You also have to specify column types in a relational system, so you might find yourself constrained by, say, the length of the address field. 284. Immediately after the selection and programming environments from the relational database to achieve the two-pronged approach on how to develop a bookstore information management system. 285. Similar to relational systems, RTQP provides an algorithm for saving main memory space under the MMDB, and a query optimization integrated the rules in RTDBs and the GAs. 286. A relational database comprises a set of well structured flat file. 287. The computing result of the model indicates that the grey relational analysis can ensure more practical results. 288.
