With big data and complex processing, some process may become slow. We will see how to take full advantage of 4D’s toolbox and how to use different approaches and algorithms to deal with big tasks. Some techniques that we will study involve: hash coding, dichotomy on files, distributed processing, handling “group by” on large data, pre processing, batch processing, bit fields, usage of different index types, reorganize the database structure to improve speed...
