I. Introduction of electronic commercial bill of Exchange system:

is to point out that the Drawee relies on the electronic commercial bill of Exchange system, in the form of data messages, entrusted to the payer on the appointed date of unconditional payment of the amount determined to the payee or bearer of the ticket. That is, to achieve a commercial bill of business operations completely electronic, in the course of business operations, no physical instrument flow, all data messages through the People's Bank electronic commercial bill of Exchange system and access to the bank, the financial company's electronic bill system in circulation and is processed.

Ii. introduction of the course

This series of lectures mainly describes how to use the Struts2,hibernate,spring architecture to build enterprise application solutions, the front desk with ExtJS presentation is divided into two parts.

The first part introduces the business of electronic commercial bill of Exchange system.

The second part, the actual application (a bank-e-commerce Bill of Exchange system) as an example, to ExtJS as a front-page display, according to the requirements analysis and planning, design and implementation----deployment and application----operation and maintenance of ideas, This approach is one of the best ways to quickly master a technology and banking business.

Iii. Introduction of development:

1, ExtJS related to the client-side technology.

2, a comprehensive understanding of how to develop a complete and efficient bank MIS system complete development process.

3, the use of software development necessary tools: Xmanger application, frame construction and use, AIX under the ECDs deployment, JUnit unit testing, log4j for log tracking and so on.

4, in-depth understanding of spring technology, understand the three-tier architecture ideas, ExtJS, and write shell script backup, clear data and so on.

5. Understand the demand analysis, development, operation and maintenance, performance improvement and security management of electronic commercial drafts in the bank.
