How to choose the right database? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

How to choose the right database?

First of all, select the appropriate database type according to the business scenario, such as hierarchical database, network database and relational database; finally, according to the business scenario, read and write performance and product characteristics and advantages, select the corresponding database products.

Hierarchical database

Hierarchical model database system is the earliest database system developed successfully, and the most successful model of this kind of database is IMS.

The full name of IMS is Information Management System, which was successfully developed by IBM Company.

IMS was put into operation in 1969, and the earliest versions are IMS/360-1 and IMS/360-2. The more recent version is IMS/VS DL/1, which runs under the support of the operating system DOS/VS (Disk Operation System/Virtual Storage).

Network database

The network database must have the characteristics of real-time and high efficiency, it should not only be able to handle the data operations of multiple terminals at the same time in parallel, but also be able to resist the invasion of hackers and viruses on the network.

The network database technology is very important for the network management system, because for most systems, the database is the key to the data record. without the database, the normal operation of the management system is impossible. The network management system needs network database technology to support and maintain, in order to operate more safely, the network database generally enters into a contract with firewall tools. Through the network firewall to judge and resist bad access users, customers who pay special attention to data security are more inclined to choose high-price network server hosts to obtain virus protection systems and network firewall systems with more quality assurance, so as to ensure the security of their own data.

Relational database

A relational database is a database based on a relational database model, which deals with the data in the database with the help of concepts and methods such as set algebra. at the same time, it is also a group of tables with formal description. The essence of this form of table is to load a special collection of data items. The data in these tables can be accessed or reconvened in many different ways without the need to reorganize database tables. The definition of a relational database results in a table of metadata or a formal description of tables, columns, ranges, and constraints. Each table (sometimes referred to as a relationship) contains one or more types of data represented by columns. Each row contains a unique data entity, which is the category defined by the column. When creating a relational database, you can define the range of possible values of a data column and further constraints that may be applied to that data value. The SQL language is the interface between standard users and applications to relational databases. Its advantage is that it is easy to expand, and after the initial database creation, a new data type can be added without the need to modify all existing applications. The mainstream relational databases are oracle, db2, sqlserver, sybase, mysql and so on.

The answer to the question on how to choose the appropriate database is shared here. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
