NI DataFinder Server Edition: Search Engine for Technical Data A DataFinder server is a search engine that you install on a server. The DataFinder server browses specified folders on computers in a network for files that contain technical data. The DataFinder server indexes data files to provide the clients with the data properties. The DataFinder server indexes files for which DataPlugins are registered in the Server Manager. You can define several DataFinder servers in the Server Manager to provide different data for different work groups. Clients, such as LabVIEW and DIAdem, communicate with the DataFinder servers to query the indexed data and to load search results. LabVIEW DataFinder Toolkit viii ni.com

8 Introduction 1 Use the NI LabVIEW DataFinder Toolkit to work with DataFinder in LabVIEW. You can use DataFinder to search for simple texts or to execute extended queries for specific data properties, in indexed data. You can use the DataFinder Toolkit VIs to create query conditions using the logical operators AND and OR, and to access the mass data and properties of the search results. DataFinder DataFinder is a search engine you can use to find specific data in large amounts of various file formats, similar to Internet search engines. DataFinder searches for files in the search areas you specify. Search areas are file system folders that are on your local computer or on network drives. DataPlugins enable the DataFinder to index many different file formats and to search these files. All file formats indexed by DataFinder apply to the TDM data model and contain descriptive information on three different levels root, group, and channel. The TDM root object, also referred to as a file, can contain several groups, and each group can contain several channels. You can work with the TDM data model-defined set of properties at each of the three levels or insert your own custom properties. Desktop DataFinder and Remote DataFinder You can search for data using the Desktop DataFinder My DataFinder or a remote DataFinder. Use My DataFinder to run a search on your computer or on the network. You specify which search areas My DataFinder uses in a search. You cannot delete My DataFinder and you cannot create an additional Desktop DataFinder. You cannot access My DataFinder from remote computers. The DataFinder index is on your computer. In addition to My DataFinder you can use any number of remote DataFinders on your network. A remote DataFinder is a DataFinder from the NI DataFinder Server Edition and usually runs on a different computer. National Instruments Corporation 1-1 LabVIEW DataFinder Toolkit

9 Chapter 1 Introduction Configuring DataFinder Text Search and Extended Query The remote DataFinder contains the information for the connection to the other computer. NI DataFinder Server Edition enables you to configure a DataFinder and to make this DataFinder available to multiple clients on the network. In the DataFinder Server Edition configuration you can assign access rights to search areas for the individual clients. You can configure My DataFinder interactively. To do so, right-click the My DataFinder tray icon on the task bar and select Configure from the context menu. DataFinder then opens a configuration dialog box. On the Search Areas tab in the configuration dialog box you specify the search areas where My DataFinder searches for data files. For DataFinder to search for data in these search areas, the indexer must first index this data. You configure the indexing settings on the Indexer tab. You specify, for example, when files are indexed and the timeout for indexing a file. Click the DataPlugins tab of the configuration dialog box to specify which filename extensions DataFinder recognizes when searching for data. You can import and export the DataFinder configuration. To do so, click Import or Export in the DataFinder configuration dialog box. You can also configure DataFinder programmatically with the VIs Invoke Node and Property Node from the DataFinder API, which is in the DataFinder Toolkit palette. DataFinder offers you two different search functions: a basic text search and an extended query. The text search browses for the value you specify, in all the string properties of the files, groups, or channels in the search areas. You use the text search if you only have parts of the information you are searching for, or if you do not know whether the information you are searching for is stored on the file, group, or channel level. Use the Search Text VI for a text search. The extended query searches for specific values of properties stored on the file, group, or channel level. You use the extended query if you want to search for specific files, groups, or channels. You can, for example, use the serial number, the test specification, and the test status to find all the tests that have been executed for a specific unit under test. You use the Create Query VI to generate the query conditions for an extended query. To execute the search, wire the query output of Create Query VI to the Execute Query VI. LabVIEW DataFinder Toolkit 1-2 ni.com

10 Chapter 1 Introduction Evaluating Search Results In the extended query, you can use the Merge Queries VI to combine query conditions with the logical operators AND and OR. If you execute a search with the VIs Search Text or Create Query and Execute Query, you can then evaluate the returned results. The Results To Waveforms VI extracts the signals from the search results returned by the VIs Search Text and Execute Query, which allows you to, for example, graphically display the signals. The Get Property Values VI extracts values of one or more properties of the returned results. The DataFinder Toolkit Palette To open the DataFinder Toolkit palette, right-click the block diagram and select Connectivity»DataFinder Toolkit. The DataFinder Toolkit palette contains the following VIs: Search Text: Searches for text. Use the text search if you only have parts of the information you are searching for, or if you do not know whether the information you are searching for is stored on the file, group, or channel level. Create Query: Generates a query condition. You can search for text, paths, numeric values, and time/date values. Use the Merge Queries VI to combine multiple query conditions with each other. Use the Execute Query VI to execute the query condition. Merge Queries: Combines multiple query conditions into one query condition with the logical operators AND or OR. Use the Create Query VI to define the query conditions. Execute Query: Executes a query. Use the VIs Create Query and Merge Queries to define the query conditions. ResultsToWaveform: Extracts the signals from the search results returned by the VIs Search Text and Execute Query, to, for example, graphically display these signals. Get Property Values: Extracts the values of one or more properties of the search result references returned by the VIs Search Text and Execute Query. National Instruments Corporation 1-3 LabVIEW DataFinder Toolkit

11 Chapter 1 Introduction Get Indexed Properties: Determines the list of all indexed properties you can use to execute a query. Open DataFinder: Connects a DataFinder. Close Reference: Closes a DataFinder connection, a reference to a query condition, or references to the search results. The following figure shows the VIs in relation to each other: Figure 1-1.

17 Connecting Other LabVIEW Components 3 You can use the DataFinder Toolkit VIs in combination with other LabVIEW VIs. In the following you will learn how to use the TDM Streaming VIs and the Read From Measurement File Express VI to process the results of a simple text search. Additionally you will learn how to use the Storage VIs to process the results of an extended query. Processing a Text Search with the TDM Streaming VIs Use the TDM Streaming VIs to read and write signals and properties of TDMS files. The following example executes an extended query for channel groups and loads the found channel groups. The returned TDMS full paths are passed to the TDMS Open VI to open the file. The returned channel group names are passed to the TDMS Read VI to extract the signals of the channels in the resulting channel groups. Then the signals are displayed as waveforms. Figure 3-1. Processing a Text Search with the TDM Streaming VIs National Instruments Corporation 3-1 LabVIEW DataFinder Toolkit

18 Chapter 3 Connecting Other LabVIEW Components Processing Results of a Text Search with the Read From Measurement File Express VI The Read from Measurement File Express VI is for reading data from text files with measurement values (*.lvm) or from binary files with measurement values (*.tdm and *.tdms). The following example first executes a simple text search. It uses the DataPlugin names to differentiate between LVM, TDM, or TDMS files and the full path to read the data with the Read From Measurement File Express VI. The example then displays the search results as waveforms. Figure 3-2. Processing Results of a Text Search with the Read From Measurement File Express VI LabVIEW DataFinder Toolkit 3-2 ni.com

19 Chapter 3 Connecting Other LabVIEW Components Processing Results of an Extended Query with the Storage VIs Use the Storage VIs to read and write signals and properties of TDM or TDMS files. The following example first uses the Create Query VI to generate an extended query. The Execute Query VI searches for channels of TDM or TDMS files and transfers the channel names, paths, DataPlugin names and channel group names to the Read Data VIs, which read out the signals. The example then displays the search results as waveforms. Figure 3-3. Processing Results of an Extended Query with the Storage VIs National Instruments Corporation 3-3 LabVIEW DataFinder Toolkit
