Creating Multidimensional Arrays on the Application Level
| In this section, you learn how multidimensional arrays can be generated on the application level. Depending on the programming language you choose, the processes might differ , but there are basic algorithms and ways of processing huge amounts of data. Processing data on the application level usually starts with reading data from the database. During this step, the amount of data has to be reduced and a suitable data format has to be chosen . The second step is to create an array or to allocate some space in memory where the result of the process will be stored. The memory allocated must contain a field for all combinations of data that can occur in the result. You will find it useful to know which values can occur in the output so that the right amount of memory can be allocated and you know where to insert the data at runtime. If you don't know which values the output contains, the process is much more complicated.
