Today, we committed a new patch to enable AES-NI hardware acceleration to our SynCrypto.pas unit. Intel® AES-NI is a new encryption instruction set that improves on the Advanced Encryption Standard (AES) algorithm and accelerates the encryption of data on newer processors. Of course, all this is […]

mORMot under Linux thanks to FPC
2015-01-10. Open Source › mORMot Framework
You can use the FreePascal Compiler (FPC) to compile the mORMot framework source code, targetting Windows and Linux.
Linux is a premium target for cheap and efficient server Hosting. Since mORMot has no dependency, installing a new mORMot server is as easy as copying its executable on a blank Linux host, then run it. No need to install any framework nor runtime. You could even use diverse operating systems (several Linux or Windows Server versions) in your mORMot servers farm, with minimal system requirements, and updates.
We will now see how to write your software with Linux-compiling in mind, and also give some notes about how to install a Linux Virtual Machine with Lazarus on your Windows computer, compiling both FPC and Lazarus from their SVN latest sources!

2015: the future of mORMot is BigData
2014-12-31. Open Source › mORMot Framework
How would be 2015 like for our little rodents?
Due to popular request of several users of mORMot, we identified and
designed some feature requests dedicated to BigData process.
In fact, your data is the new value, especially if you propose
SaaS (Software As A Service)
hosting to your customers, with a farm of mORMot
servers.
Recent Linux support for mORMot servers, together with the
high performance and installation ease of our executable, open the gate to
cheap cloud-based hosting.
As a consequence, a lot of information would certainly be gathered by
your mORMot servers, and a single monolithic database
is not an option any more.
For mORMot solutions hosted in cloud, a lot of data may be generated. The default SQLite3 storage engine may be less convenient, once it reaches some GB of file content. Backup becomes to be slow and inefficient, and hosting this oldest data in the main DB, probably stored on an expensive SSD, may be a lost of resource. Vertical scaling is limited by hardware and price factors.
This is were data sharding comes into scene.
Note that sharding is not replication/backup, nor clustering, nor just
spreading. We are speaking about application-level data splitting, to ease
maintenance and horizontal scalability of mORMot servers.
Data sharding could already be implemented with mORMot servers,
thanks to TSQLRestStorage:
- Using
TSQLRestStorageExternal: any table may have its own external SQL database engine, may be in its separated DB server; - Using
TSQLRestStorageMongoDB: any table may be stored on a MongoDB cluster, with its own sharding abilities; - Using
TSQLRestStorageRemote: each table may have its own remote ORM/REST server.
But when data stored in a single table tends to grow without limit, this
feature is not enough.
Let's see how the close future of mORMot looks like.

ODM magic: complex queries over NoSQL / MongoDB
2014-11-28. Open Source › mORMot Framework
You know that our mORMot is able to access directly any MongoDB database engine, allowing its ORM to become an ODM, and using NoSQL instead of SQL for the query languages.
But at mORMot level, you could share the same code between your
RDBMS and NoSQL databases.
The ORM/ODM is able to do all the conversions by itself!
Since we have just
improved this feature, it is time to enlighten its current status.

Breaking change: New SynLog and SynTests unit extracted from SynCommons.pas
2014-11-23. Open Source › Open Source libraries
In order to enhance code modularity, we extracted logging and testing features from SynCommons.pas. Discover the new SynLog.pas and SynTests.pas units! Documentation has been updated to reflect the changes. This is a breaking change... Ensure you add SynLog and/or SynTests to your uses clauses, just […]

BeDelphi 2014 Slides

We just finished our Be-Delphi 2014 sessions and drank our last beers, so
here we are.
I published some slides for this great event.

HTTP remote access for SynDB SQL execution
2014-11-18. Open Source › Open Source libraries
For mORMot, we developed a fully feature direct access layer to any RDBMS, implemented in the SynDB.pas unit.
You can use those SynDB classes to execute any SQL statement,
without any link to the framework ORM.
At reading, the resulting performance is much higher than using the standard
TDataSet component, which is in fact a true performance
bottleneck.
It has genuine features, like
column access via late-binding,
an innovative ISQLDBRows interface, and ability to directly access
the low-level binary buffers of the database clients.
We just added a nice feature to those classes: the ability to access
remotely, via plain HTTP, to any SynDB supported database!

BREAKING CHANGE - TSQLRecord.ID primary key changed to TID: Int64
2014-11-14. Open Source › mORMot Framework
Up to now, the TSQLRecord.ID property was defined in
mORMot.pas as a plain
PtrInt/NativeInt (i.e. Integer under
Win32), since it was type-cast as pointer for TSQLRecord published
properties.
We introduced a new TID type, so that the ORM primary key would
now be defined as Int64.
All the framework ORM process relies on the TSQLRecord
class.
This abstract TSQLRecord class features a lot of built-in methods,
convenient to do most of the ORM process in a generic way, at record level.
It first defines a primary key field, defined as ID:
TID, i.e. as Int64 in mORMot.pas:
type
TID = type Int64;
...
TSQLRecord = class(TObject)
...
property ID: TID read GetID write fID;
...
In fact, our ORM relies now on a Int64 primary key, matching
the SQLite3 ID/RowID primary key.
This primary key will be used as RESTful resource
identifier, for all CRUD operations.
