In this post we will see some informations about Web SQL. I know you all are familiar with SQL, If not I strongly recommend you to read some basic informations here . As the name implies, Web SQL has so many similarities with SQL. So if you are good in SQL, you will love Web SQL too. Web SQL is an API which helps the developers to do some database operations in client side, like creating database, open the transaction, creating tables, inserting values to tables, deleting values, reading the data.

PostgreSQL, or Postgres, is a relational database management system that provides an implementation of the SQL querying language. It’s standards-compliant and has many advanced features like reliable transactions and concurrency without read locks.
This guide demonstrates how to quickly get Postgres up and running on an Ubuntu 20.04 server, from installing PostgreSQL to setting up a new user and database. If you’d prefer a more in-depth tutorial on installing and managing a PostgreSQL database, see How To Install and Use PostgreSQL on Ubuntu 20.04.

.NotSupportedException: The method 'Max' is not supported
This topic provides information about the way in which LINQ queries are composed and executed when you are using the WCF Data Services client and limitations of using LINQ to query a data service that implements the Open Data Protocol (OData). For more information about composing and executing queries against an OData-based data service, see Querying the Data Service (WCF Data Services). Composing LINQ Queries LINQ enables you to compose queries against a collection of objects that implements IEnumerable. Both the Add Service Reference dialog box in Visual Studio and the DataSvcUtil.exe tool are used to generate a representation of an OData service as an entity container class that inherits from DataServiceContext, as well as objects that represent the entities returned in feeds. These tools also generate properties on the entity container class for the collections that are exposed as feeds by the service. Each of these properties of the class that encapsulates the data service return a DataServiceQuery. Because the DataServiceQuery class implements the IQueryable interface defined by LINQ, the WCF Data Services you can compose a LINQ query against feeds exposed by the data service, which are translated by the client library into a query request URI that is sent to the data service on execution. Note: The set of queries expressible in the LINQ syntax is broader than those enabled in the URI syntax that is used by OData data services. A NotSupportedException is raised when the query cannot be mapped to a URI in the target data service. For more information, see the Unsupported LINQ Methods in this topic.
