Does Ur Cervix Get Soft Before Ur Period

Portable open source world's most advanced

Without doubt one of the management systems database with more development activity in the market is PostgreSQL, which besides being Software Free BSD is licensed permitting their use and handling of your code in non-free.
While their use is not as widespread as the MySql (which is not entirely free) is a more robust and secure than the commercial RDBMS, besides complying fully with the work assigned.

Its main features can quote:

    High Concurrecia
Through a system called MVCC (multiversion concurrent access, for its acronym in English) while PostgreSQL allows a process writes to a table, others access to the same table without locks. Each user gets a consistent view of the last thing that made him commit. This strategy is superior to the use of locks per table rows or common in other bases, eliminating the need to use explicit locks.

  • Wide variety of native types
PostgreSQL natively provides support for:

* arbitrary precision numbers.
* Text of unlimited length.
* Shapes (with a variety of related functions)
* IP addresses (IPv4 and IPv6.) Blocks
* CIDR-style addresses.
* MAC.
* Arrays.

Additionally users can create their own data types, which can be fully indexable by PostgreSQL GiST infrastructure. Some examples are data types created by the project GIS PostGIS. Other features


* also known as foreign key or foreign keys Foreign Keys (foreign keys).
* triggers (triggers), a trigger defined in a specific action based on something witty in the database. PostgreSQL this means the execution of a stored procedure based on a particular action on a specific table. Now all the triggers are defined by six characteristics:
The name of the trigger or trigger
The moment the shutter should start
The event trigger to be activated on ...
The table where the trigger is activated
execution frequency
function could be called

then combining these six characteristics, PostgreSQL allows you to create a wide functionality through its activation system triggers (triggers).

* Views.
* transactional integrity. * Inheritance
tables.
* Data types and geometric operations. Features



blocks of code that are executed on the server. Can be written in various languages, with the power that gives each of them, from basic programming operations, such as branches and loops, to the complexities of object-oriented programming and functional programming.

triggers (triggers in English) are functions linked to operations on the data.

Some of the languages \u200b\u200bthat can be used are: * A language

own call [PL / PgSQL [1] [2] (similar to PL / SQL for Oracle).
* C.
* C + +.

* Delphi * Java PL / Java web.
* PL / Perl.
* plPHP.
* PL / Python.
* PL / Ruby.
* PL / sh.
* PL / Tcl.
* PL / Scheme. * Language
R statistical applications using PL / R.

supports PostgreSQL functions returning "rows", where the output can be treated as a set of values \u200b\u200bthat can be treated equally to a row returned by a query (query in English).

Functions can be defined to run with user rights or the rights executing a previously defined user. The concept of functions, in other DBMS, are often referred to as "stored procedures" (Stored procedures in English).

We can work with postgresql from Delphi using components or components Zeoslib UniDAC , PostgresDAC these last commercial.

Online support available to this tool is broad. From the website http://www.postgresql.org can download the latest version installed (8.4.1) for different operating systems, Windows, Linux, Mac, Unix etc, plus access to a rich collection of documents and manuals, can solve most problems that often confront. If needed more help on the site are links to mailing lists, books and user groups.

In conclusion PostgreSQL is a serious alternative to the time of having a development involving the use of a database manager to match the major brands. Greetings

Free Text Encrypter

Good afternoon, these days reviewing components Jedi JVCL , suit free component, Encrypt tab I found a component name TjvCipher allowing encrypt and decrypt text depending a key (key ) that I am excited to develop this application (free download can and use at will) that allows encrypt a text which can be sent via email to another person and turn with the same program decrypt the destination for security.


As you can see the first panel allows you to write the text, which is encrypting in the second panel, the buttons indicate if this encrypting or decrypting text included. The master key is 123456 by default but can be changed by any number that PC. wish for more security when sending text, obvious to decrypt must use the same password that have been placed. The buttons let you copy, paste, delete or cut from / to any editor or transfer directly editor to send e-mail .


If they want to put decrypt encrypted text mark the first panel and ready decrypt

The installation program can not download it and paste it directly into the Windows desktop and run it from there. Well I hope will be useful, to the next.

Adjust Inventories

Good afternoon, some time ago I was asked to conduct a system of several things could change administrative a2 inventories. This required knowledge structures Blob fields SFixed file. Blb that contain both stocks as prices of Sale and Purchase (among other things). The reason for this system, according the applicant was able to download the inventory without direct adjustments without affecting the system and Inventory Report. addition that directly charge pending bills (which are stored in the printer without printing Attorney) view items in question and proceed to unload inventory. Well Transactions system does that and a little more then allows uploads and downloads directly interact with pending bills and maintain a historical of these movements independent of the administrative system.
This is a shot of the main menu


The system must be configured to indicate where the data of a2. You can also create multiple users , keys (USER: MASTER , CODE: 1234) and indicate the default price to which you have to work.



This is the download screen module


can download articles individually button to add


or also add batch from a2 bills pending in Upload button

expected



can print transactions It simply made or -screen viewing


The system has a query module, also of the options for change and charging products.


In conclusion here I give you the link for download (it's a fully functional DEMO) on file. Rar must unzip and run the typical setup and follow the installation instructions. For more information, please email to vicacos@gmail.com, vicacos@hotmail.com or 0424-429.71.67. Thanks

a2 a2 Softway DBISAM Client Server Professional Auction Table 3.58

this week was held in Caracas in the Halls of the Hotel National Convention Eurobuilding Dealers Software house a2 Softway CA Kamal Abidal and Its CEO representatives of the firm in Colombia unveiled the new developments that intend to apply to databases with the move to client server with version 4.8 of the database manager. It also discusses the new a2 Hotel, next to market, and other topics of commercial interest. Particularly I think it was just the change of ancient and DBISAM 2.8 (which has no support or in-house Company website Elevate Software) for the new client-server version 4.8.

While not the most robust in the world of data servers is a better option than the existing one. Many opt for Microsoft MSSQL example by perhaps Intebase Embarcadero Technologies, including MySql or Firebird, the last open source and proven track record in the world of SQL, without clutch the virtues of the engine chosen for the house is not detracting a2 considering that is the logical migration for development time (I think they were behind on this.)

From Elevate Software page to take this report:

DBISAM Server is a database manager robust, scalable, high performance, which provides client / server to get the benefits of speed and reliability that today their data needs.

rate file server system
  • When a terminal requests to the server, the requested information travels over the network to be processed locally. So if you have a 10mb database and run a search on it in which there were no data, 10mb of information contained in database travel the network cable.
  • This massive transfer collisions each terminal generates a low return on the net.
  • The server opens the database 1 time for each terminal. Eg. if your application opens 10 databases, so if you have 10 terminals, the server would open 100 files.
  • In case of failure in any of the terminals could generate corrupt indexes.
  • speed server response is not proportional to its processing capacity.
System client / server
  • When a terminal requests to the server, the requested information is processed by the server and only the response information is traveling over the network. This means that if you have a 10mb database and run a search on it in which no data, only travel a few bytes to the terminal via the network cable.
  • collisions are reduced by 90% or more, depending on the application.
  • The server opens the database once but many are accessing the terminal.
  • In case of failure in any of the terminals, the server closes the database properly and thus dramatically reduces the possibility of corruption of data or indexes. The server will not run requests incomplete.
  • speed server response is proportional to its processing capacity.
Soon we will be doing other comparative comments on this choice of server for the time until then.

Is The Direct Rewards Discover Card Good To Get



Good morning, I've been working on an application while it has nothing to do with a2 if components discussed in this Blog, this time I present the Professional Auction Table 3.58 a system made with components DevExpress, protecting Jvlc and using as MXprotector component. The novelty is that you use spreadsheets such as Excel (trademark of Microsoft) but not dependent on it. This is ideal sistemita Equestrian Centres in Venezuela and not in another part of the world what will make this way, but in conclusion here are some screen shots


The system can be configured to calculate the percentages for, as well as preview, automatic saving, the number of pages to print as well as a master key to protect the configuration changes.
Each table or worksheet records the corresponding pot as seen



There is also the screenshot of the settings tab is activated after verification of the password:


could not miss the credits tab About ...

Here 's also a shot of the report on screen generating system for the collection of bets:

The system can be downloaded from this address can try the version auque Registered NO , you can not print or set the default values. For additional information on pricing, as payment and shipping can communicate by cell phone 0424-4297167 or send an email to vicacos@gmail.com

Free Components Delphi Collection

Good Morning. Reviewing the various web sites on programming and / or information on Delphi I found this excellent blog on development and programming. Delphi is the Limit site that is to say it for more programming Delphi in a pedagogical manner and without any hint of pedantry explains in an entertaining way concepts of various types in Delphi. In found this link about free components for Delphi, but many others, I call attention especially TmxFlatPack .

Well as you can tell are very similar to those components that are made Softway a2, so if you plan to develop an application attached to this system May be used to maintain harmony among them. As the component
referred to in the Delphi Blog Limit the TmxProtector, I components used Ice License , but this component does not have anything that might miss the Ice license, soon will the respective tests:
This is the complete list of components with their respective links
  • TmxExports
  • TmxWebUpdate
Here I leave the link to the page in question:

These components are used at the Hey You (a2 to be precise) a great friend to me and I leave facilitated a PC. for evaluation. I am assuming that is not only access the information in the tables above named but also know how to show them (a task not easy Blob nested fields), but I leave a trail according to the latest work I have done: the structure is similar to the files of the former Saint DOS 7.5 (see the file TIPOS.DOC) ie Blob fields are contained records sFixed.dat the table is accompanied by their respective blob sFixed.blb which stores inventory information, customers, suppliers and others. Port example in this table is contained prices (1 .. 6) in the field encrypted blob FX_COSTOS, Well that's a good track to follow.

a2 Data Compressor

Buenos Dias. He presented a software to perform data backup for Softway a2. As you know the type a2 makes a backup copy that is as it as they do in the hard disk. With this program you can make backups, have control over them and also compress the data, we can also appends a security key, as well as the compression level. The program is made in Delphi Components ZipForge managing Firebird database local mode, that is embedded. For users it can Agragar a2 directly to the user menu of the application (a2 configurable) and make backups in a more secure, professional and compact. You can download the application (Installer Setup) from here .

Database Server Delphi 2007 for Programmers


Good Morning, review past dates superficially handler DBISAM database, which is used in version 2.08 Softway the a2 (I think it is the oldest, while there is no support for that version). This time I will quote the RDBMS and Management System Relational Database Firebird, which besides being open source and open source license, is a superior alternative when undertaking projects wingspan up to MySql, PostgreSQL, SQL Microsoft or Intebase fact Firebird is the result of the release of Interbase 6 and then rewritten to the current version 2.5 this amazing driver. Among its main features include:
  • is platform, and now can run on operating systems : Linux, HP-UX , FreeBSD, Mac OS , Solaris and Microsoft Windows . Executable
  • small, low hardware requirements.
  • Architecture Client / Server protocol on TCP / IP and other (embedded). Support
  • ACID transactions and foreign keys. Moderately
  • scalable. Good
  • user-based security / roles.
  • different architectures, including embedded Firebird ( embedded server) that allows single-user computers to run applications without installing the Firebird.
  • databases read-only applications that run from devices without writing skills, as cd-roms. Existence
  • ODBC driver , OLEDB, JDBC , PHP, Perl , . net, etc.
  • low management requirements, considered as a free database maintenance, regardless of the performance of backups.
  • Full support of SQL-92 standard both syntax and data types.
  • complete language for writing triggers and stored procedures called PSQL.
  • ability to store items BLOB ( Binary Large Objects).
  • Support User-Defined Functions (UDFs).
note that there is good work from components for Delphi and C + + with Firebird, you can name: Zeos Lib, FIB, FibPlus, IBO these last two payment but with excellent performance. Firebird
