The Multi-Platform DBA ChallengeIncreasingly, database administrators (DBAs) are expected to do things faster, cheaper, and

bettereven while working with multiple database platforms. In December 2010, Embarcadero

Technologies, a provider of cross-platform database productivity tools, published survey results

showing that 80 percent of DBAs support at least two different database platforms, and 47

percent support three or more (Figure 1).1 In addition, the survey results indicated that 30percent of people surveyed expected their company to add a new database platform within the

next 12 months.

Figure 1: Organizations supporting multiple database platforms

At the same time, Microsoft SQL Server is the most widely deployed database server on the

planet according to a 2011 IDC study on database platform unit share2. Therefore, it is likely to

be one of the multiple database platforms that DBAs will encounter in their organizations. In

addition, many customers now deploy SQL Server for mission-critical transaction processing orbusiness intelligence workloads that may have run exclusively on Oracle in the past.

How can Oracle DBAs turn this trend into an advantage? The answer may be simple: By

enhancing existing skills and experience, Oracle DBAs can become bilingual Oracle and SQL

Server DBAs, increasing their value to the organization with a broader skill set on multiple

database platforms.

Organizations today seem to favor bilingual DBAs as well. Why? Mergers and acquisitions often

bring companies with disparate systems and database platforms under one roof. A business

might decide to implement a third-party application running on SQL Server. New custom

applications may be developed on the Microsoft platform, requiring that DBAs support SQLServer. Furthermore, organizations might start using SQL Server to meet their database needs

for new deployments. All of these factors contribute to the creation of a heterogeneous

database environment, and that inevitably brings a rise in the importance of the DBA role.

With data being at the center of many emerging technologies, DBAs data management skills

become crucial for the success of the organization. According to IDC, the amount of digital data

produced worldwide is expected to grow by more than 40 times during this decade.3 This is due

in no small part to the explosion of mobile computing. Today, the United States averages 4.3

connected devices per adult, and these devices are playing an increasingly important role in

business computing. Chief information officers (CIOs) are looking for ways that these emergingtechnologies can help to create new opportunities to address business priorities. As a DBA, you

likely will be asked to tie these technologies together and manage them in a way that maximizes

opportunities for the business. According to Dan Sutherland ofThe Data Administration

Newsletter, this is a sign of the evolution of the DBA role into that of the information architect,

who collaborates more closely than ever with business stakeholders.4

In this environment, bilingual DBAs are well positioned to become indispensable IT pros by

keeping an open mind about technology options and broadening their technology skill sets while

working closely with the business. According to yet another industry analyst, such IT

professionals have the following attributes, among others:

They have a broad technical horizon.

They have mentors or even become mentors themselves, sharing valuable knowledge

with others.

They routinely take on the most complex business challenges because they know that is

where the best opportunities lie.

In short, becoming a bilingual Oracle and SQL Server DBA can be a strong path to becoming an

indispensable IT pro.

Multi-Tool Enterprise EnvironmentAs an Oracle DBA, you may not realize that SQL Server already could be present in your

organization. For example, if your company uses Microsoft SharePoint portal for collaboration

and content management services, SharePoint uses SQL Server for a back-end database.

PowerPivot in Microsoft Excel integrates with SharePoint 2010 and SQL Server. Further, SQL

Server often is paired with the integration, reporting, and analysis services that support business

intelligence solutions. Finally, many third-party applications and in-house custom applications

may be using SQL Server as their database.

Commonality with Oracle Tools

While SQL Server may be an unfamiliar to you, there is good news: there is plenty of

commonality between Oracle technologies and tools that you already know and Microsoft SQL

Server technologies and tools, as shown in the following examples.

High Availability

For online transaction processing applications that require high availability, the new Microsoft

SQL Server 2012 Availability Groups5 may seem very similar to Oracle Active Data Guard. For

example, with Active Data Guard, you can use your standby database for read-only access,

while the AlwaysOn Availability Groups has the same capability with its active secondary

feature.

Data Compression

For data warehousing solutions, SQL Server 2012 offers table-level data compression6 and

columnstore indexes7 to reduce disk storage and improve query execution times. These

capabilities are similar to those found in Oracle Advanced Compression. With Oracle Advanced

Compression, you can compress backups using Oracle Recovery Manager. Likewise, with SQL

Server, you can specify the use of compressed backups.

Manageability

For manageability, the SQL Server Utility8 for multi-server management, as well as policy-

based management9 capabilities within SQL Server Management Studio, are similar to Oracle

Enterprise Manager Grid Control.

Database Programming

For database developers using PL/SQL, SQL Server uses a similar language called Transact-

SQL (T-SQL). While there are many differences between the two languages, there also is

significant commonality in terms of functionality. For example, PL/SQL uses CONNECT BY

statements for hierarchical queries, while SQL Server implements these queries by using

common table expressions. With SQL Server 2012, the new Sequence object10 is very similar to

a PL/SQL Sequence. For more information about these and other similarities, see the Guide to

Migrating from Oracle to SQL Server 2008 white paper11.
