This is our last blog post about what’s new in List & Label 29, so let’s take a look at features we haven’t presented yet. Highlights include native .NET 8 assemblies, new data providers, and enhanced report design options.
The features of different data providers vary widely. Depending on the data source, sorting, native aggregate functions or filters at database level may be available directly. Or not. For example, none of this is available in file-based formats such as JSON or XML, or even in “web” formats such as REST. These are typically read “front to back” and therefore cannot offer sorting or native aggregation. With List & Label 29, we have something new to offer.
Azure Cosmos DB is a fully managed Microsoft NoSQL database for modern app development, which is growing in popularity. Various APIs are available for connecting to Cosmos DB, as for example SQL API, Cassandra API or MongoDB API. Since we’re already able to connect to MongoDB or Cassandra through their own data providers, we’ll use the SQL API for the provider.
List & Label 28 provides some new features and improvements for .NET developers. Most important, we’re now supporting the just released .NET 7. Performancewise, the optimized use of byte arrays for images makes a noticeable difference. And there’s also news regarding the support of new data sources. Here’s a list of the new features.
GraphQL was publicly released in 2015 and became quite popular since then. It's used by a number of big web applications like Instagram, Facebook and others.
Redis is an in-memory key-value database, so a typical NoSQL database. Since its initial release in 2009, it has become quite popular and now is, according to db-engines.com by far the most popular key-value database out there. With the new RedisDataProvider you can now use your Redis database within List & Label or Report Server.
No matter which data, using the DataProvider interface you can write your own custom binding. And of course we ship a whole family of providers with List & Label. In LL23, there's a new member of this family that allows your applications to connect to Salesforce data easily.
The .NET DataProvider concept allows to bind to almost any data source. Basically, it mimics a relational database management system containing tables, relations, sort orders etc. However, often you'll find yourself needing to combine data from different sources, e.g. a server log file that contains customer logins and a SQL customer database that contains all pertinent information about the customers.
The IDataProvider interface for .NET has enabled many features that are not available for all of the other platforms so far. Most importantly, it brings multiple report containers and nested tables. For C++, we've included a sample in LL21. This is sadly missing in Delphi. In addition, the current Delphi data-binding engine still works against the BDE, a technology that has been deprecated quite a while ago by Embarcadero.
