Data Manipulation
Separation of code and data.
Avoid hard-coded html in the rules, instead use tag replacement techniques or templating techniques (custom templating, template engines, frameworks or CMS’s) that help separate code (business logic) from data (html output).
This helps web designers to focus only on the code relevant to the user interface and not any business logic.
Custom templating should be designed in such a way that it is directly related to the data output
with the use of “if”, “while”, “for”, “foreach”, “switch” control structures
and it should be readable.
The selected templating technique should be consistent throughout a solution, avoiding confusion.
Two tag replacement techniques are detailed in the Appendix A. For more advanced options, like the use of control structures, a templating engine should be used.
Content Files
Include static files, such as js/css libraries in the “Content Files” node.
File and folder organization should be agreed upon by the team, and remain easy to understand and structured.
Data Files
Include data files, such as html, CSV files in the “Data Files” node. A benefit of reading from “Data Files” is that it will be memory cached, and you can update it without redeploying all rule sets, but simply by deploying the data file on its own.
Data Sets
For smaller applications Data Sets are a preferred way to store data, instead of using SQL statements. Data Sets are incredibly flexible and do not require modifications to the schema for every new field or feature.
See the Data Set rules to study an example.
Data Sets are more than adequate for anything up to about 100,000 elements and they offer flexible “key-on-anyfield” and “add a new field any time you like without stopping” capabilities.
Data Input
Custom functions in the Tomorrow Software console can be used as an interface for corporate end-users who have been assigned the role of application/user data maintenance, such as localization data, selection list data, user data, csv files or databases.
User access to desired custom functions can be granted to users through the Tomorrow Software console, by a Tomorrow Software administrator.
Memory Considerations
Consider increasing maximum memory usage when reading from large files that their content needs to be saved to a variable for further processing (i.e., “File Reader” rule), by changing java startup properties in your Tomorrow.bat file. If the file just needs to be forwarded to a http client, then use the “HTTP File Response” rule.
