PENGEMBANGAN BASIS DATA SISTEM INFORMASI AKADEMIK PERGURUAN TINGGI BERBASIS SCHEMA MATCHING LINGUISTIC, CONSTRAINT DAN INSTANCE

2022 · Article · Artikel Penelitian dan Pengabdian

Universities currently need information systems to support their activities. Bumigora University is one of the universities that implements information systems such as Siska and E-Learning. Both the system and the database of the two systems are still independent. So that the same data input is still happening on different systems. Based on these problems, it is necessary to develop a database that can connect information from Siska and E-Learning. The method used in this research is Schema Matching. The Schema Matching method used is the Linguistic, Constraint, and Instance Schema Matching method. The results showed that there were several table pairs with true positive and false positive values so that the precision, recall, and F-measure values obtained were 0.8, 1, and 0.89. The F-measure value obtained is 0.89 which is greater than 0.5 so it can be said that the scheme matching process is running quite well.

Taletan Ijo is an online shop that sells fruit seeds. In carrying out its business processes, he utilizes a sales information system. The system is used to manage sales data. If the data is not used, it will lead to accumulation of data but lack of information. Taletan ijo uses the manual method in its product marketing strategy so that the strategy used is not quite right. Stored sales transaction data can be used as a reference in making marketing strategies such as making product sales packages. This study uses data mining methods, namely associations with a priori algorithms to process transaction data into information that can help support decisions in determining marketing strategies. The results of the study show that the lift ratio test results obtained are 3.2 which indicates that the value is valid with a minimum number of transactions of 10 and a confidence value of 80.

University is one of the agencies that use information technology to support various business processes. University requires data integration between the systems so that the data available in one system can be used in other systems to support data management.In forwarding data integration there are several obstacles that occur one of the causes is schema heterogeneity used by each information system. linguistic method is one of the schema matching methods used to overcome the problem of schema heterogeneityBased on the analysis of database schemes with the linguistic method, the values of precision, recall and f measure are 0.75. This value indicates that the application of the matching schema has been quite good. But there are still some of the same data between the schemes so that the integration of the data owned is not maximal. So that optimization is still needed to maximize the data integration
