Error: Windows could not start the SQL Server (SQLEXPRESS) on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code -2146885628.
The Solution: Opened the "properties" dialog for the service, and on the Log On tab, changed the user from "This Account" to "Local System Account". Started the service, and bingo.
This tutorial shows how you would create a trigger in Microsoft SQL Server 2005/2008 that will date/timestamp a column named last_updated everytime any data in the row is updated.
This example assumes a primary key that includes 3 fields.
Solution: This error is caused by a defect in 11g limited to Windows Vista. The nmefwimi.exe is an Oracle 11g service used by dbconsole (OaracleDBConsoleorcl). You can stop this service to stop this error then set it's Startup Type to Manual to prevent it from returning. Doing so will not affect your database. When you need to use dbconsole, start the service manually.
Also, check with Oracle for an update that fixes this issue.
Virtualization is a concept greatly expanded in Vista. This article discusses the impact of Application Virtualization on you development. It can have a huge impact on how the programs you write will behave when installed on Vista.
Think globally, act locally. How many times have you needed to determine the geographic distance between two places? This tutorial will show you how to accomplish just that.
All data and functions exist in a SQL Server Database, and can be used in VB.NET, C#.NET, Paradox, Delphi, or any other language that can call a database function.

In this article, you will be shown a few generic methods to optimize your SQL queries. This information is not database-specific (other than in a few places) and should apply to any SQL based database.
8. Application Manifests, Revisited for Vista
Since the introducton of XP, Windows programs have benefitted from an application "Manifest." This was covered in an earlier article. This is an update to that information, pertaining to Windows Vista
by Jeffrey K. Tyzzer. In 1970, Dr. E.F. Codd's seminal paper "A Relational Model for Large Shared Databanks" was published in Communications of the ACM. This paper introduced the topic of data normalization, so-named because, at the time, President Nixon was normalizing relations with China.
Data normalization is a technique used during logical data modeling to ensure that there is only one way to know a fact, by removing all structures that provide more than one way to know the same fact as represented in a database relation (table). The goal of normalization is to control and eliminate redundancy, and mitigate the effects of modification anomalies -- which are generally insertion and deletion anomalies. (Insertion anomalies occur when the storage of information about one attribute requires additional information about a second attribute. Deletion anomalies occur when the deletion of one fact results in the loss of a second fact).
Normalization There are six generally recognized normal forms of a relation: first normal form, second normal form, third normal form, Boyce/Codd normal form, fourth normal form, and fifth normal form, also called projection/join normal form. Other normal forms (e.g., Domain/Key) exist but will not be discussed here. The normal forms are hierarchical, i.e., each normal form builds upon its predecessor. Although many people consider a relation to be normalized only when it is in third normal form, technically speaking, a relation in only first normal form can be considered...
