Oracle Data Replication Technology in Packaging Enterprises (I)

[Abstract] The article introduces the concept of data replication, and describes the application of oracle data replication technology in digital anti-counterfeiting system for packaging companies, and gives corresponding application examples.
Keywords: packaging; digital anti-counterfeiting; data replication; data consistency; snapshots With the development of computer technology, many packaging companies to establish a digital anti-counterfeiting system to verify the authenticity of products produced by the company, so that consumers can buy high-quality The authenticity. However, if there is data failure, it will seriously affect the normal operation of the daily business, and it will not respond to the authenticity verification request of the products that consumers may send at any time, which will seriously damage the corporate image; the data replication technology introduced in the text can prevent data. Failure, but also to solve the data consistency, reliability, improve the speed of data query.
1 Introduction to Digital Anti-counterfeiting System The digital anti-counterfeiting system of a packaging company consists of two parts, a “digital anti-counterfeiting label generation system” and an “inquiry system”. The former consists of a dedicated server, using number theory and permutation and combination techniques, to create a unique, non-repeatable, unlawful, lengthless anti-counterfeiting code for each piece of network access products of the enterprise and store it in a dedicated database. After the products are produced, anti-counterfeiting codes are printed on the packaging of each product on the network. This anti-counterfeiting code corresponds to the anti-counterfeit code in the database.
"Inquiry System" is a network system specially composed of anti-counterfeiting background database, computer terminal, Internet, telephone network, and user's short message service. If consumers want to know the authenticity of their products, they can accurately and timely identify the authenticity of the purchased products in several ways: call the digital anti-counterfeiting system; the anti-counterfeiting code will be sent to the business-designated phone through SMS. Phone printed on the package). Connect to Internet via a computer terminal.

As can be seen from Figure 1, the availability of the back-end database and its speed has become the key to the entire anti-counterfeiting network, in order to ensure high availability of data and data corruption, improve query response time, increase a database server, and existing The database runs synchronously and uses oracle advanced replication technology to replicate data between the two databases.
