Establishing a usable database environment requires a great deal of skill, knowledge, and consideration. This chapter will outline the principles involved in establishing a usable database environment. This chapter is from the book One of the primary tasks associated with the job of DBA is the process of choosing and installing a DBMS. Premiere Pro Cs6 Presets Free Download here. Unfortunately, many business executives and IT professionals without database management background assume that once the DBMS is installed, the bulk of the work is done. The truth is, choosing and installing the DBMS is hardly the most difficult part of a DBAs job. Establishing a usable database environment requires a great deal of skill, knowledge, and consideration. This chapter will outline the principles involved in establishing a usable database environment. The process of choosing a suitable DBMS for enterprise database management is not as difficult as it used to be. The number of major DBMS vendors has dwindled due to industry consolidation and domination of the sector by a few very large players. Yet, large and medium size organizations typically run multiple DBMS products, from as few as two to as many as ten. For example, it is not uncommon for a large company to use IMS or IDMS and DB2 on the mainframe, Oracle and My. SQL on several different UNIX servers, Microsoft SQL Server on Windows servers, as well as pockets of other DBMS products such as Sybase, Ingres, Adabas, and Postgre. SQL on various platforms, not to mention single user PC DBMS products such as Microsoft Access, Paradox, and File.

Who chose to install all these DBMSs and why Unfortunately, often the answer is that not much thought and planning went into the decision making process. Sometimes the decision to purchase and install a new DBMS is driven by a business need or a new application. This is reasonable if your organization has no DBMS and must purchase one for the first time. VMwareplayer_screenshot.png' alt='How To Install Teradata On Vmware Player' title='How To Install Teradata On Vmware Player' />This is rarely the case, though. Regardless of whether a DBMS exists on site, a new DBMS is often viewed as a requirement for a new application. Sometimes a new DBMS product is purchased and installed without first examining if the application could be successfully implemented using an existing DBMS. Or, more likely, the DBAs know the application can be implemented using an existing DBMS but lack the organizational power or support to reject a new DBMS proposal. There are other reasons for the existence of multiple DBMS platforms in a single organization. Perhaps the company purchased a commercial off the shelf application package that does not run on any of the current DBMS platforms. Sometimes the decision to buy a new DBMS is driven by the desire to support the latest and greatest technology. For example, many mainframe shops moving from a hierarchic IMS or CODASYL IDMS database model to the relational model deployed DB2, resulting in an additional DBMS to learn and support. Then, when clientserver computing became popular, additional DBMSs were implemented on UNIX, Linux, and Windows servers. Once a DBMS is installed, removal can be difficult because of incompatibilities among the different DBMSs and the necessity of converting application code. Furthermore, when a new DBMS is installed, old applications and databases are usually not migrated to it. Super Mario World Pc Completo'>Super Mario World Pc Completo. The old DBMS remains and must continue to be supported. This complicates the DBAs job. So what should be done Well, the DBA group should be empowered to make the DBMS decisions for the organization. No business unit should be allowed to purchase a DBMS without the permission of the DBA group.

Business politics often work against the DBA group because it frequently possesses less organizational power than other business executives. Choosing a DBMSThe DBA group should set a policy regarding the DBMS products to be supported within the organization. Whenever possible, the policy should minimize the number of different DBMS products. For a shop with multiple operating systems and multiple types of hardware, choose a default DBMS for the platform. Discourage deviation from the default unless a compelling business case existsa business case that passes the technical inspection of the DBA group.

Most of the major DBMS products have similar features, and if the feature or functionality does not exist today, it probably will within 1. So, exercise caution before deciding to choose a DBMS based solely on its ability to support a specific feature. When choosing a DBMS, it is wise to select a product from a tier 1 vendor as listed in Table 2. Tier 1 represents the largest vendors having the most heavily implemented and supported products on the market.

Both are popular and support just about any type of database. Another major player is Microsoft SQL Server, but only for Windows platforms. DB2 and Oracle run on multiple platforms ranging from mainframe to UNIX, as well as Windows and even handheld devices. Choosing a DBMS other than these three should be done only under specific circumstances. Table 2. 1. Tier 1 DBMS Vendors. DBMS Vendor. DBMS Product. IBM Corporation. DB2. New Orchard Road.

All of these offerings are quality DBMS products, but their installed base is smaller, their products are engineered and marketed for niche purposes, or the companies are smaller with fewer resources than the Big Three IBM, Oracle, and Microsoft, so there is some risk in choosing a DBMS from tier 2 instead of tier 1. However, there may be solid reasons for deploying a tier 2 solution, such as the high performance offered by Informix or the data warehousing and analytics capabilities of Teradata. Table 2. 2.
