leasing system
Abstract
With the development of the economy and the improvement of people's quality of life,
people have the conditions to buy more and more favorite items. But the increase in items has
led to some of them being left unused, and many items have either been left in corners and no
longer used, or sold as scrap. At present, the rapid development of the Internet has provided
people with another way to deal with idle items, which is to sell or rent them online.
On this basis, the second-hand items purchase and leasing system has been developed,
the system is to combine the purchase and rental of second-hand items, user needs, item
information, required technology to achieve, through the system to achieve second-hand items
release, management, review, search, purchase, lease and related data query statistics and
other functions.
The system is divided into a front-end module and a back-end module in terms of
function, in which users can register their personal information, log in and publish the
second-hand items they need to sell, and after passing the review, they can be displayed in the
front desk, and can be queried according to the name of the second-hand item and the
classification of the item. You can also complete the purchase and leasing of second-hand
items, and after the purchase of the transaction, you can update the status to confirmed
transaction, and when you cancel the lease, you can automatically complete the calculation of
the number of lease days and fees, and update the rental status to Cancelled. In the
