【Abstract】 With the gradual popularization and application of domestic databases in the domestic financial industry, more and more systems in the construction of financial industry informatization need to use centralized or distributed domestic databases to replace the original Oracle database. This paper mainly focuses on the storage architecture of domestic databases and Analyze and explain from the perspective of scenario application, and provide suggestions for the selection of domestic database storage applications.
1. The market structure, technical background and development pattern of domestic databases
1.1 The development of domestic databases
Database (DB for short) is a warehouse that organizes, stores and manages data according to the data structure. The database management system (DBMS for short) is used to establish, use, manipulate and manage the database, and together with the database, it forms a database system. The database calls the underlying hardware resources downwards and supports the application business upwards. It is one of the three basic software and an important basis for the realization of computer functions. The database has developed a variety of technical paths. According to the data model, business load characteristics, deployment method, and adaptive hardware architecture, databases can be divided into various types. The data model determines the logical structure of the database and the storage, organization and operation of data, and is the most important element.
From a global perspective, the origin of database development dates back to the 1960s. In the 1970s, the relational database model appeared for the first time. After it came out, it entered the public eye because of its high ability to describe the logical model, such as IBM's DB2 and Oracle's Oracle. At the end of the 20th century, traditional relational databases were widely used, and commercial databases such as Oracle and IBM also developed vigorously. In China, the products of four traditional vendors, Oracle, IBM, Microsoft, and SAP, once occupied more than 90% of the domestic commercial database market. Currently, Oracle dominates the Chinese database market.
In order to achieve safety and reliability in terms of data, since the 1990s, many large and small enterprises in our country have begun to set foot in the field of domestic databases. Although the development of database manufacturers in my country was difficult in the early days, they have also achieved considerable results: China has the first generation of prototype databases, and has also emerged such as Neusoft Openbase, Chinasoft Cobase and Huake D
