You can request repair, schedule calibration, or get technical support.

A file path control, shown as follows, is a LabVIEW data type that identifies the location of a file on disk.

Enter or display a path using the standard syntax for a given platform with the path control or indicator.

Use relative paths in VIs to avoid having to rework the paths if you build an application or run the VI on a different computer.

For example, the symbolic path represents the directory in the labview directory.

At run time, LabVIEW interprets the symbolic path as an absolute path, such as C:Program Files (x86)National InstrumentsLabVIEW 2009vi.lib or D:Program FilesNational InstrumentsLabVIEW 2009vi.lib, depending on where LabVIEW is installed.

It is based on the Model-View-Controller architecture where Model View Controller It also happens to contain tools for auto-generating the models, views and controllers automatically from a database.

My name is Sam Sharp, I run my own little NI Alliance Partnership, MediaMongrels Ltd, I recently became a LabVIEW Champion (Hooray) and I am one of the founding members of GDevCon so feel free to come and talk to me if you have any feedback.

Today I am going to be talking about communicating with databases in LabVIEWbut first.

Its the first major update to the library since its release that simplifies the API, fixes some bugs, adds some features and also allows for Secure WebSockets Support in the future.

A version for LabVIEW NXG to use with the NXG Web Module will also be coming soon.

Most of my career dating back even to school has involved some form of work with databases, whether as a Web Developer writing applications in PHPMySQL or writing LabVIEW applications that interface with databases.

One thing I find when working with databases in LabVIEW is that it is TEDIOUS.

Writing VIs to talk to a database with anything more than a few tables takes ages and much of it is repeated work (insert into X, insert into Y etc.).

It is a BORING and THANKLESS TASK.

If you need any of the things on the left-hand side of the slide, you should probably put down Excel or your file-based record keeping system and consider using a database.

Relational: Structured tables with rows and columns defined in a schema.

NoSQL: Allows unstructured and semi-structured data to be storedmanipulated.

JSON in MongoDB), Key-Value pairs (Redis).

When it comes to talking to databases in LabVIEW theres the built-in database connectivity toolkit and other 3rd party toolkits such as James Powells excellent SQLite library which he will be talking about after me.

Depending on the database type youre talking to, you might need to install some additional drivers and configure your database connection.

Fortunately, the normalisation principles are there to help you.

The normalisation principles (E.g.

They are a tool to help you, but it is up to you whether to use them.

As each added relation between tables adds complexity to your database design, sometimes it is sensible to break the rules.

Here we have added the executionid to stepmeasurement to give us a faster way to look up all measurements for a particular test execution.

I can then go to a special link, click the Model Generator and enter an asterix to generate all models, youll then see that it has populated a list of all of my database tables.

I can preview the file to see the columns in the table and then generate my model files.

This has now added a user interface where I can add a new operator, view operators, update an operator and delete them.
