This series of articles will examine the purposes, uses, and optimization of cursors in SQL 2000. SQL languages are designed so groups of records, or sets, can be manipulated easily and quickly. The speed at which groups of data can be altered, updated and deleted, demonstrates why working with sets is the preferred method. However, there are places where cursors are a better choice.

A common complaint of database administrators (DBAs) is that performance bottlenecks are not among those problems that one can fix "by just throwing hardware at it."

One of the age old problems in DTS is moving packages between your development, test and production environments. Typically a series of manual edits needs to be done to all the packages to make sure that all the connection objects are pointing to the correct physical servers. This is time consuming and gives rise to the possibility of human error, particularly if the solution incorporates many DTS packages. Many companies have provided their own custom solutions for managing this problem but these are still workarounds for a problem that is inherently DTS's.

Creating an enterprise security plan is a complex endeavour. It involves evaluating multiple threats that gain access through many network paths to a hodgepodge of different applications and systems. With the focus on systems and paths, databases are frequently overlooked. Securing the database should be a fundamental tenet for any security practitioner when developing his or her security plan. The database is the source of data, the "crown jewels" in the information economy. Any security effort must start with this in mind and end with the strongest level of controls applied at the database layer.
