Compared with the rise of small and medium-
sized supermarkets, large supermarkets are far away
from residential areas, making shopping less
convenient. Especially in the purchase of daily
necessities, large supermarkets are not only large in
size and variety, but also have the problem of long
queues, which makes residents unwilling to spend too
much time and energy to go to large supermarkets.
This is where the advantages of small and medium-
sized supermarkets come into play, as they are usually
very close to residential areas and may even be
located downstairs. The "small but fine" business
model is also a good fit for consumers' immediate
shopping needs.
To solve the problem of long checkout lines in
large supermarkets due to low checkout rates, Gilbert
mentioned in his paper the use of an automated
supermarket self-checkout system based on Radio
Frequency Identification (RFID) (Gilbert, 2021). It is
a wireless communication technology used to identify
and track the information carried on a tag. It usually
consists of two parts: a tag and a reader. The tag is
attached to the item and is used to store and transmit
data. The reader communicates with the tag by
sending a radio signal and reads or writes the data.
This system can improve checkout efficiency and
give customers a better shopping experience (Gilbert,
2021). The system consists of a hardware module, a
database module and two user interface modules. The
hardware module is responsible for reading the
unique identification number of the product tag, the
database module contains the product information
update, and the user interface module interacts with
the cashier and the customer to display the purchase
list and the payment amount (Gilbert, 2021). With
this system, when the customer puts the goods into
the shopping cart, the RFID reader can automatically
read the information on the tag and totalize the price
of the goods in the shopping cart (Gilbert, 2021).
Also, the customer can push the shopping cart to the
self-checkout counter. The system will automatically
read the information of the products in the shopping
cart and generate the bill (Gilbert, 2021).
However, small and medium-sized supermarkets
also have shortcomings in operation. There is a big
gap between small and medium-sized supermarkets
and large supermarkets in terms of the strength of the
overall group, the management model and the
management of goods in and out (Mao, 2019). And
small and medium-sized supermarkets generally do
not invest too much resources and energy in MIS.
Therefore, it has fewer opportunities for trial and
error, and they need a suitable and efficient MIS to
more accurately grasp the business situation and the
development trend of today's commodities. In order
to better adapt to the development and maintain their
own competitiveness. In this research, Tongda
constructed a chain of convenience store MIS based
on B/S architecture by using 'HDFS', data warehouse'
Hive Metastore', and distributed computing
framework 'Spark' (Tong, 2017). This system makes
the management of convenience stores more
systematic and scientific, which is helpful in further
expanding the business scope of convenience stores
and improving the economic benefits of convenience
stores. Finally, it realizes the quickness and efficiency
in the management of convenience stores.
In summary, the retail market is undergoing
tremendous transformation and development in
response to changing consumer needs and continuous
technological advances. The rise of small and
medium-sized supermarkets reminds us that
convenience and personalized service have become
important factors in consumer choice. In future
competition, retailers that balance convenience and
science will better cope with the flexible and
changing market and thus succeed.
5 RECOMMENDATIONS AND
OUTLOOK
In MIS, security and efficiency are of paramount
importance. MIS undertakes the important task of
managing and processing corporate information, so it
is necessary to ensure that information is stored
securely and accessed efficiently. And the efficiency
and security of the MIS are closely related to the
database.
In MIS, security is one of the primary
considerations. With the rapid development of
information technology, enterprises not only need to
protect sensitive data such as customer data and
financial information but also face a variety of
security threats from both internal and external
sources, such as data leakage and hacker attacks. A
series of operations for the database can make up for
the shortcomings in this regard to a certain extent. For
example, the database can be backed up from time to
time and recovery functions can be added. The
database is backed up in full at regular intervals, and
the backup data is stored in different geographic
locations or cloud platforms. In this way, even if the
database has a serious failure or data loss, the
company can quickly recover to the previous state
through the backup data, to ensure business
continuity and reliability. Security threats can also be
prevented by recording and monitoring database
