The document discusses the Mormot framework, an open-source architecture that supports development with Delphi and Pascal, emphasizing dual memory management and its ability to integrate both high-level and system-level languages. It highlights extensive community support, innovative features like ORM, non-relational databases, testing methodologies, and a focus on performance. Additionally, it outlines various components and libraries included in the framework, showcasing its wide applicability and advanced capabilities for modern development.

4. Great times for us

5. Great times for us
Delphi is Hype
Delphi + Pascal > Ruby
If you say Delphi is dead,
YOU are dead!

6. Two Languages In One
Application Language
like Java C# Ruby Python
System Language
like C C++

7. Dual Memory Management
Automatic Memory Management
COW and refcount
Manual Memory Management
Uses much less CPU/RAM
Server stability

8. Dual Memory Management
Automatic Memory Management
COW and refcount
Manual Memory Management
Uses much less CPU/RAM
Server stability
ARC

9. New opportunities
New platforms
New compilers
Great communities
Third parties
Open Source

27. Design with Interfaces
What, not how
A type that comprises
abstract virtual methods
Rely on abstraction
rather than implementation

28. Design with Interfaces
Abstraction is your health
Publish classes as services
Test, mock
Write SOLID code

29. Design with Interfaces

Write SOLID code
and manage memory for you

30. Design with Interfaces

unless zeroing weak pointers

31. SOLID Principles
Single responsibility
Open/closed
Liskov substitution
Interface segregation
Dependency inversion
.. unleash interfaces!

33. Cross Cutting Features
UTF-8 JSON
TDynArray
TDocVariant
Logging
Testing
Compression
Crypto ECC
PDF
Mustache
SpiderMonkey
Uncoupled features: could be used
without the ORM/SOA/MVC framework

34. SynCommons
UTF-8 JSON
From the ground up
With objects, records,
dynamic arrays, variants, any value
Performance and integration

35. SynCommons
TDynArray
Wrapper to an existing dynamic array
TList<> on steroids
e.g. sorting, search,
binary or JSON serialization
using enhanced RTTI if available

36. SynCommons
TDynArray
In conjunction with records and variants:
value objects
data transfer objects (DTO)

37. SynCommons
TDocVariant
Stores documents
objects, arrays, variants
with low overhead
natively JSON
with late-binding support

38. SynCommons
TDocVariant
var V: variant; // stored as any variant
...
TDocVariant.New(V);
// or slightly slower V := TDocVariant.New;
V.name := 'John';
// property accessed via late-binding
V.year := 1972;
// now V contains {"name":"john","year":1972}

39. SynCommons
TDocVariant
V.name := 'Mark'; // overwrite a property value
writeln(V.name); // will write 'Mark'
V.age := 12; // add a property to the object
writeln(V.age); // will write '12'
writeln(V); // implicit conversion to JSON string
// i.e. '{"name":"Mark","age":12}'
writeln(VariantSaveJSON(V1)); // as RawUTF8

40. SynCommons

private
fName: RawUTF8;
fData: variant;
public
published
property Name: RawUTF8 read fTest write fTest
stored AS_UNIQUE;
property Data: variant read fData write fData;
end;

41. TDocVariant + mORMot.pas
property Data: variant read fData write fData;
We store a TDocVariant in Data
to mutate a SQL database
into a NoSQL engine

42. TDocVariant + mORMot.pas
property Data: variant read fData write fData;
We store a TDocVariant in Data
to mutate a SQL database
into a NoSQL engine

43. TDocVariant + mORMot.pas
var aRec: TSQLRecordData;
aID: integer;
begin
// initialization of one record
aRec := TSQLRecordData.Create;
aRec.Name := 'Joe’;
// create a TDocVariant
aRec.data := _JSONFast('{name:"Joe",age:30}');
// or we can use this overloaded constructor
aRec := TSQLRecordData.Create(
['Joe',_ObjFast(['name','Joe','age',30])]);

44. TDocVariant + mORMot.pas
// now we can play with the data, e.g. via late-binding:
writeln(aRec.Name); // will write 'Joe'
writeln(aRec.Data); // write '{"name":"Joe","age":30}
// one year older
aRec.Data.age := aRec.Data.age+1;
// add a property to the schema
aRec.Data.interests := 'football';
aID := aClient.Add(aRec);
// we stored {"name":"Joe","age":31,"interests":"footbal"}
aRec.Free;
// now we can retrieve the data e.g. via aID
end;

45. TDocVariant + mORMot.pas
property Data: variant read fData write fData;
Data will be stored as TEXT
in the underlying RDBMS

46. TDocVariant + mORMot.pas
property Data: variant read fData write fData;
Data will be stored as TEXT
in the underlying RDBMS
Of course, if the database is a MongoDB engine,
the data will be stored as a true BSON document

Fast viewer tool
Exception catch, stack trace
Used by the whole framework

48. SynCommons

begin
