In accessing or searching data by using Query or Join on applications that are connected to a database, the usefulness of the implementation of the data and the process time is important to note. There are many ways that a system management database can do in processing and generating answers to a query. All methods will eventually produce the same answer (output) but they would still have different values, such as the time to respond to data. Some queries that are often used for processing data are Hash Join and Nested Join, both queries have different algorithms but produce the same output. A client-based or network-based application was employed to test both algorithms or queries with running time parameters or the time to respond to data. The test was conducted by connecting the number of tables and the number of rows/records. The result of the study is that the query hash join’s speed in response to small amounts of data is better than the large data in the nested join.

SMS from these various considerations is feasible to use. The level of ownership of cellular phones and affordable costs are considerations that support the adoption of this technology to be widely applied for the application of information system development in the present and in the future.Distance and long time are no longer a problem that can hinder obtaining information about the exam schedule, the SMS received does not come directly from the sender, but comes from the SMS Center. So, before the SMS reaches the recipient, the SMS actually enters the SMS Center first,The PDU contains not only the message, but also a lot of information about the sender. Starting from the sender's number, the sender's SMSC number, the validity time of the SMS, and so on. Everything is built in the form of hexadecimal numbers. SMS-based student exam scheduling using AT Command GSM which is used as a command in communication with the serial port. Scheduling with the AT command technique is very effective as information for students.
