An Introduction to Interbase Objective Preface Terms Event:Inprise / BorCon 98 About:Presentation Paper Author:Markus Kemper Who:Interbase Presentation Group Topic:Introduction to InterBase Presenters:Markus Kemper and Brett Bandy Revision:Final Revision An Introduction To Interbase "You just bought Delphi, C++Builder or JBuilder and you've found InterBase! What's next? An InterBase support engineer will address some commonly asked product pre and post sales questions as well as some implementation issues raised by new InterBase developers." Objective My objective in writing this paper is to provide answers to many of the frequently asked InterBase questions. Reading questions and answers could be quite boring. I have attempted to consolodate the common questions into more comprehensive topics derived from them. As well, I hope to make the reader familiar with InterBase so that a new user has a good working knowledge of the product before beginning their first InterBase development project. Preface This paper is not a 'how to use' InterBase document. It is geared towards making new InterBase users aware of some of the important things to pay attention to. This paper is intended for the beginner or intermediate InterBase programmer. I make reference to Inprise's 'Borland' brand of Rapid Application Development RAD tools because I am assuming that you will be using them for upcoming development projects. Terms I think it is important to briefly define some terms. By describing them we can establish a base upon which to approach the topics within this paper. InterBase: InterBase is an ANSI SQL 92 compliant Relational Database Management System. InterBase Software Corporation is a wholly owned subsidiary of Inprise Corporation. Pre sales: The definition of pre sales is occasionally a tricky subject. The boundaries of pre sales type questions can be difficult to pinpoint. Often the related questions are non technical and tend to be repetitive. Regardless of their nature they are vital for both the success of our customers and InterBase itself. I am the Technical Sales Lead for InterBase. It has been a great experience for me in that it has forced me to wear the customers shoes and tromp around in the little known universe called InterBase. There will never be the perfect doc/example set, the all encompassing FAQ or maybe not even a totally bugless product but, there will always be the opportunity to improve all of the individual components that make up a software package. The development success of new and existing InterBase programmers is directly related to the quality of the documentation resources that InterBase Software Corporation provides. Pre Sales, to me, is any product related question not pertaining to example generation, syntax analysis, code evaluation, design aid or post installation trouble shooting. Pre sales could include subjects like; feature support confirmation, pricing, licensing, estimated systems sizing recommendations or other similar pre installation inquiries. Post Sales: The definition of post sales is much easier to define. By definition it is limited in scope to product inquiries made after purchase. Post sales issues can be lumped into product related questions like; configuration, installation, performance analysis. There is a fine line to be walked with regard to the point at which pre sales migrates itself into support or consulting. It is a natural process. It just happens. A software vendor has the duty to document its product while at the same time an application software developer wants to be self sufficient. The time at which a product related issue qualifies for reasonable monetary compensation is outside the scope of this paper. Pre Sales Inprise Database Client/Application Development Tools Inprise Corp. formerly Borland International has a long standing reputation for producing the most advanced, productive and powerful compilers in the industry. Borland's flagship RAD tool, Delphi has paved the way and set the standard for its current fleet of enterprise strength development tools. Inprise currently has three distinct software development tools that it releases under the 'Borland' brand name. The most famous tool Delphi, is built upon the Object Pascal programming language. Version 4.0 of Delphi is soon to be released. Borland has always been a leader in the C/C++ compiler arena. With the push for more robust graphical development tools Borland has incorporated its powerful C/C++ compiler technology into the award winning RAD development tool C++Builder. The current release of C++Builder is version 3.0. In keeping with the wave of new and upcoming technology and the advent of Sun Microsystems' Java programming language, Borland has delivered again with JBuilder. JBuilder is currently on release 2.0 and is setting a precedence in the market of Java based development tools. Inprise Development Tool Editions Inprise offers four different editions of each of its 'Borland' development tools. The editions are: 'Enterprise', 'Client/Server', 'Professional' and 'Standard'. Each of these aim to meet the needs of a wide range of software developers and their development tasks. Every edition, with the exception of the 'Standard' release of the Borland RAD tools comes with a free copy of the InterBase Server. A big misconception amongst new InterBase users is that there is a difference between the 'local' and 'multi-user' servers. InterBase is InterBase. Aside from the number of users available and the network capabilities, the product is exactly the same. The functionality of the InterBase Server shipped with the Borland tools is determined by the license included with each edition. Tool Edition InterBase Capability Enterprise 1 User Local InterBase Server License (IERDQ) " 5 User InterBase Server License (IERDSQ) Client Server 1 User Local InterBase Server License (IERDQ) " " 5 User InterBase Server License (IERDSQ) Professional 1 User Local InterBase Server License (IERDQ) Standard InterBase is not included InterBase Database Management and Development Tools All of the tools that ship with the InterBase product line can be found in the \bin sub directory under the InterBase root directory. The InterBase 'root' directory is determined during the installation process. InterBase installs in the following default directories. Platform Default Location Windows \ Program Files \ InterBase Corp \ InterBase Unix based / usr / interbase Novell \ sys \ interbas InterBase Tools NOTE: The documentation references below pertain to InterBase version 5.x. ISQL ISQL.exe - stands for Interactive SQL. It is a general purpose command line tool. It allows for Database Definition Language DDL creation and manipulation, data retrieval, data insertion, update and deletion as well as some limited debugging and performance tuning capabilities. (Operations Guide, page 200) Windows ISQL WISQL32.exe - is the GUI implementation of the command line tool ISQL.exe. (Operations Guide, page 18) Server Manager IBMGR32.exe - is a GUI based server and database management tool. The Server Manager encompasses the functionality of most of the command line tools. All InterBase Servers either v4.0 or greater are accessible by the Server Manager. This tool allows for database backup / restore, user administration as well as some other database related tasks like; validation, shutdown, repair and configuration. (Operations Guide, page 12 - 18) Communications Diagnostics COMDG32.exe - is a vital tool. This tool is used to test connections between InterBase Windows Clients and InterBase Servers. The Communications Diagnostic tool supports all valid InterBase protocols against all InterBase Servers version 4.0 or greater (Operations Guide, page 19, 87 - 95) License Manager IBLICENSE.exe - is, by name, rather self explanatory. The License Manager tool is used to manage (add/remove) licenses on an InterBase Server. This tool is only supported for version 5 InterBase Servers. (Operations Guide, page 19, 57) Registry Configuration REGCFG.exe - is used to configure some InterBase registry settings, InterBase Server process priority as well as control the Guardian Process run modes. (Operations Guide, page 70 - 75) GBAK GBAK.exe - is the most important tool in the bin directory. This tool is used to backup and restore databases. Backups are necessary to protect against unexpected data loss or file corruption. GBAK is also a great way to archive old databases. A backup copy is the only recommended way of preparing a database for machine transfer. By default GBAK generates a 'transportable' backup from a target database. This 'transportable' format allows a DBA to seemlessly backup databases and restore them on different InterBase Server platforms. This allows InterBase to provide a platform independent database solution. The GBAK functonality is surfaced in the Server Manager tool. (Operations Guide, page 156 - 163) GSPLIT GSPLIT.exe - is a tool new to InterBase version 5. This tool was created to solve a critical problem with regard to our support of unlimited database size. InterBase supports 'multi-file' databases. Operating systems enforce maximum file size limits (most commonly 2 GB). This presents a major problem when attempting to backup large InterBase databases. GSPLIT is to be used in conjunction with GBAK to create a 'multi-file' database backup from either a single or multi-file database. GSPLIT enables the backup of databases of practically unlimited size. (Operations Guide, page 163) GSEC GSEC.exe - is a command line tool used to manage (add/delete/modify) InterBase Server USERs'

  • Development of Cross-Platform Problem-Oriented Systems Using Specifications of Database Applications ?
    Development of cross-platform problem-oriented systems using specifications of database applications ? Alexei Hmelnov1;2[0000−0002−0125−1130] and Evgeny Fereferov1;2[0000−0002−7316−444X] 1 Matrosov Institute for System Dynamics and Control Theory of Siberian Branch of Russian Academy of Sciences, 134 Lermontov st. Irkutsk, Russia [email protected] http://idstu.irk.ru 2 Institute of Mathematics, Economics and Informatics, Irkutsk State University, Gagarin Blvd. 20, Irkutsk, Russia Abstract. We consider the approach to development of AIS (automated information system) using declarative specifications of database applica- tions (SDA). The specifications of database applications contain all the information about database structure, which is required to build a typical AIS. The information is represented in its pure form, so the specifications are rather concise. The AIS'es are implemented using general algorithms, which are directed by the specifications. We have developed algorithms for such tasks as: user interface generation, query building, report gener- ation, GIS interaction. Using the specifications of database applications and the algorithms the software system GeoARM was implemented. The technology considered was well-tried by use of the system GeoARM for development of several dozens of true-life AIS for different purposes. In this article we'll describe the approach, that we use for creation of several versions of the GeoARM engine, which use different data access libraries, from the common source code base. The resulting versions of the GeoARM engine allow us to create problem-oriented AIS'es for all the supported platforms from the single SDA. Keywords: Specifications of database applications · automated infor- mation systems · rapid application development · data access technology · source code structuring.

  • An Overview of the Usage of Default Passwords (Extended Version)
    An Overview of the Usage of Default Passwords (extended version) Brandon Knieriem, Xiaolu Zhang, Philip Levine, Frank Breitinger, and Ibrahim Baggili Cyber Forensics Research and Education Group (UNHcFREG) Tagliatela College of Engineering University of New Haven, West Haven CT, 06516, United States fbknie1, [email protected],fXZhang, FBreitinger, [email protected] Summary. The recent Mirai botnet attack demonstrated the danger of using default passwords and showed it is still a major problem in 2017. In this study we investigated several common applications and their pass- word policies. Specifically, we analyzed if these applications: (1) have default passwords or (2) allow the user to set a weak password (i.e., they do not properly enforce a password policy). In order to understand the developer decision to implement default passwords, we raised this question on many online platforms or contacted professionals. Default passwords are still a significant problem. 61% of applications inspected initially used a default or blank password. When changing the password, 58% allowed a blank password, 35% allowed a weak password of 1 char- acter. Key words: Default passwords, applications, usage, security 1 Introduction Security is often disregarded or perceived as optional to the average consumer which can be a drawback. For instance, in October 2016 a large section of the In- ternet came under attack. This attack was perpetuated by approximately 100,000 Internet of Things (IoT) appliances, refrigerators, and microwaves which were compromised and formed the Mirai botnet. Targets of this attack included Twit- ter, reddit and The New York Times all of which shut down for hours.

  • Ibsurgeon Interbase/Firebird Database Information Tool
    IBSurgeon Free Tools: User Guide © IBSurgeon, 2015, www.ib-aid.com IBSurgeon Free Tools: User Guide IBSurgeon Free Tools is a set of 3 tools for Firebird and InterBase administrators and developers, designed to facilitate several typical tasks: 1) measure response time of specific SQL query to find time when query runs slower than usual (“Response Checker”), 2) view how much data, indices, blobs, etc, are stored in your Firebird or InterBase database (“DBInfo”) 3) investigate Firebird log for errors and warnings, (“Log Viewer”) These tools are simple to use, below you can find their short overview and frequently asked questions. IBSurgeon Response Checker 1. Why do you need Response Checker? If you are trying to improve Firebird database performance, the first thing you need to define is criteria of performance optimization. And, Firebird database performance has such criteria: Average response time Maximum response time Response time should be measured with your real-world application and with your production database (or in test environment which simulates production close enough). There is no reason to measure average response time out of the scope of your real application, until you want some abstract «optimization» - or you are using test environment which is proven to be very close or even identical to your production database. Response time is what your end users will refer as «slow», «very slow» or «good enough» (end users never say that your software is «fast»). How to measure the average and maximum response times in real-world production environments running Firebird? For the basic response time measurement you can use IBSurgeon Response Checker.

  • Issn: 2278-6244 a Comparative Analysis of Sql Server And
    International Journal of Advanced Research in IT and Engineering ISSN: 2278-6244 A COMPARATIVE ANALYSIS OF SQL SERVER AND INTERBASE SERVER Ajala F. A.* Emuoyibofarhe O.J* Alamu F.O* Abstract: Data storage, information management and subsequent retrieval constitute one of the ultimate goals in Computing Technology. Choosing the right Database Management System depending on the operation of the Establishment cannot be over emphasized. To select the right server for an application, two things to be considered are how data will be accessed and modified in the application, and how the server will behave in a data access or update situation. This research work compares two Database Management Systems with different architecture; Interbase server with multigenerational architecture and SQL server with classical architecture. The analysis was based on Execution time (Insert time, Update time and Delete time), using Delphi 6 programming language as the platform and Open Database Connectivity (ODBC) as the Application Programming Interface (API). Results obtained revealed that insert time in SQL server was in the range of 95343 µs to 3783171 µs when the record size ranged from 10,000 to 1,000,000 which almost doubled the insert time for Interbase server. Update time for SQL server is about twice that for Interbase for number of records between 10,000 and 100,000, but about three to six times for higher number of records. The delete time for SQL server was about 5 times that of the Interbase server. Keywords: ODBC, Multigenerational Architecture, Classical Architecture, DBMS, SQL Server and Interbase server. *Department of Computer Science and Engineering, Ladoke Akintola University of Technology, Ogbomoso, Nigeria.

  • External Function Summary
    APPENDIX I External Function Summary Conditional Logic Functions FBUDF INULLIF (VALUE1, VALUE2) Linux, Win32 Returns NULL for a sub-expression if it resolves to a non-null value; otherwise, returns the value of the sub-expression. Applicable to flxed numeric types only and should be used only with Firebird l.O.x. With Firebird 1.5 and higher, use internal function NULLIF( ). Arguments valuel: The column or expression that is tobe evaluated. value2: A constant or expression with which valuel is to be compared. Ifthere is a match, the iNulllf expressionwill return NULL. Return value Will be NULL if valuel and value2 resolve to a match; if there is no match, then value l is returned. Notes iNulllf( ) has an effect equivalent to using the internal SQL function NULLIF(), implemented in Firebird 1.5 and higher, with flxed numeric types. The iNulllf() external function comes in three implementations: two for 32-bit and 16-bit types (inullif and dnullif), the other for 64-bit types (i64nullif). Ifyou wanttobe able to use it with any flxed numeric type, declare all implementations. The declarations can be found in the script fbudf.sql, in the /UDF directory ofyour Firebird installation. Do not declare the i64nullif implementation in any database that does not support 64-bit numeries-in an unported InterBase 5 database, for example. Example This Statement will cause the STOCK value in the PRODUCTS table to be set to NULL on all rows where it is currently stored as 0: UPDATE PRODUCTS SET STOCK = iNULLIF(STOCK, o) Related or similar See also NULLIF( ), sNulllf( ).
