Material database management system based on heterogeneous multi-processor and computer embedded system

摘要

The development of different Data Base Management System (DBMSs) and computer networks and the proliferation of communication led to an increase in the distribution of DBMS network displays. Major diversity issues and challenges include Different types of information, different types of rules and semantics, different DBMSs (recycling, etc.). Address here is a long-term goal of a diversified Database Management System (DBMS), no node. The network, where the user can give an integrated and customized view or mode, cannot support the data. It resides in a single database or database, managed separately by the same DBMS type (according to a single user claims) or by different DDBMSs. The main way to go about data sharing and access: downloading / loading and downloading to the computer from existing top business files and databases created as a result and long-distance desire in the existing DBMS, common interface. Covers are also an item of commercial availability that can become a problem with motivational installation, opportunity cost, and the need to share data with a diverse world. These platforms are partly part of the long-term goals that major research and development projects seek to develop. The calculations were first done on desktop-based systems, and therefore data-based. However, embedded time-dependent systems are required to measure the output events or output events of a given period, run at regular intervals, and more widely. Embedded course Advanced course basket is an effective teaching time-related program. Programming early learning habits are difficult to break in the current situation. Introducing time-related programs for beginners or sophomores, involving a balance between abstraction and resource awareness can provide a good foundation. Combined with a clean microcontroller and a timer, the synchronous state machine calculation model can provide such a balance.
