Sample 04 - HTTP Client-Server
purpose of this sample is to show HTTP Client/Server SQLite3 database usage:
- a TSQLSampleRecord class is defined in shared unit SampleData.pas
- this sample uses two projects, Project04Client.dpr and Project04Server.dpr
- a SQLite3 server is initialized in Project04Server
- the CreateMissingTables method will create all necessary tables in the
SQLite3 database
- one or more client instances can be run in Project04Client
- the purpose of the Client form in Unit1.pas is to add a record to the
database; the Time field is filled with the current date and time
- the 'Find a previous message' button show how to perform a basic query
- since the framework use UTF-8 encoding, we use some basic functions for
fast conversion to/from the User Interface; in real applications,
you should better use our SQLite3i18n unit and the corresponding
TLanguageFile.StringToUTF8() and TLanguageFile.UTF8ToString() methods
- note that you didn't need to write any SQL statement, only define a
class and call some methods; even the query was made very easy (just an
obvious WHERE clause to write)
- thanks to the true object oriented modeling of the framework, the same
exact Unit1 is used for both static in-memory database engine, or
with SQLite3 database storage, in local mode or in Client/Server mode:
only the TForm1.Database object creation instance was modified
- look at the tiny size of the EXE (even with SQLite3 engine embedded), less
than 400KB for the server, and 80KB for the client, with LVCL :)
Version 1.0 - February 07, 2010
