Partial Data Sandbox

With Winter'14, salesforce has introduced a new sandbox type 'Partial Data Sandbox'. It will be fourth type of sandbox besides Developer Sandbox, Developer Pro Sandbox and Full Sandbox.

Partial Data sandboxes include all of your organization’s metadata and add a selected amount of your production organization's data that you define using a sandbox template. A Partial Data sandbox is a Developer sandbox plus the data you define in a sandbox template. It includes the reports, dashboards, price books, products, apps, and customizations under Setup (including all of your metadata). Additionally, as defined by your sandbox template, Partial Data sandboxes can include your organization's standard and custom object records, documents, and attachments up to 5 GB of data and a maximum of 10,000 records per selected object. A Partial Data sandbox is smaller than a Full sandbox and has a shorter refresh interval. You can refresh a Partial Data sandbox every 5 days.

For a Partial Data Sandbox first you need to create Sandbox Template. For creating a sandbox template please see https://help.salesforce.com/HTViewHelpDoc?id=data_sandbox_templates.htm&language=en_US

Mashup Integration in Salesforce

During preparation for TA certification exam, I came across a word Mashup for integration a number of times. I explored about it and below is description:- Mashups, sometimes called “composites,” are hybrid applications created by bringing together several data sources and Web services to create a new application or to add value to an existing application. Behind the scenes, mashups may require different levels of integration, depending on whether the mashed-up data is only meant to be viewed, whether it can be edited, and whether data is actually transferred between systems. There are three types of mashup:- Client Presentation Mashup - In this type of mashup the integration takes place strictly at the visual level. It makes possible to view data from two or more applications in a browser,  without actually moving data between the applications. Example - Google Maps. Client Service Mashup - As mashups evolve, they are becoming more complex and sophisticated. Client...

ReadOnly Annotation

Use Case:- You want to show up to 10000 record on single VF page. Count of records based upon some business requirement where number of records could go up to 1 million. So far, it was not possible to achieve above in VF page because of following limitations:- The maximum number of items in a collection that can be iterated over using components such as <apex:dataTable> , <apex:dataList> , and <apex:repeat> is 1000. Normally, queries for a single Visualforce page request may not retrieve more than 50,000 rows. Solution:- But with API version 23.0 , salesforce has introduced ' ReadOnly ' annotation which has following functionality/restriction:- The @ReadOnly annotation allows you to perform unrestricted queries against the Force.comdatabase. All other limits still apply. It's important to note that this annotation, while removing the limit of the number of returned rows for a request, blocks you from performing the following operations ...

Grant Access Using Hierarchies

Problem There is a custom object say 'XYZ' and OWD for this is set to ' Private ', which means record of this can be seen by only owner and users above in role-hierarchy and territory. However, to share this with other user, we can manually share it. The problem is that I don't want other users, who are above in role-hierarchy and territory of the user with whom record has shared, can see it. Solution We can un-check ' Grant Access Using Hierarchies ' check box for object 'XYZ' on 'Sharing Settings' page. We can go to Setup >> Security Controls >> Sharing Settings and click on ' Edit ' button. On the edit page, we can un-check ' Grant Access Using Hierarchies ' for required object.  Major uses of 'Grant Access Using Hierarchies' are:- If you disable the Grant Access Using Hierarchies option, sharing with a role or territory and subordinates only shares with the users directly asso...
