Abstract

In a certain period of time, most educational institutions produce data with a huge capacity from their operational activities. From those data will appear the need to obtain certain information which is useful as a material of performance evaluation or even as a material of management decision. Data warehouse is one of solutions of these needs. When the capacity and complexity of data warehouse has been increasing, then full extract technique in Extract Transform Loading (ETL) process becomes inadequate, even in others case this technique can not be applied, because this technique causes a large cost. Delta extraction can be one of the solutions of this problem because the process is to extract only the data which has been changing in ETL process. Delta extraction technique will be tested on MySQL DBMS using historical table and trigger. From the result of load test, it can be concluded that trigger gives the load to its parent table, but the waiting time that is required is still tolerable.

Abstract

In the undergraduate program to take the final exam, a student is assigned to make the final task in the form of a thesis. In making this thesis a student first determine the topic to find the problem to be lifted. Problems that exist, final year students still difficult to determine the topic of thesis in the final project. Therefore some lecturers provide certain kinds of topics according to their field of expertise which are then published on the website. That way the student must often visit the website to see the latest topics that have been published by lecturers. And students also have to search for topics one by one according to the topic he wants. This is not efficient enough if students should frequently visit the website and search for topics one by one according to the topic to be discussed considering not knowing the time of publication of the latest thesis topic and not classified topic of thesis based on topic. With the mobile app using the Publish / Subscribe method the student will be more efficient in getting the latest thesis topic information and according to the desired topic. Based on the results of functional and non functional tests concluded to run as expected. Results from functional testing with 100% validation rate. While the result of non-functional testing is the time required to send messages from publisher to subscriber using QoS 0, QoS 1, QoS 2 is 0.490 seconds , 0.561 seconds, 0.720 seconds.
