MS <strong>SQL</strong> <strong>Server</strong> <strong>Data</strong><strong>Server</strong> overview<br />
The <strong>OpenEdge</strong> <strong>Data</strong><strong>Server</strong> <strong>for</strong> MS <strong>SQL</strong> <strong>Server</strong> allows you to access your MS <strong>SQL</strong><br />
<strong>Server</strong> data source with the ABL and develop applications within the <strong>OpenEdge</strong>®<br />
Studio. The <strong>OpenEdge</strong> Studio is a set of tools that helps you maintain data sources and<br />
develop applications with graphical user interfaces. When you develop applications<br />
with the <strong>OpenEdge</strong> Studio, you can design a separation of your user interface,<br />
business logic, and data sources. <strong>OpenEdge</strong> Studio provides user interface<br />
independence, whether you need a character UI, a Graphical Windows UI, or a Web<br />
interface. When you incorporate a <strong>Data</strong><strong>Server</strong> with <strong>OpenEdge</strong> Studio, you are enabling<br />
the use of your ABL business logic to access a <strong>for</strong>eign data source.<br />
<strong>OpenEdge</strong> provides you to develop, deploy, manage, and integrate your application.<br />
The <strong>Data</strong><strong>Server</strong> allows you to implement the <strong>OpenEdge</strong> features and ABL expansions<br />
in applications that run with the supported data sources.<br />
Some of these tools and features are:<br />
• <strong>OpenEdge</strong>® Application <strong>Server</strong> — Use to partition your application across<br />
multiple servers.<br />
• Progress Dynamics® — Use to design and develop a repository-based<br />
application.<br />
• <strong>Data</strong> Dictionary — Use to modify database schema; create indexes; and define<br />
database triggers, validation expressions, and help messages.<br />
• <strong>Data</strong> Administration tool — Use to manage database data and per<strong>for</strong>m<br />
<strong>Data</strong><strong>Server</strong> tasks.<br />
• <strong>Data</strong>base triggers — Use to fire a block of ABL code whenever a specific data<br />
source event occurs; <strong>for</strong> example, when creating or deleting a record or assigning<br />
a value to a field.<br />
Note that using the <strong>Data</strong><strong>Server</strong> to access a MS <strong>SQL</strong> <strong>Server</strong> data source does not<br />
provide you with access to all ABL, WebSpeed, and database features. For details, see<br />
Chapter 2, “Initial Programming Considerations.”<br />
The <strong>OpenEdge</strong>® <strong>Data</strong><strong>Server</strong> <strong>for</strong> MS <strong>SQL</strong> <strong>Server</strong> is a fully featured <strong>Data</strong><strong>Server</strong> with a<br />
wide range of deployment flexibility and scalability. Its features include the following:<br />
• It is available <strong>for</strong> use by multiple users.<br />
• It can be configured on remote servers.<br />
• The ODBC driver <strong>for</strong> the data source is bundled with the product.<br />
Note: To install and use an ODBC driver successfully, your system must meet the<br />
driver system requirements <strong>for</strong> connecting to data sources. For more<br />
