Team selection  required for any  project get developed in salesforce

The best people to staff on Force.com projects might already work at your company. Projects do not require brand-new teams staffed with Force.com experts.With the majority of the platform based in mature technology such as relational databases and Web-development,adapting existing teams can be a straightforward task.

Here are some examples of traditional software development roles and how they can
contribute to a Force.com project: 

 Business Analyst

Substantial Force.com applications can be built entirely by configuration, no computer
science background or coding skills required. Salesforce refers to this as
“clicks, not code.” Business analysts who are proficient with Microsoft Excel and its
macro language, or small-scale databases like Microsoft Access and FileMaker Pro,

can get hands-on with the Force.com data model, validation rules,workflows,
approval rules, and page layouts.

Data Modeler

A data model forms the core of a Force.com application. Data modelers can use
their existing Entity-Relationship tools and techniques to design the data layer,
with some deltas to account for Force.com-specific idiosyncrasies. Rather than
scripts of DDL statements, their work output is Force.com’s metadata XML or
manual configuration of the data objects. Data modelers can also design reports and
report types, which define data domains available to business users to build their
own reports.

Database Administrator

Many traditional DBA tasks are obsolete in Force.com because there is no physical
database to build, monitor, and tune. But a DBA still has plenty of work to do in
planning and implementing the Force.com object model.There are objects to
define or permissions to configure, and the challenges of data transformation and
migration are still as relevant in Force.com as in any database-backed system. Database Developer
The design of Force.com’s programming language,Apex, has clearly been inspired
by stored procedure languages like T-SQL and PL/SQL. Existing database developers
can adapt their skills to writing Apex code, particularly when it requires detailed
work on the data like triggers.

 Object-Oriented Analysis and Design Specialist

Force.com includes an object-oriented language, and persistent data is represented
as objects.With all of these objects floating around, people with skills in traditional
techniques like Unified Modeling Language (UML) are valuable to have on your
project team. Larger applications benefit from a well-designed object model, and as
in any language, designing before writing Apex code can be a real timesaver.

 User Interface Designer

Force.com supports modernWeb standards for creating usable, flexible, and maintainable
UIs. UI designers can help by building screen mock-ups, page layouts, and
the static portions ofVisualforce pages to serve as templates and assets for developers.

Web Developer

Developers who have built Web applications can quickly learn enough Apex and
Visualforce and build similar applications on Force.com, typically with much less
effort. Skills in HTML, CSS, JavaScript, or Adobe Flex are needed to build custom
Force.com user interfaces.

4GL Developer

Developers proficient in fourth-generation languages such as Java, C#.NET, and
PHP usually have no problem picking up Apex code. It has the same core syntax as
Java, without the Java-specific libraries and frameworks. 

Integration Specialist

Force.com is a producer and consumer of Web services and supports REST as well
as any integration strategy based on HTTP.An integration expert can design the
interaction between systems, define the remote operations, and implement them
using Force.com or a specialized integration product.

 Quality Assurance Engineer

Testing is a critical part of any software project, and on Force.com testing is mandatory
before code is deployed to production.A QA engineer can write automated
unit tests in Apex and test plans for security and integration testing. Standard tools
like Selenium can be used to automate UI testing.

 Operations Specialist

Although there are no servers or operating systems to manage, larger deployments
of Force.com can involve integration with on-premise systems. Single Sign-On
(SSO) integration and data migration are two common examples. Operations
experts can help in this area, as well as with application deployment and Force.com
administration tasks such as user maintenance.

Validation for Alphanumeric

<apex:inputField value="{!XXX}"  onkeypress="return checkInput(this);"       />



function checkInput(txt) {
    if (/\W/test(txt.value)) {
        alert("Please enter alphanumerics only");
        return false;
    }
        return true;
    }
   

WORKFLOWS IN SALESFORCE

Workflows:

Each workflow rule consists of:

• Criteria that determine when Salesforce executes the workflow rule. Any change that causes a record to match this criteria can trigger the workflow rule—even changes to hidden fields.
• Immediate actions to take when the workflow rule executes. For example, Salesforce can automatically send an email that notifies the opportunity team when a new high-value opportunity is created.
• Time-dependent actions that Salesforce queues when the workflow rule executes. For example, Salesforce can automatically send an email reminder to the account team if a high-value opportunity is still open ten days before the specified close date. When Salesforcetriggers a workflow rule that has time-dependent actions, you can use the workflow queue to monitor and cancel pending actions.

Which Type Of Project can be developed In Force.com platform

The project is data-centered, requiring the storage and retrieval of structured data.

Structured data is the most important point. Implementing a YouTube-like application
on Force.com is not the best idea, because it primarily works with unstructured
data in the form of video streams. Force.com supports binary data, so a
video-sharing Web site is certainly possible to build. But handling large amounts of
binary data is not a focus or core competency of Force.com.A hotel reservation
system is an example of a more natural fit.

The user interface is composed primarily of wizards, grids, forms, and reports.

Force.com does not restrict you to these user interface patterns.You can implement
any type of user interface, including “rich” clients that run using Flash in the
browser, and even full desktop applications that integrate with Force.com via its
Apex Web Services API. But to capture the most benefit from the platform, stick
with structured, data-driven user interfaces that use standard Web technologies such
as HTML, CSS, and JavaScript.

The underlying business processes involve email, spreadsheets, threaded discussions,

 and hierarchies of people who participate in a distributed, asynchronous workflow.
Standard Force.com features such as Chatter,workflow, approvals, and email services
add a lot of value to these applications.They can be configured by business analysts
or controlled in-depth by developers.

 The rules around data sharing and security are fine-grained and based on organizational roles

 and user identity
User identity management and security are deep subjects and typically require high
effort to implement in a custom system.With Force.com, they are standard, highly
configurable components that you can leverage without coding.You can then spend
more time thinking through the “who can see what” scenarios rather than coding
the infrastructure to make them possible.

 The project requires integration with other systems.

Force.com is built from the ground up to interoperate with other systems at all its
layers: data, business logic, and user interface.The infrastructure is taken care of, so
you can focus on the integration design. Exchange a million rows of data between
your SQL Server database and Force.com. Call your Apex services from a legacy
J2EE application or vice versa.Add an event to a Google calendar from within
yourVisualforce user interface.These scenarios and more are fully supported by the
platform.

In Salesforce custom tables containing up to 800 fields each

Database

Force.com is built around a relational database. It allows the definition of custom tables
containing up to 800 fields each. Fields contain strongly typed data using any of the standard
relational database data types, plus rich types such as currency values, picklists, formatted
text, and phone numbers. Fields can contain validation rules to ensure data is
clean before being committed, and formulas to derive values, like cells in a spreadsheet.
Field history tracking provides an audit log of changes to chosen fields.

Custom tables can be related to each other, allowing the definition of complex data
schemas.Tables, rows, and columns can be configured with security constraints. Data and
metadata is protected against accidental deletion through a “recycling bin” metaphor.The
database schema is often modifiable instantly, without manual migration. Data is imported
from files or other sources with free tools, and APIs are provided for custom data-loading
solutions.

Data is queried via a SQL-like language called SOQL (Salesforce Object Query Language).
Full-text search is available through SOSL (Salesforce Object Search Language).
