Target Environment: Delphi 4, 5, 6, 7 and C++ Builder 4, 5, 6.Company information-------------------Company Name: AidAim SoftwareContact E-mail Address: support@aidaim.comContact WWW URL: http://www.aidaim.comDescription-----------SQLMemTable is a compact in-memory table with SQL support for Delphi and C++ Builder. SQLMemTable does not require BDE and provides all the TTable‘s functionssuch as Master/Detail relationship, Filtering, Searching, Sorting, Key, Range, BLOB fields, and has some advanced features such as BLOB data compression, multi-indexes and table restructuring, shareable in memory capabilities. It is fully compatible with all standard DB controls, supports calculated and lookup fields as well as internationalization/localization and Unicode, provides data importing from and exporting to any dataset, includes SQLConsole utility with source code, comprehensive help and demos.SQLMemTable provides the following services: - SQL support - Master / detail relationship - Creating, renaming, emptying, deleting and restructuring tables - Creating, editing, deleting, navigating and searching for records - Creating and deleting multiple indexes - Calculated and lookup fields - Filtering support - Using BLOB fields with data compression ability - Importing from and exporting to any dataset in fast and easy way - Internationalization/Localization and Unicode supportSQLMemTable does not require BDE or any external drivers and has small footprint. Its search performance is excellent and data access speed is extremely fast.Specification-------------Data types: ftAutoInc, ftInteger, ftSmallInt, ftFloat, ftDateTime, ftDate, ftTime, ftBLOB, ftMemo, ftGraphic, ftString (any fixed length string), ftCurrency, ftWord, ftBoolean, ftLargeInt, ftFmtMemo, ftBytes, ftWideString.Advanced data types: aftExtended, aftWideMemoMaximum records quantity: up to 2^31 (over 2 billions). Maximum fields per table: 2^31 (over 2 billions). Maximum indexes per table: 2^31 (over 2 billions). Maximum index fields per index: 2^31 (over 2 billions). Maximum field name‘s length: 255 characters.Maximum index name‘s length: 255 characters.BLOB fields block size: > 1 byte, default 100 Kb. BLOB compression: ZLib, BZip, PPM Search operators: <,>,=,<>,<=,>=, like, not like, is null, is not null, and, or, not, (). Features and Benefits---------------------Compactness. - Short compiled code with approximate size 300 Kb, no external drivers (such as BDE) required. - Small memory consumption by SQLMemTable database engine. - Fast BLOB data compression. Your large data fields will need less memory. SQLMemTable can compress data on the fly. The compression routines used in the SQLMemTable are much faster than most of popular archivers like PKZip, WinRar, Arj. High performance. - Fast search by B-tree indexes. At the moment SQLMemTable is one of the fastest existing in-memory tables for Delphi and C++ Builder. - High-speed memory operations performance is achieved by means of using specially optimized memory manager and tuned algorithms. - Quick operations with strings. SQLMemTable compares strings up to 3 times faster than standard Delphi string routines. High performance is achieved by using a special library written in Assembler and an advanced sorting algorithm. - Advanced SQL optimizer often makes query execution several times faster by choosing the best execution plans. Functionality. - A subset of SQL‘92 including DDL operators is supported by TSQLMemQuery component. With SQLMemTable you can create SQL scripts for creating tables, inserting, editing and deleting records, retrieving data by SELECT command. - Advanced search engine. SQLMemTable supports ‘LIKE‘ operator with wildcards ‘%‘ and ‘_‘, as well as ‘IS NULL‘ and ‘IS NOT NULL‘ in filters and queries. - Full multiple index support, i.e. numerous fields in a table may comprise an index. SQLMemTable provides descending and ascending indexes, case-sensitive and insensitive indexes for string fields. - Shareable in-memory tables. SQLMemTable supports simultaneous access to a table by multiple TSQLMemTable components within a single application. - Default values support. - Record-level constraints, i.e. constraints that must be met when editing the data. Compatibility. - SQLMemTable supports most of TTable field data types, including BLOB fields, moreover it allows to create string and wide string fields of any fixed length. - SQLMemTable is fully compatible with standard DB-aware visual controls such as QuickReport, DBGrid, DBNavigator, DBImage, DBMemo, DBRichEdit, as well as with third party vendor‘s products supporting TDataset descendant components - FastReport, DBFlyTreeView and others. - Calculated and lookup fields can be used in the same way as TTable. - Most of TTable functions are supported including Key and Range methods. Convenience. - Table restructuring is being performed in the easiest way keeping all the existing data. - Data importing from and exporting to any dataset is supported. SQLMemTable provides you with the simplest way to import and export tables using ImportTable and ExportTable methods. - Internationalization / localization support. All text search and sorting functions use current system locale, so localizing your program with SQLMemTable is a very simple task. - Unicode support. All the text operations work with multi-byte encoding using ftWideString. - Comprehensive help. SQLMemTable comes with full documentation presented in SQLMemTable Developer‘s Guide and SQLMemTable Reference. Installation------------1) Make sure that all copies of Delphi (or C++ Builder) are currently closed and not running on the target system.

FastReport Software -------------------Advanced report generators for Delphi and Kylix.Web Site: http://www.fast-report.comFastReport VCL--------------FastReport VCL is reporting tool component for Borland Delphi 2-6 and Borland C++Builder 3-5. It consists of report engine, designer and preview. Some FastReport possibilities are really unique. The generator allows you to create tables, queries and databases in run-time. Built-in dialog designer allows you creation of dialog forms (they can be used for asking some parameters before printing a report). You also able to use built-in Pascal-like interpreter to do rather complex data processing. In spite of power of FastReport, its code is quite small. Probably FastReport is leader in correlation of functionality/size. The FastReport kernel (without designer) adds to your program the small footprint (less than QR3), but its functionality is like in ReportBuilder‘s one.FastReport CLX edition----------------------FastReport CLX edition is powerfull of FastReport for Borland Delphi 6 and Borland Kylix 1-2 for Linux. It use new CLX-library. Do you want to create reports for Linux as well as for Windows? Use FastReport CLX edition!FastReport VCL 2.3 lite-----------------------FreeWare version of FastReport.
