Column Types in Pega Local Storage
Pega allows developers to focus on their primary tasks from the get go. Already during the Direct Capture Objective (DCO) sessions we can define our Data Models in PRPC. But what is actually created in this PegaDATA database when we add a Data Type with Local Storage? Let´s investigate what happens when we create a simple Car class named WCR-Data-Car. In the above example we have created a new data type Car for the WCR application in the usual Data- hierarchy and added several properties (one for each available data type). By default PRPC will maintain records as BLOBs (in pr_other). However we now choose to "Create a local source" to have the engine generate a separate table to see what the column types are. On the Advanced tab we can inspect that the new table is named pr_WCR_Data_Car. Note: If there is already a table with that name PRPC will generate some unique suffix. Navigating to the wizard at DesignerStudio > System > Database > Modify Schema allows us to list the actual data types for each of the Car´s properties.
|Property Name||Data Type||Column Type (Size)|
|CO Per Mile||Double||NUMERIC(38)|
|Last Fuel||Date Time||TIMESTAMP(29)|
|Alarm||Time Of Day||VARCHAR(6)|
|Diesel Engine||True / False||VARCHAR(5)|
