Create Flowcharts & Diagrams Easily With Visio® For Your Small Business. Compare Plans NowMicrosoft Visio has built-in database tools for developing logical data fashions (those who apply the relational database principle on your entity-relationship diagrams), and now not superb at conceptual modeling.I like the use of the database modeling device in Visio 2010. It offers me a snappy and manageable option to create a practical prototype of a data model with out being server connected. Not being server connected lets in me to concentrate on entities and characteristic relationships, cardinality, and so forth. without being · Here's the current state: The Visual Studio tools forAs a consequence the Unified Modeling Language (UML) and Database diagrams in Visio are broadly used as of late through an enthusiastic target audience, and our developer and IT neighborhood provide valuable comments on those diagram types. We have addressed this comments within the new Visio with an important refresh of the UML and Database templates.This Visio add-in for Database Modeling lets you create a database model from an current database.
Greetings from the Visio Team, We are happy to announce an early preview of the Database Model Diagram (sometimes called Database Reverse Engineering) as an add-in for Visio, brought to you exclusively by means of the Office Insider Program.. We are searching for a restricted collection of individuals to offer us early feedback on this add-in revel in.Data Modeling and Datastructure with MS-ACCESS and VISIO Access builders who model data, or report their data construction, regularly have a two-step procedure: 1.Model and report, the use of one set of tool tools. 2.Re-create the ensuing data structure, using every other instrument (in our case, Microsoft Access).Database templates have a contemporary, fashionable look within the new Visio. In our new approach, templates focal point on the on-canvas revel in, which makes them nice for brainstorming, free-form diagramming and collaborating on ideas. There are four database templates: Chen's, Crow's Foot, IDEF1X and UML. Each template can be used to model a database system in a special notation. We'll describe theFollow those easy steps to create a data conceptual with two entities. 1: Open Visio instrument.. 2: On the left hand side, underneath Choose Drawing Select Type, click on the category 'Database'.Click the template 'Database Model Diagram'. 3: Alternate manner of opening is to visit 'File' menu.Click New after which click 'Choose drawing sort'.

Data-connectivity features are to be had simplest to approved users of Microsoft Visio Professional 2013.
There are 4 aspects of data connectivity in Visio:
Connecting to a data source
Linking shapes to data
Displaying linked data graphically
Refreshing connected data that has modified in the data supply, updating connected shapes, and resolving any subsequent conflicts that may stand up
Typically, you way these sides in the order during which they are listed; this is, you first connect your Visio drawing to a data supply, then hyperlink shapes on your drawing to data in the data supply, show the data in related shapes graphically, and refresh the related data when vital. Each of those facets has new gadgets and contributors associated with it within the Visio object model. This subject deals with the primary of those facets, connecting your Visio drawing to a data source. For extra information about the opposite facets of data connectivity, see the following topics:
To connect your Visio drawing to a data source programmatically, you'll use the Visio API for data connectivity, which incorporates the following gadgets and their related participants:
Each Visio Document object has a DataRecordsets assortment, which is empty till you are making a connection to a data supply. To attach a Visio record to a data supply, you upload a DataRecordset object to the DataRecordsets choice of the report. A DataRecordset object in flip has a DataColumns number of DataColumn objects, every of which is mapped to a corresponding column (field) in the data source.
Data resources you'll be able to connect to include Excel spreadsheets, Access and SQL Server databases, SharePoint lists, and different OLEDB or ODBC data sources, comparable to an Oracle database. When you upload a DataRecordset object via connecting to any such data resources, Visio abstracts the connection in a DataConnection object, and the DataRecordset object is said to be attached.
You too can add a DataRecordset object by way of using an XML report that conforms to the ADO Classic (ADO model 2.x) Data Recordset XML schema as the data supply. The ensuing DataRecordset object is claimed to be connection-less. The connection between a data source and a DataRecordset object best goes a technique—from the data supply to the Visio drawing. If data in the supply changes, you can refresh the data within the drawing to mirror those adjustments. You cannot, then again, make adjustments in the data within the drawing after which push the ones changes back to the data supply.
To upload a DataRecordset object to the DataRecordsets assortment, you'll use one of the vital following three strategies, relying at the data supply you want to hook up with and whether or not you wish to have to pass the process a connection string and question command string or a saved Office Data Connection (ODC) record that accommodates the connection and query information:
The following Visual Basic for Applications (VBA) sample macro displays how you might use the Add option to connect a Visio drawing to data in an Excel worksheet, on this case, within the ORGDATA.XLS pattern workbook that is integrated with Visio:Public Sub AddDataRecordset() Dim strConnection As String Dim strCommand As String Dim strOfficePath As String Dim vsoDataRecordset As Visio.DataRecordset strOfficePath = Visio.Application.Path strConnection = "Provider=Microsoft.ACE.OLEDB.12.0;" _ & "User ID=Admin;" _ & "Data Source=" + strOfficePath + "SAMPLES33\ORGDATA.XLS;" _ & "Mode=Read;" _ & "Extended Properties=""HDR=YES;IMEX=1;MaxScanRows=0;Excel 12.0;"";" _ & "Jet OLEDB:Engine Type=34;" strCommand = "SELECT * FROM [Sheet1$]" Set vsoDataRecordset = EnergeticDocument.DataRecordsets.Add(strConnection, strCommand, 0, "Data") End Sub
If you run this code on non-English builds of Visio, the path to the document ORGDATA.XLS, proven right here as "Samples33\ORGDATA.XLS," will be different. Substitute the correct path on your model of Visio to your code.
The Add means returns a DataRecordset object and takes 4 parameters:
ConnectionIDOrString The ID of an current DataConnection object or the relationship string to specify a brand new data-source connection. If you cross the ID of an existing DataConnection object this is these days being utilized by a number of other data recordsets, the data recordsets become a transacted crew recordset. All data recordsets within the team are refreshed every time a data-refresh operation happens. You can decide a suitable connection string by means of first using the Data Selector Wizard in the Visio consumer interface (UI) to make the similar connection, recording a macro whilst operating the wizard, and then copying the connection string from the macro code.
CommandString The string that specifies the database desk or Excel worksheet and specifies the fields (columns) throughout the desk or worksheet that comprise the data you wish to have to query. The command string is also handed to the DataRecordset.Refresh manner when the data within the recordset is refreshed.
AddOptions A combination of one or more values from the VisDataRecordsetAddOptions enumeration. These values specify certain data recordset behaviors, and make it imaginable, for example, to stop the queried data within the recordset from appearing in the External Data window within the Visio UI or from being refreshed by person actions. Afteryou assign this worth, you cannot change it for the duration of the DataRecordset object.
Name An not obligatory string that provides the data recordset a display title. If you specify for data from the recordset to be displayed within the External Data window within the Visio UI, the title you move appears at the tab of that window that corresponds to the data recordset. In our example, there is no present data connection, so for the first parameter of the Add way, we cross strConnection, the relationship string we outlined. For the second one parameter, we move strCommand, the command string we defined, which directs Visio to choose all columns from the worksheet we specified. For the third parameter of the Add means, we go zero to specify default conduct of the data recordset, and for the closing parameter, we pass Org Data, the display title we defined for the data recordset.
The following sample code presentations the best way to get the DataConnection object that was once created once we added a DataRecordset object to the DataRecordsets collection. It prints the relationship string related to the DataConnection object in the Immediate window by having access to the ConnectionString belongings of the DataConnection object.Public Sub GetDataConnectionObject(vsoDataRecordset As Visio.DataRecordset) Dim vsoDataConnection As DataConnection Set vsoDataConnection = vsoDataRecordset.DataConnection Debug.Print vsoDataConnection.ConnectionString End Sub
Just as you can get the connection string associated with a DataConnection object by having access to its ConnectionString assets, you'll get the command string associated with a DataRecordset object by means of having access to its CommandString property. Both of those homes are assignable, so you'll be able to trade the data supply related to a DataRecordset object or the query related to a DataConnection object at any time, even though changes don't seem to be mirrored on your drawing till you refresh the data. For extra details about refreshing data, see About Linking Shapes to Data.
When you import data, Visio assigns integer row IDs, starting with the #1, to each and every data row in the resulting data recordset, primarily based upon the order of rows within the authentic data supply. Visio makes use of data row IDs to trace the rows when they're linked to shapes and when data is refreshed. If you wish to have to get admission to data rows programmatically, you should use these data row IDs. For details about how data-refresh operations impact row order, see About Linking Shapes to Data.
You can use the DataRecordset.GetDataRowIDs method to get an array of the IDs of all the rows in a data recordset, where each and every row represents a unmarried data report. The GetDataRowIDs means takes as its parameter a criteria string, which is a string that conforms to the guidelines specified in the ActiveX Data Object (ADO) API for surroundings the ADO.Filter belongings. By specifying appropriate standards and the use of AND and OR operators to split clauses, you'll filter the tips in the data recordset to go back simplest certain data recordset rows selectively. To follow no filter (that is, to get the entire rows), move an empty string (""). For more information about criteria strings, see the Filter Property matter in the ADO 2.x API Reference. After you retrieve the data-row IDs, you'll be able to use the DataRecordset.GetRowData way to get all of the data stored in each column within the data row. For more details about data columns, see About Linking Shapes to Data.
The following sample code displays methods to use the GetDataRowIDs and GetRowData methods to return the row ID of every row and then get the data stored in each column in each row of the data recordset passed in. It makes use of two nested For…Next loops to iterate thru all of the rows in the recordset and then, for each row, iterate through the entire columns in that row. The code shows the guidelines returned in the Immediate window. Note that you simply move an empty string to the GetDataRowIDs method to bypass filtering and get the entire rows within the recordset. After you call the procedure, note that the first set of data proven (corresponding to the primary data row) incorporates the headings for the entire data columns within the data recordset.Public Sub GetDataData(vsoDataRecordset As Visio.DataRecordset) Dim lngRowIDs() As Long Dim lngRow As Long Dim lngColumn As Long Dim varRowData As Variant 'Get the row IDs of the entire rows in the recordset lngRowIDs = vsoDataRecordset.GetDataRowIDs("") 'Iterate through the entire records in the recordset. For lngRow = LBound(lngRowIDs) To UBound(lngRowIDs) varRowData = vsoDataRecordset.GetRowData(lngRow) 'Print a separator between rows Debug.Print "------------------------------" 'Print the data stored in each and every column of a specific data row. For lngColumn = LBound(varRowData) To UBound(varRowData) Debug.Print vsoDataRecordset.DataColumns(lngColumn + 1).Name _ & Trim(Str(lngColumn)) & " = " & VarRowData(lngColumn) Next lngColumn Next lngRow End Sub Support and comments
