Logic: According to the General electrical business model class, the order generally includes order and Order Details class (Detailorder), the two tables are related to the foreign key order_id, so is the relationship between the die and die, s

Requirements Analysis:There is a factory, there are many agents (merchant or door first), before the merchant purchase, inventory, sales, customer information, such as records in the Excel tableOr no records, the management is more chaotic, the profit is unclear. Unable to effectively understand store operations and customer tracking recordsManufacturers also can not be in real time to understand the following agents operating conditions and

Background:I last time to apply for campaign PHP backstage, because the project on the line after some period of time to claim too many people, resulting in some counters inventory is negative (), fortunately the concurrency is not particularly large, Only in a small number of counters and is generally-1 of the situation, not particularly serious consequences, but still have to reflect on their own fault.This time again there is a new claim campaign,

Today, some of my understanding, to tidy up the problem, and hope that the future of such

are complementary concepts. On the one hand, abstract the behavior of the object. On the other hand, encapsulation focuses on the details of the object's behavior. Encapsulation is typically done by hiding the internal state information of an object, so encapsulation can be seen as a strategy to provide abstraction.Common Java Issues1. What is a Java virtual machine? Why is Java called a "platform-agnostic programming language"?A Java Virtual machine is a virtual machine process that can execut

Problem Description: Find out the remaining stock of all items in the store according to the store ID? Business Description: The item's remaining stock = The total inventory record of the goods and-the total sales of the goods and. The database table structure after abstraction is as follows: Question abstraction: Use MySQL to check the remaining inventory information for all items in store 1th? Than

Manufacturing enterprises can be divided into ETO, ATO, MTO and MTS according to the characteristics of enterprise production organization (by single design, by single assembly, by single production and inventory production) four production types. Design by Order (Engineer To Order, ETO) In this production type, a product is designed to a large extent according to the requirements of a specific customer, therefore, supporting custom design is an impor

Mard records the current inventory quantity, but the period is not necessarily the current month. For example, if your materials have not changed the inventory quantity during the entire month in March (the item is not released after the item is confiscated), you can check that the number of entries in Mard is still in March, not in March.When goods are moved during a period, the system updates the MARD dat

is used to contact a database. Although SQL cannot be used to build applications, it can be used to manage data in applications that use a relational database management system (RDBMS).Employment OpportunitiesWell, now that you have a little knowledge of programming languages, you may have a little bit of understanding of what they call difficulty. However, not all languages have the same needs or salaries. If you're learning to program to get jobs,

engineers generally do not remotely manage computers, need to provide information such as log the larger the disk space, the slower the reading speed, You can consider using multiple hard disks to make up a larger space partition just on the hard disk to do the identification, rather than the format in the file system features, so speed faster hard disk faster than the outside speed [partition number is smaller, the outer region, so the volume of data large first partition].
