My current task involves fetching data from a server and showcasing it through GWT on the client side.
The use of GWT is flexible - it can be swapped out for Ajax calls or transformed into a standalone application rather than just a web app.
One dilemma I face is deciding whether to sort the data on the server or utilize JavaScript on the client side to sort the data before displaying it. What would be the ideal approach?
There are advantages and disadvantages to each approach:
It is highly recommended to perform the sorting on the server for several reasons:
Considering that some users may have limited resources, such as those accessing the application from a mobile device, it is more efficient to offload the sorting process to the server.
While there are established methods like using SQL ORDER BY clause for server-side sorting, implementing client-side sorting requires custom routines which can be time-consuming and complex.
It varies... :)
From an architectural perspective, selecting the best approach involves determining the desired attributes within your system and weighing the pros and cons of different design choices. Without a deeper understanding of your system, it is challenging to provide advice beyond this point.
It is essential to avoid making blanket statements like "it is always faster to sort on the server than on the client." I encountered a situation where I needed to retrieve numerous records sorted by the combination of last name and first name, both of which were not indexed. As expected, sorting concatenated strings is a challenging task for databases that prioritize numbers or indexed fields. Surprisingly, in this case, sorting on the client turned out to be quicker. If only I had the authority to optimize the database, I would have considered adding a function index in Oracle for these two fields.
The lesson learned here is never assume anything and instead analyze your application to determine the most effective approach for your specific scenario.
