Abstract

Currently, there is still a lot of writing / recording of data (drug) on conventional pharmacies done. One of them is the pharmacy Sammulia Medika. Medication data processing at pharmacy Sammulia Medika still use manual recording method, that is all data recorded in a book or archive, for that needed by drug data search application.The data search algorithm used is Rabin-Karp algorithm used to perform string searching process by using k-gram process for word distribution, and using hashing function to find pattern in text string and similarity that is similarity between words searched with existing word.Based on the results of the test, Rabin-Karp algorithm can be implemented in drug data search application to match word with similarity value up to 100%.Keywords—Drug Data, String Search, Rabin-Karp Algorithm. DOI : 10.5281/zenodo.1402396

Abstract

Halu Oleo University is building an integrated university database with a centralized database system. One of the data that is integrated is the alumni database. The alumni database can be designed using a relational database system. According to [1] the relational database can be an alternative because it has the advantage of storage capacity. Some basic mathematical theories such as set operations can be used to design and develop a database. Furthermore, the agreement function can be used to retrieve information from a database. In this research will be done on the database design alumni of Halu Oleo University by applying the approach of set operation and aggregation function.Keywords­— Set Operation, Aggregation Function, Alumni DatabaseDOI : 10.5281/zenodo.1343370
