Analyze The Problem
If we work as a team, this work is actually for Systems Analyst. We must analyze the problems that happen in our company mangement systems. Find every problems that exist and try to solve it. After we found the problems, we must specify everything that we need to solve this problem. We must define the technology that we will use. Define what database system we must use. Define the flows from the systems. We can define it by create flowcharts or diagrams.
Database Design
After analyze the problem, now we know what technology that we will use. For database, we can choose what we will use. Is mySQL, Firebird, Oracle, or another database system. Make a list for tables that we need for systems. For example, if we want to make Payroll system, define all data that we need for this system. Specify the relation between tables if it needed.
