MongoDB: Ideal for enterprise-level report development?

Recently, a development team has planned to use Python and MongoDB to build prototype systems, but is hesitant about database selection. Their project requirements include rapid iteration, multi-field and complex business scenarios, so they tend to be flexible with MongoDB. However, they are concerned about MongoDB's performance and efficiency when handling complex association queries such as generating enterprise reports.

MongoDB does have limitations in handling complex association queries. Unlike relational databases such as MySQL, MongoDB does not support association operations and subqueries across collections. This means that when a report needs to associate multiple data sets, MongoDB may not be able to complete the query directly and efficiently. In this case, developers need to write more complex code to simulate association operations, which may reduce query efficiency and increase development difficulty. If the report requires frequent large number of correlation queries and requires high query performance, then relational databases such as MySQL may be more suitable.

However, MongoDB is not without its advantages. It excels in handling unstructured data, flexible queries, and distributed systems. If the data structure is more flexible, the fields change frequently, or the application needs to deal with high concurrency and massive data queries, then the advantages of MongoDB will be fully reflected. For example, for some analytical reports, if only aggregate statistics are needed without complex correlation queries, MongoDB's aggregation pipeline function can meet the needs.

Ultimately, choosing MongoDB or MySQL, or even other databases depends on the specific business needs and data characteristics. It is recommended to conduct prototype development and performance testing for specific business scenarios before the final decision, evaluate the performance performance of different databases, and select the optimal solution.
