Based on the Equation 4 and 5, the mapping can be denoted as ${tex`(v_1 \times v_2 \times ... \times v_a), (v_{a+1} \times ... \times v_{a+b}) \rightarrow (v_{a+b+1} + ... + v_{a+b+c})`}. In particular, the ${tex`a`} and ${tex`b`} cannot both be zero and are usually not very large (${tex`< 5`}) in practice to avoid tables with too many empty cells like Fig. 6 and 7. Therefore, the worst-case time complexity is ${tex`\Omega(N^3M)`} for cross-tabulation (${tex`a > 0`}, ${tex`b > 0`}, and ${tex`c = 1`}) and is ${tex`\Omega(cN^2M)`} for other tables (either ${tex`a = 0`} or ${tex`b = 0`}, and ${tex`c \geq 1`}). We analyze the complexity based on the two phases of the declarative mapping approach: _extract_ data variables and relations and _map_ variables to table channels. - The extract stage scans the input data such that the complexity is ${tex`O(N \times M)`}. - The map stage derives and maps variables to table channels, and the worst-case time complexity is ${tex`O(cN^{1+a+b}M)`}: - The worst-case time complexity of variable derivations is ${tex`O(N^2)`}. Specifically, the functions of variable derivation handles one-dimensional data variables comprising a set of data values, the complexity of most derivation functions is ${tex`O(N)`} except _sort_ (${tex`O(N^2)`}). In addition, the output variables of these functions have at most ${tex`N`} values. One exception is the _unnest_ function, which unnests a variable of nested objects (e.g., array and set) and produces a variable that has more than ${tex`N`} values. Moreover, the unnest function can be applied multiple times on multiple nested objects, and its complexity is hard to determine. Hence, we exclude the unnest function in the subsequent analysis. - Since the proposed approach enumerates the values of the variables mapped to the row and column channels, the worst-case time complexity of mapping variables to the row and column channels is ${tex`O(N^a) (a > b)`} or ${tex`O(N^b) (a \leq b)`}. - The worst-case time complexity of mapping variables to the cell channel is ${tex`O(cN^{1+a+b}M)`}. Specifically, the proposed approach queries the values of variables mapped to the cell channel. On the one hand, the queries require iterating over the input data, and the worst-case time complexity is ${tex`O(N \times M)`}. On the other hand, the cell channel comprises at most ${tex`cN^{a+b}`} cells (${tex`N^{a+b}`} cells for cross-tabulations where ${tex`c = 1`}, and ${tex`cN^a`} or ${tex`cN^b`} cells for other tables where ${tex`b = 0`} or ${tex`a = 0`}). We found that the major bottleneck is mainly from the queries, which takes ${tex`O(N \times M)`} time in each cell in the cell channel. Meanwhile, the traditional data operators fix the operations of cells and only take ${`O(1)`} on each cell. We plan to construct indexes between variables to reduce the complexity of these queries to close to ${`O(1)`} in the future. Since these queries frequently query a variable value by multiple other variables, data cube ${hyperlink("ref1", "[2]")} and related techniques may be appropriate. With the indexes, the worst-case time complexity will be reduced to ${tex`O(cN^{a+b})`}, which is comparable to traditional operators. In addition, the declarative mapping approach will prevent unnecessary computation and operation by skipping the intermediate tables of operation sequence and directly computing the resulting table.3e:T562,The current version of Rigel system supports two input data formats: **JSON** and **CSV**. ### JSON A sample input in JSON format is given as follows. The *name* field represents the name of the input table. The *values* field should be an array indicating records of the table. Each element should be an object corresponding to a record. ```json { "name": "crime", "values": [ { "state": "Alabama", "year": 2004, "crime": 4029.3 }, { "state": "Alabama", "year": 2005, "crime": 3900 }, { "state": "Alaska", "crime": 3370.9, "year": 2004 }, { "state": "Alaska", "crime": 3615, "year": 2005 } ] } ``` ### CSV A sample input in CSV format is given as follows.
