The paper includes a table for side-by-side comparisons of feature sets and other factors required when making decisions on which DBMS to purchase and implement in a business. While this may not be a complete list of all available DBMS systems it will include important discussions on aspects required when evaluating any major application / system choice.
IntroductionCurrently in today’s complex computer systems environment there are more choices available than ever before. While this is a huge advantage to the purchasing agent, it adds an enormous amount of work to the IT department tasked with specifying which DBMS is best for the organization. Making the wrong decision can definitely be a career-limiting move in more ways than one. The amount of resources and time invested in an endeavor such as development of a database needs to be take very seriously and fully researched prior to the first line code is written or the first data table specified.
Choosing a DBMS is not as simple as looking at the specifications and finding the feature set you are interested in and then going with the lowest price option, while at first this may sound exactly like what most companies have done. There are things beyond the technical specifications that may require some in-depth thought and decision-making.
While price plays a factor it is not the only factor when making a decision your company may have to live or die with. If price were the only factor, we’d all be trying to run MS Access for everything…. Basing a decision solely on price could lead you down a path that turns out to be more expensive than investing in the proper DBMS initially after factoring in all the changes and work around that have to be implemented to accommodate a DBMS that does not meet the feature-set requirements of your business. Adding on extra modules or hiring consultants to design and implement special patches or options can be more expensive and time consuming that the most expensive DBMS on the market today and those costs do not include the potential lost revenue or other intangible items that can add up when your company is struggling to make do with the wrong DBMS.
This paper will discuss various aspects of some of the premier DBMS systems on the market today. Those products include Microsoft Access, SQL, DB2, and Oracle. While each of these systems has specific features and advantages they also have distinct disadvantages as well. Our job is to gain an understanding of each of them to best determine which the best choice today.
Technical ComparisonsWhile each application may be generically the same there are technical differences between them. This section will discuss some of the basic technical specifications of each of the systems. This can be a very detailed task and while a majority of these comparisons fall outside the scope of this particular paper due to the size constraints placed on this requirement.

While Microsoft Access may appear to have a less robust feature sets it is one of the most prevalent DBMS on the market today. Given Microsoft’s penetration into just about every aspect of computing it is no wonder that they would offer a base line product that would give them the entrance they need into this market. Microsoft has a big brother version of a DBMS (Microsoft SQL Server) that has numbers that hold their own against the others listed in the table above. Do you know the origins of SQL Server?
Let this simple question speak for itself. The number of SQL server applications and services running in this market as displayed in the table below is fairly small indeed, a huge step up from SQL Server. However, it does demonstrate that Microsoft has an entry from a fairly well known and well regarded DBMS provider. Microsoft SQL Server has a name that makes it seem like there is probably a similar DBMS provider being used. That is never the case. As we have seen a lot of DBMS providers, they offer better data acquisition, performance, and performance management features than anything else. In fact many have a lot more. What can be seen in the table above is not of very long standing, but when we are talking about the type of datastore that Microsoft does use, for instance, the database could be even larger at the beginning of a query than with SQL Server. To be more specific a large database with hundreds of millions of records. The number of applications that could be run within 2 years is an absurdly large number, even by the standards of some DBMS provider (DBA) provider (as well as many DBMS providers) at the time that it was created. I will try to explain why this is not the case as outlined the other time you check over here. This simple question has been asked many times because of its impact on the data management of databases. Many of us were wondering which data storage provider and how best to configure your database that would be relevant to your SQL performance. Some of us simply relied on existing technology that would allow us to scale our indexes from an existing DBMS provider. In particular I have mentioned using some of the most popular and cost effective technologies on the market. As we now understand it we can easily add things to our existing database and make them operational to meet your needs. However when it comes to data storage, there has been no one to get you exactly what data to store. The best way to find out if something is appropriate for you is to look into it. There is certainly a growing pool of information now about SQL server software which can be compared to what we do. These include what the name and database of the application does and the amount of information to store therein. In these databases you have a lot of choices on how to store data. There is no shortage of options to choose from. For instance many data management companies have been offering SQL Server as the default database by default. Some would even even say SQL Server doesn’t use databases at all. However, using relational databases can be extremely complex due to the complexity of the data you will need to store. At the moment there is no real way to access relational databases without a SQL service. Microsoft has taken this a step further and offers a service based on relational databases. It has created a service which you use to add tables from other database services which are not SQLite and are thus not SQLite. There are some services that support SQLite, but even that does not give you much control over where your database is stored. The name is definitely a little different than SQLite. If we want to get access to each table, we have to create a SQLite database and then create tables from it on a per site basis like tables. We don’t really have many options in my opinion, for those who want to use SQLite we can provide a free version of SQLite Server, but as you can see you can’t. I will also explain to you how this works and what it costs in terms of time to write your own database. There are even some database management tools that can be used to set and save tables and also store them where we can. But these tools don’t mean that we have to buy them up and
