非关系型数据库：灵活存储与高效查询，探索数据管理的未来 头豹词条报告系列

Investment Rating - The report does not explicitly provide an investment rating for the NoSQL database industry Core Insights - The NoSQL database industry has rapidly emerged due to its ability to handle large-scale, distributed datasets, particularly unstructured data, changing the data management landscape. The market size grew from 10.416 billion RMB in 2019 to 19 billion RMB in 2023, with a compound annual growth rate (CAGR) of 16.21%. However, it is expected to decline from 19.026 billion RMB in 2024 to 9.226 billion RMB by 2028, with a projected CAGR of -16.55% [5][30][31]. Industry Definition - NoSQL databases refer to a range of data storage and retrieval solutions that differ from traditional relational database management systems, designed to handle large-scale, distributed datasets, especially those unsuitable for traditional tabular structures. The rise of cloud computing, big data analytics, mobile internet, and IoT technologies has led to widespread adoption of NoSQL databases [6]. Industry Classification - The NoSQL database industry can be classified into several categories: - Document databases store data in flexible document formats (e.g., JSON, BSON, XML), suitable for semi-structured or unstructured data [7]. - Graph databases are designed for storing and querying complex relational data, ideal for social network analysis and fraud detection [8]. - Key-value databases store data as key-value pairs, known for their high read/write performance and flexibility [9]. - Columnar databases optimize query performance and storage efficiency by storing data by columns rather than rows [10]. Industry Characteristics - The NoSQL database industry is characterized by high technical barriers, a mature supply chain, and intense competition [11]. Technical Barriers - The technical barriers in the NoSQL database industry are high due to the complexity of data models and optimization algorithms required to handle large-scale, distributed datasets [12][13]. Supply Chain Maturity - The supply chain for the NoSQL database industry is mature, encompassing hardware infrastructure to software toolchains, with cloud service platforms providing robust support for deploying and managing large-scale distributed systems [14]. Competitive Landscape - The competition in the NoSQL database industry is fierce, with numerous open-source projects and strong commercial products, leading to rapid technological advancements and increased service quality [15]. Development History - The NoSQL database industry has evolved through four stages: - Emergence (1998-2004), where it began to challenge traditional relational databases - Initiation (2005-2010), as enterprises recognized the need for efficient data management - Rapid Growth (2011-2019), with graph databases gaining traction for complex data relationships - Maturity (2020-present), where reliability and applicability in enterprise settings have been validated [16]. Industry Chain Analysis - The NoSQL database industry chain consists of upstream (hardware and technology support), midstream (database system development and services), and downstream (application and end-user segments) [21]. Market Size Overview - The market size of the NoSQL database industry increased from 10.416 billion RMB in 2019 to 19 billion RMB in 2023, with a CAGR of 16.21%. It is projected to decline to 9.226 billion RMB by 2028, with a CAGR of -16.55% [30]. Future Market Changes - The demand for pure NoSQL databases is expected to decrease as traditional relational databases enhance their support for non-relational data, reducing the need for dedicated NoSQL solutions [33]. Competitive Landscape Overview - The Chinese NoSQL database industry exhibits high market concentration, with leading companies such as Huawei Cloud, Tencent Cloud, and Alibaba Cloud in the first tier, followed by companies like Nanda General and Oracle in the second tier [37].
