Business Logic Use Cases

You need business logic to:

• Implement complex calculations or logic. Java code provides additional programming safety, is easier to maintain on the long run, and is faster than Java Script.
• Perform calculations without loss of precision. You can use the BigDecimal object to perform such calculations.
• Handle large data sets. Browsers cannot handle even thousands of records reliably, but Java code can handle millions of records.
• Execute database-specific SQL queries. Web Central Java API can generate SQL queries that work on all databases, and can parse/format database values.
• Handle sensitive data such as passwords or financial records. Server-side code and data are well-protected from unauthorized access, while browser code and data can be easily hacked.

You do not need business logic implemented in Java, and can use Java Script to:

• Perform simple data transactions , such as updating or creating a data record.
• Process data for display purposes , for example highlight work requests in the grid based on their statuses.
