Marie-Sophie Landrieu-Yvert has joined the 4D Product team as a Product Owner in 2017. As a Product Owner, she is in charge of writing the user stories then translating it to functional specifications. Her role is also to make sure that the feature implementation delivered is meeting the customer need.

Marie-Sophie graduated from the ESIGELEC Engineering School and began her career as an engineer at IBM in 1995. She participated on various projects (maintenance or build projects) and worked as a Cobol developer. Then she worked as an UML designer and Java developer. Lately her main roles were analyzing and writing functional requirements, coordinate business and development teams.

Add values to your generic ORDA queries

Automatically translated from English

By now you’ve surely noticed that ORDA queries are not only light and readable, they also make it easy to navigate through the entire data model using object-oriented concepts! In this blog post, we showed you how to write powerful and easy-to-maintain queries. One of the methods recommended was providing the query and values separately via placeholders. 4D v17 R5 takes placeholders a step further by allowing you to write generic ORDA queries: say hello to named placeholders for values!

Improved performance: up to 8xs faster (no, that’s not a typo)!

Automatically translated from English

Scalability is one of our primary concerns and 4D v17 R5 brings good news in this area, particularly for those with a heavy process load on their 4D Server. You’ll notice significant improved performance speeds when remote clients (one, two, or even hundreds) are connected to your server.

4D’s internal architecture has been enhanced and now processor usage is fully optimizedopens in a new tab) in preemptive mode and simultaneous read/write accesses on the same table. As a result, you could see performance 4 to 8xs faster!

Read 4D object fields with SQL Engine

Automatically translated from English

A 4D object field is a persistent database field type, stored as binary content. Previously, reading this type of field by an ODBC driver wasn’t possible. Until today.

Before, an error was returned when trying to read an object field. This prevented the completion of simple Select * from myTable requests, which could be frustrating for users who only wanted to browse the content of a table.

Good news! The SQL engine has been updated to allow 4D object fields to be read.

Introduction to data encryption in 4D

Automatically translated from English

DATA is everywhere. As our lives increasingly move online, the importance of data security also increases. Customer data must be vigilantly guarded against potential threats and breaches. In many cases, using a disk encryption tool (such as Microsoft’s Bitlocker or Apple’s FileVault) provides a sufficient level of protection, but what if your customer or your CSO (Chief Security Officer) requires encryption at the database level – on a per table basis?

During 4D Summit 2018, you asked for a solution to encrypt your data and we’ve delivered. We’re excited to present new data encryption tools for your 4D databases.

Get info about the running application

Automatically translated from English

4D v17 R3 takes your database analysis a step further by enabling you to create a customized server administration dialog. Following the ability to retrieve information about users & processes, getting all runtime information about 4D Web server, getting details about the active license, and getting all of the hardware and system details, you now also have the ability to retrieve the activity and network configuration of the running database.

Do you need to know on which IP address and port the database is listening, if communications between the client and the server are encrypted, or if the legacy network layer is used? Just call the new command, Get application info. And that’s not all! This command also returns information about the database such as: the amount of CPU used, the time since its been started, and the list goes on.

Get machine hardware information

Automatically translated from English

4D v17 goes a step further to let you create a customized server administration dialog. Following the ability to retrieve information about users & processes, getting all runtime information about 4D Web server, as well as details about the active license, you now have the ability to also retrieve all of the hardware and system details for the machine running your 4D server.

Do you need to know what OS is being used, what processor(s), how much RAM is available, etc.? Just call the new Get system info command, locally or remotely! And that’s not all, this command can be extremely useful for quickly diagnosing and solving any problems that may arise.
