[Data structure] stores a single-chain table sequentially, and stores a single-chain data structure. Data StructureSequential storage of Single-Chain tables There is nothing to worry about. Let's review the data structures we 've learned before and write a bit of fun. There's not much to talk about the theory, and there's a lot of online searches; It is important to master the idea of this data structure.

same time, you do not have to modify the query statement at all. Of course, this assumes that the metadata for your data store is compatible with the data structure. Different data stores expose or infer meta data in different ways. The JDBC database typically exposes metadata through the JDBC metadata API. File formats, such as CSV and Excel tables, are not explicitly defined, and you can usually read the first line of the file to get their metadat

If using MyISAM, the merge engine can greatly speed up the development of the application, as long as they do some select count (*) operations on the merge table, which is ideal for business tables of a certain type (such as logs, survey statistics) of a large project with a total of about hundreds of millions of. Of course, InnoDB is not absolutely not, with business projects
