈按合理的順序亮滅,并將時(shí)間以倒計(jì)時(shí)的形式顯示出來。同時(shí)要設(shè)置兩個(gè)方向的緊急通道模式,當(dāng)某一方向有緊急事件發(fā)生時(shí),交警按下緊急通道按鈕,該方向綠燈亮,另外一個(gè)方向紅燈亮,等緊急事件解除后(假定計(jì)時(shí)10s),交通恢復(fù)原來的狀態(tài) 要求在數(shù)碼管上顯示兩個(gè)方向的燈種和計(jì)時(shí),實(shí)現(xiàn)緊急情況按鈕輸入功能 根據(jù)交通燈控制要實(shí)現(xiàn)的功能,可考慮用兩個(gè)并行執(zhí)行的always模塊(兩個(gè)進(jìn)程)來分別控制A和B兩個(gè)方向的4盞燈。這兩個(gè)always模塊使用同一個(gè)時(shí)鐘信號(hào),以進(jìn)行同步,也就是說,兩個(gè)進(jìn)程的敏感信號(hào)時(shí)同一個(gè) 每個(gè)always模塊控制一個(gè)方向的4種燈按如下順序點(diǎn)亮,并往復(fù)循環(huán):綠燈-黃燈-左拐燈-黃燈-紅燈,燈亮的時(shí)間由自己設(shè)定 由于板上資源有限,如覺得實(shí)現(xiàn)困難,可去掉左拐燈,即順序?yàn)榫G燈-黃燈-紅燈。
