| 4 | Editing index library | PUT editing index library |
| 5 | Delete index library | DELETE deletion index repository |
| 6 | Querying all table names in a given index repository | GET query of all table names in a given index repository |
Optionally, the index database management module includes a spatial grid index model, a large data index file table, and a large non-relational data index table;
the spatial grid index model is used for constructing a spatial grid index by utilizing a subdivision index technology and realizing the association of data and a space-time subdivision grid;
spatial grid index model: by utilizing a subdivision index technology, a cross-domain and multi-scale spatial grid index model which is convenient for data storage and maintenance is constructed on the basis of a data uniform organization code system, the association of data and global space-time subdivision grids is realized, technical support is provided for data organization and association indexes, and the cross-database association retrieval efficiency of the data is improved.
The data index file large table is used for establishing a key value database by taking a grid index code as a main key;
data index file big table: and establishing a Key-Value database (Key-Value Store DB) by taking the grid index code as a Primary Key (Primary Key). Because the key-value database organizes data in a form similar to a table, the key-value database organizes the data into a multidimensional sparse matrix which is a huge table logically, and the index database model is simply called as a large table of a data index file.
