I am new to Pega and started with PDN, i would like to know how is the data stored in Pega, what is the database it uses and the language used to retrive the data .Do application developes need access to the database.
For storing the data in the pega we have the data tables in pega.It is using the pega data table by default. But we can create the data table by our own with the needed properties. We dont need any other languages to retrieve the data from tables.Pega made it very simple by using the data pages, report definitions and the activities.
In pega previous versions the data tabels are created using the designer studio but in the lastest versions of pega the data tabels are created directly from the data icon and will define the data table name first and you need to give properties which you want in the table. After that you can directly give the data by using the records tab.We can also select the primary key from that tab for the data table.
Other feature is pega by default creates the datapages for your data table. You cand find them in the sources tab.
Note: The datapages will only create when you first access the datatable.
