Layout Builder feature helps you to upload a sample or an original source (JSON downloaded from Adv. Database layout manage page) file to define the layout. By default, this feature remains disabled in the product. You need to enable this feature before you start working on this. You can create an Advanced Database Layout using Layout Builder in Adeptia Connect. Layout Builder helps you create an Advanced Database Layout by importing a JSON (downloaded from Advanced Database Layout manage page) file or by using a database table. By default, Layout Builder remains disabled in the product – you need to enable it before you can create a layout.
Steps to create Advanced Database Layout:
- Click Configure > LAYOUTS > Advanced Database.
- Click Create Advanced Database Layout.
- On the Create Layout screen, select the Layout Builder option from the drop-down list of option in the Select Layout UI Type field.

Select
the Schema Version checkboxthe Auto increment Key Support checkbox if required. This feature is used when the parent table's Auto Increment column is referenced in the child table. Enabling this checkbox automatically populates the value in the child table's foreign key column with the Auto increment column's value from the parent table.
- Select schema version 2.0 checkbox if you want to create the layout without the name dependency.
Select the Filter Invalid XML Characters checkbox to filter out invalid XML characters (if any) in the input data
Info In case, the input data contains some characters that are invalid in XML, then this may result in the mapping getting aborted. Select the Query Batch Update checkbox to enable the query batch update, and enter the batch size in the Query Batch Size field.
Info Enabling the Query Batch Update checkbox leads to database updation in batches as per the positive value set in the Query
Batch Size field.
For example, setting a value '10' in the Query
Batch Size field will group 10 separate statements and submit them as a single batch. However setting the value to '0' will disable the batch execution and execution of every statement will occur simultaneously.
You can achieve performance optimization by using batch update. The advantage of batch update is to reduce the network calls to the database by not executing every single SQL query when they are raised. By using this feature, you can send multiple queries to the database in a single instant and thereby reducing the number of JDBC calls and improving performance.
This feature is available for the Insert and Update operation only.Select the Use Commit Count checkbox to enable the Commit Count field, and enter the number of statements that you want to commit to the database in a single instance in a field.
Info When you set the commit count value to a positive integer value then the layout starts and commits a batch of transaction as per the number in the Commit Count text box. This helps in reducing the network traffic and in turn increases network performance. This is called as batch transaction.
Select the Handle Null/Empty Element(s) checkbox to handle Null or Empty elements.
Select the Use Parent/Child DataSet. This field works in tandem with Commit Count.
- If this checkbox and Commit Count is enabled then this will call commit when parent record (including its hierarchy) count is equal to commit count. In case of any error rollback will not happen
- If this checkbox is enabled and Commit Count is disabled then this will call commit count for every record including its hierarchy. In case of any error in the record including its hierarchy, the complete record will be rolled back.
- If this checkbox is disabled and Commit Count is enabled then this will call commit when count of its parent and its child record is equal to commit count. In case of any error rollback will not happen.
- Click Save Layout to save the Advanced Database Layout.
