When a tabular model is created using Visual Studio, the JSON representing the TOM metadata is stored in a file called Model.bim.All of this information is collectively called the model metadata, and it is stored in a JSON based format known as the Tabular Object Model (TOM). Typically, the data model also defines relationships between tables, data sources containing connection details and table partitions containing data source expressions (SQL or M queries) for loading data, etc. Each table has one or more columns, and a table may also contain measures and hierarchies. Tabular Object Model (TOM) metadataĪ data model is made up by a number of tables. Similarly, when we use term Analysis Services, we mean "any instance of Analysis Services", which could be SQL Server Analysis Services, Power BI Desktop or the Power BI Service XMLA Endpoint. Thank you very much for reading and stay safe!.We use the term tabular model to represent both Analysis Services Tabular models as well as Power BI datasets, since Analysis Services Tabular is the data model engine used by Power BI. At the same time, I will update this post if I come across anything new. Therefore, I suggest you try it out by yourself and see how much it helps to your day-today development tasks. ![]() If you put a description to each object inside the model, this tool can extract all meta data and description and will generate a documentation about the model.Ĭovering all the features of these awesome tools from a single blog post is not a feasible task. Apart from that it can be used to document your Power BI model. It extracts the meta data of a Power BI model and visualize in a nicely organized way so that you can understand impact and usage easily. Power BI helper allows you to understand a Power BI model.
